1. Project introduction

In the era of artificial intelligence that has already begun, the development of technologies such as big data, cloud computing, the Internet of Things, robots, 5G communications, and blockchain all point to artificial intelligence. Gradually began to land in various industrial fields. In addition to Hash computing power applied in the field of encrypted digital currency, various new computing power such as complex genetic computing power for biomedical engineering, IPFS computing power for distributed storage, and AI computing power based on big data are constantly emerging. The demand for computing power resources in all walks of life will also become more and more. At the same time, mankind is entering the era of "data monopoly" and "computing resource monopoly". Computing power is gradually showing a trend of centralized monopoly. It will pose a huge threat to human society.
In order to break the monopoly of computing power, ensure human security in the era of machine intelligence, and solve the imbalance between supply and demand between computing power suppliers and users, the supply, management, transaction, and Delivery, clearing, and derivative financial services all urgently need a decentralized, intelligent, neutral blockchain network that does not belong to any person or organization. Introduce the rights and interests of power holders and producers into a new consensus mechanism, and then use technologies such as smart contracts, side chains, and cross-chains to expand the computing power ecosystem, and provide "connectivity", "transfer," Credit" and other services, to create a sustainable, secure, and trustworthy decentralized computing power infrastructure, so that everyone can easily share the computing power dividend in the AI ​​​​era.

Fourth, technical overview

Computing power routing model:
The chaining of assets in the real world is to establish a digital model through effective confirmation and measurement of the right to use and ownership of assets, and convert them into programmable on-chain For digital assets, we call this process virtualization of computing power, that is, digitization of computing power assets. The virtualization process of each new computing power is the process of generating a new side chain by slicing the main chain. The real-time delivery, transfer, and extraction of computing power on the side chain requires a transparent and credible access link point, and this link point is called "computing power routing". The mechanism of computing power routing is actually the mechanism of computing power on the chain. The delivery process of computing power between producers and users is the switching process of "computing power routing". As long as the multi-source heterogeneous computing power is measurable and divisible, the multi-source heterogeneous computing power quantization model can be adopted to be certified in the BHP computing power network to complete the confirmation of asset rights and realize the transfer of use rights. Circulation in the BHP computing power network.

Blockchain technology architecture:
The BHP blockchain technology architecture includes from bottom to top: the bottom data layer, asymmetric encryption and hash function combining public and private keys To ensure that information is not tampered with, chain storage structure, time stamp, Merkle number and other technologies; the network layer mainly includes P2P network, transaction broadcast and transaction verification mechanism; the core consensus layer solves the consensus of distributed systems The consensus mechanism is the proof-of-stake mechanism PoS; the issuance mechanism and incentive mechanism in the incentive layer are the product of the combination of economics and distributed computing, allowing highly dispersed nodes to consciously participate in system maintenance and construction; the contract layer is composed of Smart contracts run virtual machines, contract execution engines, consensus algorithms, and contract script codes that can be deployed; the application layer encapsulates various application scenarios of the blockchain, such as user interaction interfaces, smart contract APIs, software and hardware wallets, and multi-chain wallets Various blockchain applications built on the blockchain, such as cross-border payment systems, etc., programmable finance and programmable society will also be built on this layer.

Intelligent sharding network:
Improving network transaction throughput can use block expansion and horizontal expansion. BHP public chain adopts independent dynamic sharding technology based on intelligent load balancing to realize block The horizontal expansion of the chain. Each shard can process different transactions at the same time, and the processing performance of the entire network has been improved linearly. In each cycle, the system randomly forms nodes into a shard, and the nodes in the shard only verify their respective transactions, and broadcast the verification results to the main chain to help the main chain finalize the block. Each node in the smart sharding network stores the distributed ledger of the main chain.

Block transaction model:
In the BHP payment system, a block is generated every 15 seconds on average, and the block consists of a block body and a block header. The block body is mainly the transactions generated in this time period, and the block header includes the hash value Hr-1 of the previous block, the Merkle tree root hash MerkleTX composed of the current transaction, the timestamp T and the random number Nonce, etc. Since the block header contains the hash value pointing to the previous block, the blocks form a "chain"-like structure.
The BHP blockchain ledger is consistent with the principle of Bitcoin. BHP uses the unspent transaction output (UXTO) model instead of traditional accounts. The UXTO system abides by two rules:
(1) In addition to mining transactions, all sources of funds must come from UXTO of one or several previous transactions;
(2) The total input of any transaction The amount must be equal to the total output, and both sides of the equation must be equal. (Generally, the output is less than the input, and the difference is the transfer fee, which belongs to the PoS miners.)
The biggest advantage of the UXTO model is that it can faithfully record transactions. Our real world flows with time, transactions happen one by one, and the blockchain system faithfully records what happened in this world one by one, which cannot be rolled back or deleted.

Smart contract system:
BHP has an independent smart contract system: BHPContract. It is a micro-core, platform-independent smart contract execution environment, providing a set of instruction sets including stack operations, process control, logical operations, arithmetic operations, cryptographic operations, string operations, and array operations. In terms of hardware, it Only two compute stacks are provided. However, because it allows the implementers of the blockchain to create their own virtual hardware and open it to smart contracts in the form of interfaces, the contracts can obtain platform-related data, persistent storage, and access to the Internet at runtime. Although this may also make the behavior of the contract uncertain, the implementor of the blockchain can eliminate this uncertainty by properly programming the virtual hardware. However, since there is no compiler and development environment for AVM at present, this makes it very difficult to develop smart contracts based on AVM. Developers have to use a syntax similar to assembly to write contracts, which requires high technology. ability.
BHP smart contract runs in BhpVM with high certainty, high concurrency and high scalability. According to the design goals of the BHP computing power public chain, the smart contracts that users can realize based on BHPContract include: deposit interest contracts, credit mortgage contracts, commercial payment contracts, remittance transaction contracts, asset investment contracts, etc. In the future, with the continuous upgrading of the smart contract protocol, the BHP computing power public chain will support users to develop more smart contracts.

Cross-chain exchange protocol:
BHP is a distributed network that supports multi-side chain associations, supports the "computing power main chain + high-performance multi-side chain" architecture, and can realize multi-asset exchange efficient exchange between them. BHP's protocol for cross-chain interoperability consists of two parts: "Cross-chain asset exchange protocol" and "Cross-chain distributed transaction protocol".
(1) Multi-chain atomic asset exchange protocol
BHP has expanded on the double-chain atomic asset exchange protocol, which allows multiple participants to exchange assets on different blockchains and guarantees the entire transaction process All of the steps in either all succeeded or all failed. In order to realize this function, we will use the function of smart contract to create a contract account for each participant. The exchange of respective digital assets can be realized across two completely unrelated blockchains.
The multi-chain atomic asset exchange protocol will not add complex communication mechanisms between chains, but it can ensure that this exchange is atomic and credible, and there will be no transfer of equity but no transfer of creditor's rights .
(2) Cross-chain distributed transaction protocol
Cross-chain distributed transaction means that multiple steps of the transaction are distributed and executed on different blockchains, and the consistency of the entire transaction is guaranteed. This is an extension of cross-chain asset exchange, extending the behavior of asset exchange to arbitrary behavior. BHP will adopt cross-chain smart contracts. A smart contract can execute different parts on multiple different blockchains, either all of them are executed, or they are all returned to the state before execution.

V. Comments

Through the mixed entrustment consensus mechanism of computing power holders and BHP holders, the BHP intelligent computing power network introduces computing power holders into the governance structure, and the computing power rights and interests of BHP holders are bound to each other , Mutual restriction, to realize the transmission of computing power credit to the BHP public chain. In essence, the BHP public chain is a decentralized blockchain network with computing power as credit endorsement and smart contracts.

The BHP Alliance is an independent, not-for-profit membership organization whose purpose is to coordinate and provide the BHP governance network framework, sustain and lead social impact funding. The members of the alliance consist of a network of verification nodes running the BHP public chain. Members of the BHP Alliance will include diverse businesses, non-profit and multilateral organizations and academic institutions located in various locations.

In addition, the BHP public chain will be open to everyone: any consumer, developer or business can use the BHP network, build products on it and add value to their services. Open access ensures low barriers to entry and innovation, and encourages healthy competition among interested audiences.
