Taproot Consensus is currently the most native and decentralized BTC L2 solution.
TAPROOT CONSENSUS is a BTC L2 solution based on Bitcoin’s native technology. The core components are Schnorr Signature, Mast Contract, SPV Node Network (full name Bitch Simplify Payent Verify Node N etWork)
Among them, Schnorr Signature and Mast Contract are the core technologies of the Bitcoin network introduced by Taproot upgrades in 2021; SPV Node Network, also known as simple payment verification node network, is the network composed of Bitcoin light nodes.The simple payment verification scheme explained in Section 8.It means that even if some nodes (Bitcoin light nodes) do not have a complete transaction record, it can be convenient and safely verifying the payment method.
So,How does taproot consensus work?
First of all, Schnorr Signature (that is, Schino’s signature) can expand the multi -signal address of Bitcoin to 1,000, that is, 1,000 Taproot wallet addresses can jointly manage the same BTC assets, and can ensure efficiency, security and privacy.Traditional Bitcoin -based Bitcoin -based signatures of elliptical curves can only be 15 addresses, while Schnorr Signature can achieve sufficient dispersion of multi -signal address.
However, it is not enough to realize the decentralization of multiple signing addresses. It must also achieve the automation and intelligence of the signature, that is, the code is driven to achieve code -driven, and it cannot be signed by others.
Imagine that if a BTC L2, the address of its hosting Bitcoin requires a group of people to sign one by one to execute and cross out. How is its efficiency low?How to guarantee its safety?
Therefore, after the decentralization of the multiple -signed address, Mast Contract must be introduced to achieve the automation and codeization of the signature.
Mast Contract is also one of the core technologies introduced by Bitcoin Taproot. The full name of Mast Contract is Merkle Abstract Syntax Tree Contract, that is, the Merkel abstract syntax contract.A script that does not overlap (for example, multiple signatures or time locks).When spending, you only need to disclose the relevant script and the path from the script to the root of the Merck tree.It can be simply understood that the Mast Contract is a smart contract that can handle multiple -sign payment on the Bitcoin chain (although it is different from the smart contract of Ethereum, it can be used on the Bitcoin Schinolo signing that can play a smart contract.Effect)
With MAST, you can realize the intelligence, automation, and codeization of Schonor’s signature, that is, the concept of multiple signatures is killed here, and the code instruction is replaced.This is a very important point.
So who will send instructions?A instructions are issued by SPV Node Network.
That is, a network consisting of Bitcoin light nodes running on the BTC 2nd layer network.Relying on the BFT network consensus to drive the Mast Contract instructions, it is not driven by any organization or person, which realizes completely decentralization.Why use SPV Node Network (Bitcoin light node network) instead of ordinary POS node networks?Because Bitcoin light nodes can synchronize the first layer of data of Bitcoin and have no complete transaction records, it can also be convenient and securely verified with payment, that is, SPV (SIMPLIFied Payment Verification).
Summary:
SCHNORR SIGNATURE allows Bitcoin to sign more addresses to 1,000 to achieve decentralization of multi -signal address.
MAST CONTRACT realizes the codeization of multiple signing management. It does not rely on people to sign, but relies on code drive.
SPV Node Network realizes the consensus of the Bitcoin light node network consensus to drive more signatures, fully realized the decentralized Bitcoin cross -chain and management.
Taproot Consensus = SCHNORR SIGNATURE+MAST CONTRACT+SPV Node Network. This is currently the most native and decentralized BTC L2 solution.
The earliest proposed Taproot Consensus and creatively applied to the BTC L2 practice is the BEVM team. Since 2018, the team has launched a BTC L2 solution based on SPV Node Network and achieved 100,000+BTC cross -chain, 500,000+BTC Hash Lock;After the Bitcoin Taproot upgrade in 2021, combined with Schnorr Signature+Mast Contract, it proposed the BTC L2 solution of Taproot Consensus and launched BEVM in May 2023, realizing the complete practice and landing of Taproot Consensus.In addition to BEVM, the BTC L2-Bitfinity currently hatched by the ICP Foundation also uses similar solutions.
It is reported that,BEVM will modular the Taproot Corsensus solution, and after the main network is launched, the BEVM-Stack is supported by the one-click BTC L2 of any team. At the same time, To combine the strength of all parties to jointly build and enrich the Bitcoin ecosystem.
