1.Project summary
Protocol of Constantine Rabbi (Protocol of Constantine Rabbi is dedicated to
creating a decentralized monetary credit and securities asset investment and financing
system for the Jewish world. Jews have a mature business culture, in the modern capitalist
monetary banking industry also plays an important role in the creation of many world-
famous financial institutions, such as the famous Rothschild family, in London, Paris, Vienna
have a huge wealth, the impact on the European political economy can not be
underestimated, the Jewish people on the capitalist business operation mechanism,
industrial organization, the formation of the financial development system has also made a
great contribution. After World War II, the Bretton Woods system was formed, in which
Jews gradually dwindled, and under which credit, credit and securities investments had
many difficult pain points, Jews, as the ancestors of money banking, took on the
responsibility of this era, using blockchain technology to carry out a revolution in the
monetary and financial system.
On the basis of the traditional financial system, the Constantine Rabbi monetary
agreement is based on two starting points to establish its unique Defi system, one is to
establish a Defi-based credit system, the other is to establish a DAO-based asset
securitization certification system; Features cover wallets, asset management tools,
mortgage lending, aggregated income mining, derivatives, asset migration and creation,
DAO, predictors, and various POCR Data analysis tools, etc. The aim is to break the
many pain points and monopolies of centralized finance and establish a decentralized
monetary credit and securities asset investment and financing system of development,
civilization and self-discipline.
2. The background of the project
2.1Jewish Origins and Business Culture
According to the Hebrew Bible, the ancestors of the Jewish nation can be traced back to
Abraham, Isaac and Jacob around the 20th century BC. The Jews established three politically
independent states in their homeland, the Land of Israel, the two former and former kingdoms
of Israel in ancient times and the modern State of Israel, established in 1948. For most of
history, the Jewish nation began to live in a long-term wandering diaspora. With the exception
of the modern State of Israel, where Jews are minorities and have endured persecution and
repression by antisemitism, Jews have maintained the independence and continuity of their
national faith for thousands of years.
Jews have a mature business culture. On the one hand, jews have a long tradition of
doing business, their ancestors Hebrews were one of the earliest peoples in human history to
engage in business, the ancient Hebrews are located in the Canaan region of the unique
environment and social conditions gave birth to their sense of business. Canaan is located
between the Mediterranean Sea and the Arabian Desert, north of Syria, south of the Sinai
Peninsula, from the size of Canaan is not open, complex terrain, climate change. Although
there are some fertile and moist plain valleys , in general the amount of cultivated land and
pastures is small , and the water is insufficient , and the soil is poor . Geographically located
between Babylon and Egypt , and in the east-west traffic rush , has always been a
battleground for the strong , trade , war , plunder and other frequent historical exchanges ,
so that the Canaan region has long become a place of exchange between different
nationalities , different tribes and different cultures . The deficiency of internal production and
the objective condition of "the place of communication " make Canaan play an important role
in the early trade history of the West Asian region. Here, "there is a lively road through the
coastal plains, from the Euphrates river and the Tigris River countries of the army and business
brigades from this road into the Nile Delta."
Since modern times, with the rapid development of capitalist economy, the strength of
the Jewish bourgeoisie has been increasing day by day, and in the fierce competition of free
capitalism, they have made great profits by investing in industry, transportation, commerce
and so on. In19th century Europe there were many Jewish billionaires, creating many world-
famous financial institutions, such as the famous Rothschild family, in London, Paris, Vienna
have a huge wealth, the influence on the European political economy can not be
underestimated, the Jewish people on the capitalist business operation mechanism, the form
of industrial organization, the formation of the financial development system has also made
a great contribution, many of the most popular economic instruments in the world today,
such as negotiable instruments, government bonds and so on are Jewish inventions. Not only
that , but also for the emergence and development of stock trading : the world's first
permanent joint-stock company , the Dutch East India Company , was founded by Jewish
merchants , and jews accounted for 25% of the shareholders of the company , founded in
1602 ; Jews dominate the Amsterdam Stock Exchange , the world's first official stock
exchange , with 37 of the 41 members of the exchange . In addition , Jews hold very
disproportionate seats on stock exchanges in places such as London . Because of this, there
was a saying among Europeans that infidels contributed to the formation of the spirit of
commerce. Marx also believed in "On Jews" that the embryos of modern European and
American societies existed in the "Jewish spirit" and that "civil society has continuously
produced Jews from within itself".
Therefore, reinventing the capitalist market finance industry through the great invention
of the blockchain technology era has become the innate responsibility and mission of the
Jews!
2.2Blockchain
Blockchain, as a new technology born from a combination of technological innovations,
mainly covers the concepts of cryptography, network transmission protocol, distributed
storage and other technologies.
Trading, trading is the basic unit in the blockchain. The reference to the term
transaction in the blockchain is derived from the Bitcoin application and can be narrowly
understood as a record of a transaction in a digital asset and broadly as a record of any
behavior on the blockchain. Typically, a transaction needs to include the following fields:
random numbers to ensure the uniqueness of the transaction, the node address of the
transaction initiator, the node address of the transaction recipient indicating who received
the transaction, the transaction information, including the transaction amount and
transaction information, and the data information used to confirm the legality of the
transaction initiator's ownership.
Block, which is the primary unit in the blockchain. By packaging multiple transactions
into one block, multiple blocks are connected using hash technology to form a blockchain
data structure. Typically, a block needs to include the following fields: the front hash, the
hash value of the previous block, the block transaction information, usually the root value of
the block transaction stored using the Merkel tree data structure, the block number, the
block serial number value, and the timestamp, which refers to the total number of seconds
from 00:00 today on 01 January 1970 GMT.
Nodes, the basic units that make up a blockchain network. In a blockchain network, a
point with complete blockchain data is called a full node, and the entire node can
participate in consensus. Nodes that have only part of the blockchain data or can only
access the blockchain through the full node are called light nodes, which typically do not
participate in consensus.
Consensus algorithm, algorithmic logic for reaching consensus on new blocks between
nodes. Typically, each node in a blockchain network packages different new blocks, and only
through the blockchain consensus algorithm can all nodes add the same chunk. Compared
with the traditional distribution consistency algorithm, the blockchain consensus algorithm
not only needs to ensure the consistency of block data, but also can resist the Byzantine
general problem attack.
The right to bookkeeping, the right of nodes to add block records to the blockchain
ledger. The nodes of the consensus algorithm have bookkeeping rights, and the nodes with
bookkeeping rights can determine the new blocks. Because the new blocks packaged by
each node in the blockchain network are different, it is necessary to determine by consensus
algorithm that the new block will be added to the blockchain ledger by the unique node,
after which the other nodes will synchronize the new block on the accounting rights node
according to the blockchain synchronization rules.
Smart contracts, a piece of logical code based on blockchain consensus. Generally in
blockchain systems, smart contract code is recorded in the blockchain after consensus, and
contract calls are automatically executed in the blockchain virtual layer.
First, the node user's record of operations in the blockchain system forms a transaction,
in which case the transaction is stored in the local node, then each node packages the local
transaction and the legitimate transaction received through the P2P(Peer-to-Peer)protocol
into a newblock; A deployed smart contract is equivalent to a transaction in a blockchain,
and the user can generate a transaction by calling the smart contract.
2.3Important applications for Defi-blockchain
DeFi(Decentralized Finance): Decentralizedfinance or distributed finance --- a new
network of financial services robots. Decentralized finance refers to the applications of
various financial fields developed in open decentralized networks, with the goal of
establishing a multidimensional financial system based on blockchain technology and
cryptocurrencies, without relying on centralized servers, to re-create and improve the
existing financial system.
Traditional finance includes fintech, and blockchain is one of the most important
innovations in fintech, while Defi is only a very segmented branch of blockchain digital
currency, but it is one of the most important applications. Compared to traditional financial
services,POCR systems have the characteristics of a Defi native advantage.
⚫ Global Financial Services Inclusive: Decentralized Finance enables anyone to access
financial services via the Internet or smartphone. At present, the traditional financial field of
the threshold for users is very high, in terms of identity, wealth and geography have strict
control. Only decentralized distributed finance can minimize costs and popularize finance
through the most primitive means of communication, such as mobile phones and the
Internet.
⚫ low-cost payments: the middle of decentralized finance omits the costs of
expensive intermediaries, effectively reducing the cost of remittances and reducing the cost
of friction between financial operations.
⚫ increased privacy and security: in the decentralized financial system POCR, users
keep their property and trade securely without central verification. At the same time, in the
traditional financial sector, trustees are responsible for the custody of users' property and
information, and in the event of a leak, the consequences are unimaginable.
⚫ transactions:AllPOCR business records are non-changeable. Blockchain cannot be
shut down by a centralized organization.
⚫ easy to understand: the process of centralized financial system is too complex and
cumbersome, decentralized financial system can reduce excessive authentication services
through the private key, to provide users with simpler and more convenient services.
2.4rabbi
Rabbi, the spiritual leader, is a special class of Jews, a teacher and a symbol of the wise,
referring to regular Jewish education, systematic study of Judaism classics such as Tanah,
Tamud, as spiritual leaders of the Jewish community or the Jewish Church, or teaching Jewish
teachings in the Jewish Academy, mainly by learned scholars. A person who is responsible for
enforcing the rules, the law, and presiding over religious ceremonies.
3.Analysis of pain points in the centralized financial
system
3.1The financial system and user interests are separated, and
the participation of ecological users in the financial system is
low
The most essential or core function of the financial system is pure lending, including
trading, lending, asset synthesis, mortgage, liquidation, and the undertakers of both sides of
the business are the vast number of financial system users, user participation is the source of
vitality of the financial system. In the traditional financial system ecology, users only participate
in the activities of borrowing and lending digital currency, or follow the traditional "pawnshop
thinking" and "money housethinking", do not fully absorb the essence of Jewish business
wisdom and cultural unity and trust, do not participate effectively in the construction of the
financial system community, also do not enjoy the financial system development and
operation process of dividends, do not integrate users into the growth trend of financial
enterprises, so that the financial system users and platform interests are divided, can not
achieve a win-win ecological structure.
3.2The asset security mechanism is backward
The security of user assets of financial system has always been the most important link
of the long-term stability of financial system, and the centralized server is very vulnerable to
all kinds of attacks, and the internal operation has a very high moral risk, which makes the
decentralized financial system come into being. In 2014, 650,000 bitcoins were stolen from
the world's largest MT.GOX bitcoin financial system, and the platform went bankrupt because
of its inability to repay it. In 2016, 120,000 bitcoins were stolen from the Bitfinex Bitcoin
Trading Center, resulting in a direct loss of 36% of Bitcoin's digital assets. Jewish people
thrive in business and are closely linked to their relatively secure spirit of contract, which is
the most fundamental commitment to users, and digital asset security is the cornerstone of
the long-term coexistence of users and platforms.
3.3The technical architecture is backward and the system
stability is poor
At present, the financial system has a large number of backward technical architecture,
system instability problems, peak period often downtime. These make it impossible for users
to trade in a timely and effective manner and other operations, investment timeliness is poor,
investment damage, extremely serious impact on the interests of users, curbing the good
development of the market.
3.4A centralized financial system does not guarantee
transparency in transaction information
Opaque information is an inherent weakness of the centralized financial system, when
the user uses the centralized financial system, the currency right is fully in the hands of the
financial system, the user's assets are stored in the wallet of the financial system, any
misappropriation of funds is difficult to be detected by the outside world. On the other hand,
the user's personal data is stored in a centralized server, once the user's privacy security can
not be protected. Centralized financial system using back-office data directed bursts and
other events are not uncommon, but also the possibility of insiders using background data to
do mouse silos. In the financial system release of IEO and other activities, because the
information data is not open and transparent, to the platform side retained the possibility of
covert operation, can not guarantee the fairness of activities.
3.5Assets go online in disarray and user interests suffer
At present, the vast majority of financial systems charge high online fees for digital
assets, which leads the financial system to choose online digital assets in favor of
maximizing the benefits of the currency, thereby indirectly undermining the value of the
high-quality currency in the hands of investors. While these high currency fees can bring
higher returns to the financial system in the short term, in the long run, not only will the
interests of investors be damaged, but will also have irreversible negative effects on the
industry's atmosphere.
At the same time, one of the biggest problems in the financial system is that its
currency rules are confusing. Not only is the currency rule very unreasonable, and the
frequent change of the rule is common. The core objectives of the financial system are to
ensure profits, so the rules of the currency is not deliberately maintained, the process of
currency is not transparent, lack of service for the entire blockchain industry, to create value
for users of the core concept.
3.6Illiquidity, poor lending experience
Project participation and market enthusiasm are different, some project trading orders
are limited depth, liquidity is insufficient, day-to-day life is bleak, while the spread is huge,
sliding point is serious, the volume shrinks, seriously affecting the user's borrowing, trading
experience and realization rate, so that the user's digital assets can not effectively circulate
and trade between the borrowers and borrowers. Traditional solutions such as trading mining
diversion, trading rebate activity diversion, looking for market cooperation, etc., can only build
depth in a short period of time, the end of the activity still can not guarantee better liquidity.
Incentives such as liquidity mining are therefore urgently needed to provide sufficient liquidity
for credit and transactions and to enable participants to derive asset gains from them.
4.POCR blockchain key technical analysis
Blockchain as a new product of multi-technology fusion, the key technologies involved
include cryptography, distributed storage, consensus algorithms and smart contract
technology. With the development of blockchain technology,DAG(with ringless graph)
technology, cross-chain technology, sharding technology has also been included in the
application of POCR.
4.1Cryptography
The cryptography techniques involved in blockchain include hash functions, digital
signature technology, digital certificate technology and zero knowledge proof technology,
which are cryptography techniques that compress a piece of data into a specified length, and
generally have one-way and anti-collision resistance. In blockchain, hash functions have three
main functions, one is to obtain a summary of a transaction data or block data to ensure data
integrity, the other is to connect the front and rear blocks, as an important part of the
blockchain data structure, and the third is to build the Merkel tree (a tree structure based on
hash algorithm) to make block data non-tamperable.
In addition, in the consensus algorithm of workload proof, the anti-collision resistance
of hash function is used as the acuity guarantee of difficult problems. Digital signature
technology is an important technical means to realize the transaction verification mechanism
in blockchain. When the ownership of a digital asset changes, it is often necessary to verify
the legitimacy of the current digital asset digital signature, followed by the new owner of the
asset to sign it. Digital certificate technology is the core component of
CA(CertificateAuthority)technology.
In a federation chain network, blockchain nodes often need to be authenticated before
they are allowed to join the blockchain network, and the identity of the blockchain nodes can
be managed through the CA.
Zero-knowledge proof technology refers to cryptography techniques in which a certifier
can convince a validator of an assertion without providing any useful information to the
authenticator. In blockchain, zero-knowledge proof technology is mainly used for the
protection of transaction-sensitive information, in the realization of transaction legality
verification, without disclosing any private information about the transaction. In addition to
the cryptography mentioned above, the combination of cutting-edge technologies such as
homologous encryption and multi-party computing and blockchain technology is constantly
being explored.
4.2 Distributed storage technology
In traditional distributed storage, data storage mainly includes data distribution and data
replication. Data distribution refers to the distribution of all data according to a certain pattern
of distribution on different nodes, nodes store only part of the data, and data replication
refers to all nodes need to store complete data. In a blockchain system, blockchain can only
provide two operations of addition and query due to the limitations of the underlying data
structure, and in order to achieve the storage goal of decentrization, all nodes will store the
complete blockchain data according to synchronization rules. Typically, synchronization rules
refer to all nodes that need to be consistent with the longest blockchain (the largest block) in
the network. Blockchain data replication is achieved through blockchain data structures and
strict synchronization rules.
The distributed consistency algorithm used in blockchain is the final consistency
algorithm, i.e. after a block time, all the data on the blockchain is agreed upon. The
PoW(Proofof Work)algorithm used in public chainnetworks is a typical final consistency
algorithm. First, the miners are elected by means of competition to solve difficult problems,
the miners determine the latest blocks, and after the other nodes synchronize the new blocks,
the blockchain network agrees on the transactions in the new blocks. The
PBFT(PracticalByzantine-Fault-Tolerance)consensus algorithm used in the federation chain
network isstrictly a strong consistency algorithm, i.e. the result of a transaction being agreed
upon through a three-segment interaction. However, data updates on the blockchain are
usually in block time, so in a typical POCR blockchain system,the PBFT algorithm is used to
agree on the results of block sorting, and a transaction still needs to be completed at the end
of the block time before it can take effect. In order to realize the decentrization characteristic
in the true sense, the blockchain network needs to give the nodes in the network more
inclusive, so once the evil node exists in the blockchain network, it may cause the Byzantine
general problem. The problem of resisting Byzantine generals is another difference between
distributed consistency algorithms and traditional distributed consistency algorithms in
blockchain, and both distributed consistency algorithms used in federation chain and public
chain blockchain networks need to meet this characteristic. The algorithms in the blockchain
that solve the Byzantine general problem and achieve distribution consistency are often
referred to as the blockchain consensus algorithm.
4.3 Consensus algorithm
The main purpose of the consensus algorithm in blockchain is to resist the Problem of
Byzantine Generals and to ensure data consistency on blockchain. With the continuous
development of blockchain technology, the consensus algorithm applied in different
scenarios has been proposed, the following will be mainly in accordance with the consensus
algorithm application scenarios, the consensus algorithm is divided into public chain
consensus algorithm and alliance chain consensus algorithm, and take the typical consensus
algorithm as an example, its resistance to the Byzantine general problem and the completion
of data consistency of the working principle of analysis.
The main difference between the public chain consensus algorithm and the alliance chain
consensus algorithm is that the public chain is a public network with no access restrictions, so
the public chain consensus algorithm does not depend on the node state in the current
blockchain network. In general, the consensus algorithm based on proof is adopted in the
public chain, that is, the blockchain node can complete the consensus process by obtaining
the proof of bookkeeping right based on a certain limit. Typical proof-based consensus
algorithms include a nuance-based PoW consensus algorithm, an equity-based PoS(Proofof
Stake)consensus algorithm, and a delegated equity-based DPoS(DelegateOf Of
Stake)consensusalgorithm.
4.4 Smart Contract Technology
Smart contracts are a set of determining code that can run on any blockchain node, so
smart contract technology includes the smart contract language design and the virtualization
environment design required for smart contract code to run. The Ethereum blockchain system
and the POCR blockchain system, which are widely used at present, adopt different design
methods,andPOCR will analyze the blockchain smart contract technology and how it works
by using these two systems as examples. Ethereum Smart Contract is the first truly blockchain
smart contract, compared to the Bitcoin blockchain system, which can only achieve a single
script function, Ethereum smart contract has Turing's complete contract language and perfect
virtualization environment operation mechanism. Exclusive smart contract languages such as
Solidity,Serpernt, and LLL are available inEthereum. As an advanced contract language,
these smart contract languages can compile a uniform bytecode from the appropriate
compiler, which will run in EVM(Ethereum Virtual MacPOCRne). EVM is a stack-based virtual
machine that records the results of a bytecode run in a blockchain ledger. Solidity is used as
an example to analyze how Ethereum smart contracts work. When you deploy a smart
contract, the account writes solidity contract source code, then compiles the contract source
code into bytecode through the solc compiler, and finally publishes the bytecode to the
blockchain, which is deployed successfully. When a smart contract is called, the user initiates
a smart contract transaction, the miner who gets the bookkeeping rights gets the bytecode
of the smart contract, runs the bytecode in the local EVM, and finally records the results of
the transaction on the blockchain.
The POCR blockchain system uses a different design mechanism than the Ethereum
smart contract. The first is its adoption of more general, advanced programming languages
as smart contract languages, including Golang and Java. Second, instead of continuing with
virtual machine-centric virtualization technology, POCR leverages Docker technology to
provide a virtualized operating environment for smart contracts. Because of the different
design mechanisms, POCR smart contracts work differently from Ethereum, and the Golang
language is used as an example to describe how smart contracts work. When deploying a
smart contract, the client node first writes the Golang contract source code, adds the source
code to the client container, then generates a unique contract run environment image by
executing the contract installation command, and then executes the contract instantiation
command to launch the contract container, at which point the new smart contract is deployed
in the launched container. When a smart contract is called, the client node initiates a contract
call transaction request, the contract container responds to the transaction request and
executes the transaction at the same time, and then records the transaction results in the
blockchain ledger.
It should be added thatthe POCR blockchain system is a federation chain network that
contains different functional nodes and performs more complex validation and consensus
mechanisms between nodes,as described in thePOCR white paper only for the smart contract
run process.
5. POCR Blockchain Asset Securitization Service
Platform
Blockchain-based asset securitization service platform refers to building a third-party
service platform based on blockchain. The service platform combines blockchain with the
business scenario of asset securitization, so that participants in asset securitization business
can obtain and participate in the verification of data generated by the service platform in real
time, so as to ensure that the transaction data generated by the service platform is true and
reliable, improve the transparency of asset securitization business processes, and enhance
mutual trust between business participants.
POCR blockchain asset securitization service platform brings six advantages: first, to
provide securitization product projects, basic asset collection and screening, productdesign,
product issuance, survival management of the entire life cycle of electronic management;
Third, the model is rich, all kinds of quantitative analysis models can be used to support the
design of the split structure, cash flow comparison and analysis, default indicator analysis,
asset characteristics analysis and so on. Fourth, flexible configuration, a variety of asset
screening packages, product design support programs, product cash flow distribution
sequence flexibility, fifth, advanced technology, with resource isolation mechanism, business
rights management, underlying security reinforcement and other powerful information
security management mechanism and anti-attack system and professional operational
capabilities;
POCR blockchain asset securitization service platform can give full play to the de-
trusting of blockchain technology, difficult to tamper with, decentralized, distributed
broadcasting and so on, to solve the difficult problems of asset securitization ecology:
(1) The use of blockchain technology is difficult to tamper with, de-trust, distributed
characteristics of the service platform to achieve the distributed storage of data, through the
consensus of participating nodes within the platform to ensure data trustworthiness and
consistency;
(2) The survival period of asset securitized bonds involves investors, managers, trustees,
etc., and with the support of blockchain distributed network communication technology, the
trading information during the life of asset securitization bonds is transmitted to the manager
in a timely manner, so as to avoid the problem of the wrong object of bond interest issuance
and improve the accuracy and efficiency of the data.
5.1POCR blockchain asset securitization service platform vision
POCR combines blockchain and asset securitization business to try to build a blockchain-
based asset securitization service platform in the Jewish world to meet the criteria of screening
underlying assets in asset securitization business, assessing the risk of underlying assets,
designing asset securitization bonds, and disclosing information during the life of bonds The
application demand, eliminate the obstacles in all links of asset securitization business, realize
the data exchange and sharing between all links of asset securitization business, and construct
the ecological chain of asset securitization business, so that all participants in asset
securitization business can obtain the convenience brought by the asset securitization service
platform and promote the rapid development of asset securitization business. The DESIGN
OBJECTIVES OF THE POCR BLOCKCHAIN ASSET SECURITIZATION SERVICE PLATFORM ARE
AS FOLLOWS:
(1) Building a decentralized and detrusted asset securitization service platform based on
blockchain is essentially a service platform designed with blockchain as the basic technology
architecture. In this service platform, all participants in the form of nodes, through peer-to-
peer network transmission technology into the blockchain, thus forming a decentralized, de-
trusted structure.
(2) Eliminate the information transmission barriers in all aspects of asset securitization
business and realize the integration of resources and data sharing between the various links .
In a service platform based on blockchain technology, all participants in asset securitization
business should join the service platform as a node in the blockchain under the leadership of
the China Fund Industry Association. Because the service platform has the characteristics of
de-trusting, this makes the mutual cooperation between nodes and the interconnection of
related data realize at a very small cost, thus solving the problem of data interconnection
between the various links in the current asset securitization business, and realizing the
business collaboration between the various links.
(3) To realize the rapid transmission of information about the subsequent process of the
bond
The service platform can electronicize the entire process of asset securitization business,
providing a one-stop solution from the screening of underlying assets, risk assessment, bond
issuance, and information disclosure of bond life. Simplify the business process of asset
securitization, improve the efficiency of intermediaries and reduce the risk of investors.
(4) Improve the level of regulatory oversight
Based on the blockchain architecture and facing the Internet, the service platform
combines the asset securitization business with the blockchain technology depth, enhances
the degree of connection between the various links of the asset securitization business, the
supervision and management department can obtain the information of all aspects of the
business in a timely manner, improves the management efficiency of the supervision and
management institution, and also enhances the speed of the information construction of the
asset securitization business.
5.2POCR Asset Securitization Services Platform Architecture
Design
The structure of POCR securitized service platform mainly refers to the structure
relationship between various function modules within the service platform, and the related
function modules constitute the service platform. A structure diagram is the easiest way to
describe the structure of a service platform, and it is a simple summary of the purpose of the
structure diagram, so even non-professionals can understand the structure of the platform
through the service platform diagram. The software structure of the service platform describes
the various aspects of data transmission and is described in more detail below. The design of
the software structure of this service platform can be divided into three parts: the first part is
the data layer, the second part is the service layer, and the third part is the application
presentation layer.
(1) The application presentation layer is mainly responsible for the user interface
interaction of the service platform, and the better performance layer design can bring a good
visual experience to the user, thus enhancing the user's experience of the service platform,
and also promoting the promotion of the service platform.
(2) The service layer is mainly to support the presentation layer, the user of the service
platform through the presentation layer of the service request, the presentation layer will
obtain the request will be passed to the service layer, the service layer accepts the request
immediately after processing, and quickly feedback the processing results to the presentation
layer, and then the presentation layer will present the results in front of the service platform
consumers. Its more typical is the implementation of platform user information query
requirements.
(3) The data layer is often referred to as the data access layer and its primary responsibility
is to manage the storage, synchronization and backup of data on the service platform. The
data persistence layer of this service platform can be divided into 2, respectively, the local
database and blockchain, the local database is mainly stored on the service platform user
information, to achieve the digital management of the user information of the service
platform; The data persistence layer is the core part of the service platform and the foundation
of the dynamic system.
5.3The physical structure of the POCR asset securitization
service platform
Based on the underlying technology of blockchain, the asset securitization service
platform realizes the non-tampering of stored information by storing information such as the
management of basic assets, the design of asset securitization bonds, the issuance of asset
securitization bonds and the disclosure of information during the existence of asset
securitization bonds. At the same time, because the information of the service platform is
stored in a decentralized platform, users can query the relevant information through the
blockchain to verify the "transparency" of the underlying assets and the information
generated by the various processes of the asset securitization business.
The architectural design of the service platform is a very important part. The network
topology architecture determines the performance, security, and stability of the service
platform. In the design and implementation of the asset securitization service platform based
on blockchain technology built in this paper, four Linux servers with blockchain underlying
programs installed are first deployed as nodes in the blockchain, and a profile of 4 nodes is
configured to enable 4 nodes to reach consensus and the underlying blockchain to form.
Blockchain network uses its own nature to ensure the security and effectiveness of
transactions, in the realization of the role of decentralization, to ensure that transactions can
not be tampered with.
Users can access the service platform deployed on the web application server through
terminals such as computers and mobile phones, and conduct business operations such as
basic asset management, asset securitization bond design, asset securitization bond issuance,
and information disclosure during the life of the bond.
The physical structure of the service platform consists of four phases, the first of which is
that the user of the service platform makes a request to the blockchain server over the Internet,
and after the blockchain server receives the user's request, the user's request is judged, and
the next stage of operation is carried out if the pre-set rules are met. The second stage is the
blockchain server to reach an internal "consensus" stage, the main function of the stage is to
the service platform generated by a user of the transaction data completed storage to the
blockchain server, where any blockchain server receives the user's request, the request will be
immediately passed to other blockchain servers, and the rest of the blockchain server
"consensus", "consensus" agreed to indicate that the transaction data through authenticity
verification, can be stored in the blockchain server. The third stage is to store the data
returned by the blockchain server in a local database that acts only as a secondary backup,
and the real data from the service platform exists in the blockchain. Finally, the service
platform is based on data stored in the local database to meet the needs of consumers.
5.4The POCR API interface
The service platform interface layer refers to the interface provided by the blockchain to
the developer, which is described next.
Of these interfaces listed above, they can be divided into two types in general, one
interface is a write type and the other is a query type, where POST is the request method
used by the interface of the write type, and GET is the request method used by the interface
of the query type.
5.5 Asset Securitization Services Platform module functional
design
There are four main functional modules of the asset securitization service platform,
namely, the basic asset management module, the design module of asset securitization bonds,
the asset securitization bond issuance module, and the information disclosure module during
the survival of asset securitization bonds.
5.5.1Basic asset management module
The module mainly includes recording the basic asset information function, querying the
basic asset information function, forecasting the basic asset cash flow function, evaluating the
basic asset function and so on.
The original owner records the information of the underlying asset to the blockchain
server through the platform, and the generation process of a single block can be divided
into three steps
(1)The generation of the underlying asset
Suppose an enterprise now needs to record accounts receivable information from a
new transaction into the blockchain. When an A enterprise makes a request for accounts
receivable information record to the underlying asset management module in the asset
securitization service platform, it is assumed that the B node controlled by the intermediary
is selected by blockchain as the bookkeeper of the accounts receivable information through
the consensus mechanism.
After the enterprise generates accounts receivable, it makes a request to record accounts
receivable information to the basic asset management module in the asset securitization
service platform, and encrypts the accounts receivable data through the enterprise's private
key, and the encryption algorithm ensures the data security. In the blockchain, the nodes
controlled by the intermediary are encrypted again for the information received, resulting in
data redaction.
(2)Other node authentication
After the node controlled by the intermediary encrypts the data of the account
receivable, it is sent to the other nodes in the blockchain in the form of broadcast, and the
nodes of the other nodes decrypt the encrypted data to obtain the accounts receivable clear
text. Then the information of the initiating enterprise, the nature of the transaction, the time
of the transaction, the amount of the transaction and other information of the account
collection data are verified, and after the verification is passed, the accounts receivable data
is added to the block to be accounted for, waiting in line for confirmation of the mining node.
After the last accounts receivable block is generated, the nodes in the system begin
mining the new accounts receivable blocks. In the accounts receivable blockchain, mining and
accounting is done through nodes controlled by the intermediary structure. When the
random number calculated by the mining node meets this condition, it can be broadcast to
inform the other nodes in the system that the other nodes are validating the newly generated
accounts receivable block, and if the accounts receivable data, timestamp, and data structure
of the block are not verified, the mining nodes in the system will resume mining work again.
If the newly generated accounts receivable block has passed the verification of all nodes, the
mining node will automatically obtain the accounting rights, and all nodes in the system will
attach the address of the node and other relevant information to the head of the new block
as a basis.
5.5.2Asset securitization bond design module
Mainly includes screening the basic asset function, the formation of the basic asset pool
function, browsing and maintaining the asset pool function, design bond scheme function
and so on.
The main users of this functional module are intermediaries, the main underwriters
through the basic asset management module to obtain the basic assets of the relevant
information, from which to filter out the eligible underlying assets, and set up the basic asset
pool, based on the asset pool of the underlying assets expected to generate cash flow, the
design of bond schemes.
The lead underwriter sends the designed scheme through the Asset Securitization
Service platform to the nodes (investors, regulators) involved in subsequent transactions, each
of which agrees to write that information into the block.
The height of the newly generated chunk of the system is represented by New Height,
which acts as the base block for consensus. Using the existing block height as a basis to
produce a new block usually requires several rounds, each with a node as the new zone
fast-generating sponsor, which exercises the right to initiate the validation of the new build
block by making a proposal. The remaining nodes involved in the consensus process
exercise the right to negation or approval based on the contents of the proposal
(Propose),and the system determines whether each node agrees on the new generated
block based on the results ofthe pre-vote (Prevote)and if thenodes agree on the voting
result (i.e., more than 2/3 nodes vote in favour of the vote) The newly generated chunk is
committed and returned to the New Height stage, and if the nodes do not agree on the
results of the vote (i.e., the voting result is more than 2/3 nodes empty or the nodes
participating in the voting are less than 2/3of all nodes inthe system), the system enters the
next round of consensus (). New Round）。
5.5.3 Asset Securitization Bond Issuance Module
The module mainly includes recording investor information function, investor's quotation
function, recording bond transaction information function, etc., the main users of the module
are the main, sub-underwriters and investors, investors through the module to deal with the
issued bonds to quote, the main and sub-underwriters through the module to complete the
bond sales work, while the quotation information, bond trading information, participating
investor data saved to the blockchain server.
The system master node collects the transactions after each participating node signs,
and then verifies the collected signatures, and the signatures verified by the primary node
are considered to be real and legitimate transactions.
5.5.4Information disclosure module for the life of a bond
The module mainly includes bond query function, cash flow warning function, bond
interest automatic repayment function and so on.
The module's main user investors and regulators, which assess the risk of bonds by
checking the repayment of bonds and the recovery of cash flow from underlying assets, can
improve the efficiency of supervision, and investors can grasp the default risk of underlying
assets in real time through the early warning function of cash flow, thus improving the level
of risk management and avoiding losses caused by bond defaults.
6. POCR credit system
On the basis of system requirements analysis and functional description, the system
design is completed for blockchain-based personal credit system. The system summary
design part mainly describes the approximate technical architecture of the system and
completes the overall system architecture design. The detailed design part is the detailed
design of the specific contents of credit blockchain, identity management module, data
acquisition module, credit score module, scoring fusion module and report generation
module. In the data storage design part, the storage scheme of blockchain system is
introduced, focusing on analyzing the problem of credit data chaining in blockchain-based
personal credit system.
6.1 POCR Credit System Summary
The system mainly provides services for three types of users: the first category is only
for the purpose of querying personal credit reports for individual users, the second category
is responsible for identity management and authentication of administrator users, and the
third category is as the system use of the main credit node users. This system provides
credit report query service for individual users, which communicates with credit nodes in the
credit blockchain network through external applications and obtains query services.
Therefore, individual users are not the focus of the system design considerations, only need
to provide them with access to relevant credit reports of the application interface.
Administrator users of all credit nodes in the system for authentication and management,
this part of the service is mainly based on the Fabric project supporting the certificate
authorization mechanism to achieve. Credit node users are the main users of this system,
the system mainly provides the basic personal credit mechanism for this part of the users,
while providing them with solutions to the current industry pain point problems. Credit
node users are the entrance to obtain the original personal credit data, in reality may be
enterprises, government departments and public welfare organizations. In order to realize
the protection of sensitive data within the organization, it is necessary to divide the credit
node users into ordinary credit node users and anchor credit node users. Ordinary credit
node users are responsible for basic data collection and participate in the operation of the
blockchain consensus mechanism in the primary credit network. Anchoring credit nodes
have all the functions of ordinary credit points, in addition, it is necessary to form a high-
level credit network on behalf of the primary credit network in which they are located. Only
anchor credit node can provide credit report query service for individual users, and ordinary
credit node does not communicate directly with individual users.
The personal credit system consists of three components, namely, the application part
of the personal user credit report query, the identity management part of the credit node
and the main system part of the personal credit. The query part of the personal user credit
report provides the information query service for the individual user, adopts the basic B/S
architecture, and realizes the personal user data query service based on the query interface
provided by the personal credit main system. This part of the design work focuses on the
design of external query interfaces. The identity management part of the credit node mainly
provides the identity management service to the credit node, this part adopts the more
mature open source CA framework, distributes the corresponding ID card and private key
for all credit node. The personal credit master system provides blockchain-based personal
credit system services for all credit node users, and realizes distributed credit data collection,
data analysis, credit report generation function. At the same time, the main system of
personal credit is also the background system of individual user credit results query,
providing credit report data for individual users. The main system of personal credit is also a
perfect blockchain system, and the credit node also forms the credit blockchain network as
the blockchain node. In the credit blockchain network, the primary credit network is
composed of ordinary credit nodes, and the anchor credit nodes in each primary network
constitute the advanced credit network. The identity of ordinary credit node and anchor
credit node depends on the identity management system.
6.2 POCR credit system function
6.2.1 Jewish Identity Management Feature Design
Identity management function relies on the personal credit system supporting CA
system implementation, administrator users log on to the CA client, for credit node users to
register identity information. The main functions provided by the CA system supporting the
personal credit system are: registering the corresponding identity information for the credit
bureau node, issuing the identity digital certificate to the registration node, and renewing
and revoking the identity digital certificate. The CA system interacts with the CA service
side in a client-side manner. The CA client connects to the server, which has an identity
database that holds the user's certificate information. It should be noted that when the
administrator logs on to the CA client for the identity registration of the credit node,the CA
service side needs to do two permission checks: first, the administrator identity of the
administrator node needs to be checked, the ordinary credit node users can not register;
6.2.2Data acquisition function design
In the current personal credit industry, the collection of personal credit data mainly
includes two kinds: one is the traditional personal credit data, the other is the internet credit
data in the context of big data. Traditional personal data refers to the personal credit data
obtained by public credit bureau organizations such as the Chinese People's Bank credit
center, relying on government departments, banking institutions and telecommunications
companies, etc., which is presented directly in the personal credit report by the credit
bureau after aggregation, processing and integration. Internet credit data mainly refers to in
the context of big data, private credit companies with the help of the Internet to obtain user
credit data, this part of the data mostly by credit scoring model processing, and finally in the
form of credit scores to show users.
Typical Internet credit data such as financial data obtained by Internet financial
enterprises, e-commerce platform access to e-commerce data. Because the personal credit
system finally generated the credit report also includes personal credit information and
personal credit score two parts. In terms of personal credit information, emphasis will be
placed on the collection of customized traditional personal credit data, including basic
personal information, credit records, public records and query records. In the credit score to
obtain credit data, in principle, according to the specific business scenario as much as
possible to collect user Internet credit data, data content can be divided into identity
characteristics, performance ability, credit history, behavior preferences and network
relationship five aspects. In addition to the different contents of data collection, different
collection schemes need to be designed for different credit data. In the collection of
personal credit information data, the use of customized collection programs, that is, by the
government, banks, telecommunications and other institutions composed of credit network,
the use of customized data collection smart contracts to collect designated credit data.
When collecting credit score credit data, the credit network composed of Internet
enterprises as the main body collects non-customized credit data according to the business
characteristics of enterprises.
6.2.3Credit scoring feature design
Jews have regarded credit as one of the most important elements of the market
economy since ancient times, and it is involved in many classics. The credit scoring function
is designed to analyze the credit data collected by the credit nodes in the primary credit
network in the POCR system, and to obtain the primary credit score of individual users
through the credit scoring model. The credit scoring model draws on the fiCO scoring
model commonly used in the world, but in the specific application, each primary credit
network will develop the appropriate credit scoring model according to its own business
characteristics. The general idea of establishing credit scoring model is: first, to determine
the proportion of each credit score dimension in the credit score, second, to determine the
credit index under each credit dimension, then to select the sample data, to distinguish the
sample data into "good" and "bad", to classify the sample data, to calculate the number of
"good" individual users and "bad" individual users in each indicator;
6.2.4Scoring fusion feature design
The design goal of scoring fusion function is to integrate the primary credit scores
obtained by each primary credit network and obtain a unified credit score. The basic idea of
scoring fusion is to weight each primary credit network score according to certain influence
factors.
The advanced credit network consists of anchor credit nodes in the three primary credit
networks of A, B and C. In the case of primary credit network A,A represents the total score
of the credit scoring model in network A,a represents the number of scores scored by the
user in the current primary credit network, andP1 represents the converged scoring impact
factor of the primary network. Suppose user W has primary credit scores in the three primary
credit networks A, B, and C, and the final fusion score is divided into M.
α represents the percentage of user scores in the primary credit network. Such as the
percentage of W users' credit scores on network A
α1=a/A。
μ indicates the share of the primary credit network in all primary credit networks that
contain the user. If the three primary credit networks of A, B, and C also contain W users, the
proportion of primary credit network influence factors in the W user fusion score is:
γ represents the converged credit score that the user ends up with, or the final personal
credit score. For example, the W user's final personal credit score is expressed as:
The fusion scoring influence factor of primary credit network needs to be determined
according to the influence of the node entity that makes up the network in the personal credit
system, which usually depends on the market share of individual credit business, platform
credibility and other indicators.
7.Ecosystems and scenarios
7.1 No intermediary borrowing
The POCR Platform Program Enables all previous intermediaries to perform things done
by code by establishing smart contracts, including code to accept and manage deposits, and
code to manage mortgages and issue loans, and when the value of collateral fluctuates, smart
contracts can also execute code to liquidate collateral and return to smart contracts, as agreed
earlier. And these codes, thanks to blockchain technology, cannot be controlled or stopped
by anyone or institution, and they will only be executed in a predefined manner.
MakerDAO and Compound are typical of "no intermediary lending". Their approach is to
create a pool of funds that smart contracts can manage for lending. In today's dollar bank
rates and essentially zero interest rates, if you put your idle, SEC-approved 10,000 digital
dollars into it, the annualized return can be as high as 11.26 percent. When the amount of
money deposited increases, the return will be dynamically smaller, and when the amount
borrowed increases, the return will be dynamically larger. Interestingly, when the smart
contract itself is up and running, even the project parties that developed the smart contract
can't move the money, everything will be executed entirely on the basis of the code, and they
themselves add a percentage of the profits to it as the developer's income.
7.2 No managed transactions
As we all know, in today's financial environment, almost all transactions go through the
centralization of assets or funds, the root cause is the counterparty risk: that is, when you deal
with the other party, how to ensure that you can get the assets or funds you want to exchange.
The same is true for stock trading, real estate trading, or any OTC (over-counter)
transaction. You need to host the assets or funds you want to pay to an institution, as do the
counterparty, and then trade without worrying about the counterparty's risk. The centralized
custodian charges the hosting service fee and transaction service fee in the middle, and
sometimes in the OTC transaction, the fee to be paid to the centralized custodian is as high
as 3%-5%.
While the POCR platform brings us unmanaged transactions that are actually managed
by code (smart contracts or distributed key control management systems, such as Fusion's
DCRM) to accept asset custody by you and the counterparty, the blockchain decentralized
code ensures that the exchange of assets between the two parties is atomic, and when you
close a deal with a counterparty, the assets or funds of the other party are naturally on your
account. This code-executed "unmanaged transaction" costs almost 0.
The POCR team believes that decentralized transactions should focus on unmanaged
decentralized transactions between chains and systems, such as the use of Fusion's distributed
hosting technology to achieve high efficiency and low cost, a huge market, especially OTC
market, its own counterparty risk is hard demand, and its own market volume is much larger
than the over-the-market market, the development prospects are extremely impressive.
7.3 Programmable standardized financial derivatives
The derivatives we see today are basically designed and issued by centralized financial
institutions. For example, bank acceptance bills, bonds, reasoning, options and so on. The
high cost of centralized issuance is not to mention, and it is precisely because these are
designed and issued by central institutions that financial derivatives issued by different
institutions with the same parameters cannot be homogenized.
Through POCR's decentralized code, the blockchain consensus code is issued based
on the underlying asset, so that anyone or organization can make code derivatives based on
the underlying assets, if we set the same parameters, then different people produce financial
derivatives without any difference.
This large market potential is huge, the volume of financial derivatives is actually many
times larger than the money market, in this type of"Defi" decentralized financial technology,
not only make financial derivatives themselves can be interconnected, but also greatly reduce
the original central institutions issued financial derivatives to serve the real business costs, but
also greatly shorten the issuance time.
7.4 Financial process automation
Since the advent of computer technology, more and more things have been digitized,
while processes such as office automation and supply chain automation have been
automated. But financial things have not been fully automated. The root cause is trust, how
can you accept that your money is in someone else's hands and automatically transfer it?
Even if this efficient automation is needed in some business scenarios, we need a central
organization to keep our money safe.
Defi has a strong advantage in this regard, smart contract templates can dynamically
generate flexible smart contracts based on digital signatures of different accounts, the
allocation and collection of accounts, but also according to different conditions to set different
rules. This class has great potential in the to B market. In the future, this category of Defi
customers will be available to companies with numerous branches, institutions with complex
models of collaboration, or even start-ups whose shareholders are spread across different
locations around the world. The cost is also close to 0.
7.5 Integrity Big Data Management and Defi Ecology
The purpose of POCR is to establish a platform system to realize decentralized financial
credit business using integrity big data, the core application of which is to conduct a fair
evaluation of various subjects through the integrity big data in the alliance chain, so that the
financial system can be more efficient, use good faith data to empower Defi ecology, improve
lending efficiency and liquidity income, let Defi gradually step into the science and credit
ecology from the pledge ecology, and thus build a larger PCR POCR decentralized financial
system.
8.The mine pool allocation mechanism
POCR token (ProtocolofConRabbi Token) is the only pass-through for POCR financial
systems, with a total of 180 million issues issued, both on the Ethereum-based BSC chain
and the TRC chain. The maximum output per year decreases over a period of 6 years and is
divided into four mine pools: shared, advanced, Genesis node, and initial team.
The POCR team actively builds the POCR community, always upholds the concept of
community governance and the design of inclusive mining with liquidity mining, and is
committed to creating a Defi system covering all ecological financial services such as trading,
lending, asset synthesis, mortgage, liquidation, etc., and implementing all business logic and
algorithms through smart contracts to ensure fairness, openness and fairness throughout the
life cycle of the system. At the same time, the POCR team has always been user-oriented,
through liquidity mining and other inclusive measures, so that users and decentralized
financial system growth tied, so that users through the POCR community can participate in
the construction of POCR system.
As mentioned above, the total number ofPOCR issues is 180 million, of which 4% is for

community circulation, the community circulation POCR coins are released through the
resonant deflation distribution mechanism, and the sign-off rate increases with the growth of
community contributions;ThePOCR system simultaneously turns on the Defi lending financial
system, allowing both borrowers and borrowers to engage in liquidity mining through
pledges.
Members can use the POCR financial system Defi lending financial system for liquidity
mining, pledge poCR in their account to the platform, borrow OUT USDT, resonate to
subscribe to POCR, or deposit USDT into the platform to earn interest. From a minimum of
100POCR on pledge, you can borrow 1 times the market value of the pledge loan USDT, at
most not more than 80% of the account principal.
Pledge lending time 24 hours, pledge loan period prohibited to withdraw money, transfer,
transfer, etc. , pledge loan time 24 hours after the platform automatically closed positions, the
principal and interest of the loan in the loan account automatically cleared, return pledge
