On Could 20, 2024, Bitcoin Layer 2 improvement group BEVM revealed a technical yellow paper titled “Taproot Consensus: A Decentralized BTC Layer 2 Answer.” The paper particulars the implementation of Taproot Consensus, which leverages native Bitcoin applied sciences equivalent to Schnorr signatures, MAST, and Bitcoin SPV nodes to construct a totally decentralized BTC Layer 2 answer. Taproot Consensus considerably improves native Bitcoin scalability by an revolutionary mixture of current Bitcoin applied sciences with out modifying Bitcoin's core code.

I. Bitcoin's Technical Evolution

• October 31, 2008: Satoshi Nakamoto revealed “Bitcoin: A Peer-to-Peer Digital Money System” and launched the idea of Bitcoin and SPV (Easy Fee Verification).
• January 3, 2009: Nakamoto mined the genesis block and launched Bitcoin. The unique code used ECDSA for digital signatures as an alternative of the extra appropriate Schnorr signatures, which had been underneath patent safety on the time. Schnorr signatures protect all of the performance and safety assumptions of ECDSA and might exceed ECDSA's 15 signature restrict, permitting Bitcoin to be managed with 1000’s of addresses with out impacting signing velocity.
• 2018: Bitcoin core builders have proposed integrating Schnorr signatures into the Bitcoin community.
• November 14, 2021: Taproot’s improve built-in Schnorr signatures and launched MAST (Merkelized Summary Syntax Bushes), enabling sensible contract-like performance and decentralized multi-signature administration.
• BEVM's Taproot Consensus answer builds on these developments, combining Schnorr signatures with MAST to handle multi-signature addresses and allow complicated enterprise eventualities on Bitcoin Layer2.

II. Taproot Consensus Answer Overview:

The Yellow Paper begins by highlighting Bitcoin's non-Turing completeness and restricted sensible contract capabilities. Reasonably than modifying Bitcoin's Layer 1, it argues for constructing a decentralized Layer 2 answer utilizing Bitcoin's current capabilities.

BEVM’s Taproot consensus combines Bitcoin’s Taproot know-how (Schnorr signatures and MAST), Bitcoin SPV Mild Nodes, and the BFT PoS consensus mechanism to create a decentralized and constant Layer 2 community.

III. Detailed Description of the Taproot Consensus Structure

The Taproot consensus structure consists of three essential elements: Schnorr+MAST, Bitcoin SPV, and Aura+Grandpa.

Schnorr+MAST: These applied sciences from the Taproot improve can be used to attain decentralized Bitcoin multi-signature administration powered by the Bitcoin code.

Bitcoin SPV: It permits for the synchronization and validation of Bitcoin transactions with out operating a full node.

Aura + Grandpa: A sophisticated PoS consensus protocol for Byzantine fault tolerance ensures excessive consistency amongst community nodes.

Within the BEVM system, every validator holds a BTC personal key for Schnorr signing. The aggregated public keys kind a MAST tree, enabling BTC transfers and stamping to threshold signature addresses. Validators act as Bitcoin SPV gentle nodes, synchronizing the BTC community state securely and permissionlessly. Aura+Grandpa makes use of belongings managed by BFT consensus to make sure the safety and reliability of the layer-2 community.

The working precept of Taproot Consensus is as follows: “Within the BEVM system, every validator holds a BTC personal key for Schnorr signatures. The properties of Schnorr signatures enable environment friendly signature aggregation, bettering the safety and effectivity of the system. The combination public key Pagg generated by the Musig2 multi-signature scheme varieties a big MAST (Merkle Summary Syntax Tree). After producing the basis hash of the MAST tree, the validator performs BTC switch and stamping to the edge signature tackle generated by the MAST tree, permitting information to be despatched from the BTC mainnet to the BEVM community. Every validator additionally acts as a Bitcoin SPV (Easy Fee Validation) gentle node, permitting it to securely and permissionlessly synchronize the state of the BTC community.”

IV. Different Technical Particulars of the Yellow Paper – True Decentralization

The yellow paper additionally particulars the implementation of Schnorr signatures, MAST, Bitcoin SPV gentle nodes, and Aura+Grandpa, offering a complete technical overview for anybody thinking about Bitcoin know-how. It discusses Musig2's implementation and contrasts it with different BTC Layer 2 initiatives equivalent to Mezo, which additionally use the tBTC protocol. In contrast to tBTC, which depends on a community of 9 signers, Taproot Consensus integrates a multi-signature community with BFT PoS consensus to attain true decentralization.

Moreover, the Yellow Paper describes Musig2's implementation course of and the way it differs from different BTC Layer2 initiatives equivalent to Mezo and Taproot Consensus. Mezo's underlying technical construction is predicated on the tBTC protocol, which makes use of Bitcoin's multi-signatures to construct a threshold signature community, offering stronger consistency in comparison with conventional decentralized networks. Nonetheless, whereas tBTC nonetheless depends on a community of 9 signers, a very decentralized system have to be consensus-driven, combining a multi-signature community with a BFT PoS (Byzantine Fault Tolerant Proof of Stake) consensus mechanism. That is the distinction between a decentralized community and a blockchain. A decentralized community values ​​decentralization however lacks Byzantine Fault Tolerant consensus. However, a blockchain, whereas being a decentralized community, is pushed by Byzantine Fault Tolerant consensus, attaining true decentralization. The Taproot Consensus answer adopts this extra superior design. By integrating Schnorr signatures, MAST, Bitcoin SPV Mild Nodes, Aura and Grandpa Byzantine fault-tolerant consensus mechanisms, we create a constant, safe and decentralized Layer 2 scalability answer. This integration improves the scalability and usefulness of the Bitcoin community and ensures the safety and consistency of the BEVM community.

Conclusion

The BEVM group's technical yellow paper comprehensively describes Taproot Consensus, a Bitcoin Layer 2 answer constructed totally with native Bitcoin know-how. The answer is revolutionary whereas respecting Bitcoin's authentic technical route, making it a real evolution of native Bitcoin scalability know-how. Because the Bitcoin ecosystem evolves, options like Taproot Consensus can be important to its improvement and can function a key basis for a very decentralized Bitcoin Layer 2 answer.
