At the beginning of 2023, based on Bitcoin's SegWit and Taproot upgrade, Ordinals theory was released. Ordinal theory concerns itself with Satoshis, giving them individual identities and allowing them to be tracked, transferred, and imbued with meaning. Individual Satoshis can be inscribed with arbitrary content, creating unique Bitcoin-native digital artifacts that can be held in Bitcoin wallets and transferred using Bitcoin transactions. Inscriptions are as durable, immutable, secure, and decentralized as Bitcoin itself. Then based on Ordinals theory, some innovative protocols appeared on Bitcoin network, represented by BRC-20, Bitcoin NFT and ORC-20, the innovation of the protocols finally extended to the Bitcoin network, creating unlimited imagination space for the future development of Bitcoin ecosystem.

However, as we all know, Bitcoin network has some problems, such as: poor scalability, high transaction fee, and no Turing Complete virtual machine, etc. Besides the problems of Bitcoin itself, the biggest problem of BRC-20 and other new Bitcoin protocols is: centralized, relying on the computing and index of centralized servers. The new Bitcoin protocols have the disadvantages of centralized, censorable, private, and unverifiable, etc. It is impossible to build a completely decentralized Web3 application based on them. And it is urgent to expand Bitcoin protocols in a decentralized way and build decentralized infrastructure for a new era of Bitcoin.

At this time, Biop is created. Biop's vision is to build a truly decentralized infrastructure for Bitcoin ecosystem, so that all Bitcoin-based Web3 applications can be running fast, efficiently and safely based on the Biop in a decentralized manner, do not rely on the centralized server.

The goal of Biop is to solve the centralization of the current Bitcoin extension protocols like BRC-20, as well as poor scalability, high transaction fee, and no Turing Complete virtual machine of the Bitcoin network itself. Biop will implement the Optimistic rollup protocol to expand the scalability of Bitcoin, will run Bitcoin L2 in a decentralized, low-cost, efficient, Turing Complete manner, will help Bitcoin build a much larger decentralized ecosystem and attract much more users to participate. Biop will make the current popular Inscriptions, Ordinals, BRC-20, Bitcoin NFT, ORC-20 and other protocols to obtain decentralized support, and no longer require the support of centralized mechanism off the Bitcoin network, which is much safer and more reliable.

Biop is a safe, fast, smart and low-cost Bitcoin L2 blockchain based on Optimistic rollup protocol built by Bitcoin developers, for Bitcoin developers. To establish a large Bitcoin decentralized ecosystem like DeFi, NFT, GameFi, SocialFi... by BVM and smart contract.

Biop will have 3 versions, all of which are Bitcoin L2 Blockchain based on Optimistic rollup protocol. The first version V1 will focus on solving the centralized problem of Bitcoin protocols such as Ordinals and BRC-20, and will build a decentralized computing L2 blockchain for Bitcoin; V2 will implement the interactive operation of BRC-20 and other protocols based on V1, and will become a complete Bitcoin L2 blockchain, with more than 10,000 TPS, second-level block generation time, based on Bitcoin's decentralization, security, and liquidity; V3 will integrate Ethereum L2, become the world's first L2 Blockchain based on both Bitcoin and Ethereum, share the security, decentralization and liquidity of Bitcoin and Ethereum, establish a super-large ecosystem.

This whitepaper focuses on Biop V1, which will complete the computing for various protocols extended from the Bitcoin network in a decentralized, safe, and reliable manner, will parse the computing results into Biop's Merkle Tree and smart contract to provide query and verification service, and will become the decentralized infrastructure for various ecosystem projects based on new Bitcoin protocols.
