BEVM Unveils Groundbreaking Taproot Consensus for Decentralized Bitcoin Layer 2 Answer

[PRESS RELEASE – Cardiff, 英国, May 26th, 2024]

On Could 20, 2024, the Bitcoin Layer2 improvement group BEVM launched the technical yellow paper titled “Taproot Consensus: A Decentralized BTC Layer2 Answer.” This paper particulars the implementation of Taproot Consensus, leveraging native Bitcoin applied sciences equivalent to Schnorr signatures, MAST, and Bitcoin SPV nodes to construct a totally decentralized BTC Layer2 resolution. Taproot Consensus represents a big leap in native Bitcoin scalability, combining current Bitcoin applied sciences innovatively with out modifying Bitcoin’s core code.

I. Historical past of Bitcoin’s Technical Iterations

• October 31, 2008: Satoshi Nakamoto revealed “Bitcoin: A Peer-to-Peer Digital Money System,” introducing Bitcoin and the idea of SPV (Easy Fee Verification).
• January 3, 2009: Nakamoto mined the Genesis Block, launching Bitcoin. The unique code used ECDSA for digital signatures as an alternative of the extra appropriate Schnorr signatures, which have been below patent safety on the time. Schnorr signatures retain all of the functionalities and safety assumptions of ECDSA and might surpass the 15-signature restrict of ECDSA, enabling the administration of Bitcoin with 1000’s of addresses with out affecting signing pace.
• 2018: Bitcoin core builders proposed integrating Schnorr signatures into the Bitcoin community.
• November 14, 2021: The Taproot improve built-in Schnorr signatures and launched MAST (Merkelized Summary Syntax Timber), enabling good contract-like capabilities and decentralized multi-signature administration.
• The Taproot Consensus resolution by BEVM builds on these developments, combining Schnorr signatures and MAST to handle multi-signature addresses and allow complicated enterprise situations in Bitcoin Layer2.

II. Overview of the Taproot Consensus Answer:

The yellow paper begins by highlighting Bitcoin’s non-Turing full nature and restricted performance for good contracts. It argues for utilizing Bitcoin’s current capabilities to construct a decentralized Layer2 resolution moderately than modifying Bitcoin Layer1.

BEVM’s Taproot Consensus combines Bitcoin’s Taproot expertise (Schnorr signatures and MAST), Bitcoin SPV mild nodes, and the BFT PoS consensus mechanism to create a decentralized and constant Layer2 community.

III. Detailed Rationalization of Taproot Consensus Structure

The Taproot Consensus structure includes three essential parts: Schnorr+MAST, Bitcoin SPV, and Aura+Grandpa.

· Schnorr+MAST: Makes use of these applied sciences from the Taproot improve to realize decentralized Bitcoin multi-signature administration pushed by Bitcoin code.

· Bitcoin SPV: Permits synchronization and verification of Bitcoin transactions with out operating a full node.

· Aura + Grandpa: Superior PoS consensus protocols for Byzantine fault tolerance, making certain excessive consistency amongst community nodes.

Within the BEVM system, every validator holds a BTC non-public key for Schnorr signatures. The aggregated public key types a MAST tree, enabling BTC transfers and inscriptions to the brink signature deal with. Validators act as Bitcoin SPV mild nodes, synchronizing the BTC community state securely and permissionlessly. Aura+Grandpa ensures the Layer2 community’s safety and trustworthiness, with belongings managed by BFT consensus.

The working precept of Taproot Consensus is: “Within the BEVM system, every validator holds a BTC non-public key for Schnorr signatures. The attribute of Schnorr signatures permits environment friendly signature aggregation, thereby enhancing the system’s safety and effectivity. The aggregated public key Pagg, generated via the Musig2 multi-signature scheme, types a big MAST (Merkle Summary Syntax Tree). After producing the basis hash of the MAST tree, validators carry out BTC transfers and inscriptions to the brink signature deal with generated by the MAST tree, enabling the submission of knowledge from the BTC mainnet to the BEVM community. Every validator additionally acts as a Bitcoin SPV (Simplified Fee Verification) mild node, permitting them to securely and permissionlessly synchronize the BTC community state.”

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

The yellow paper additionally particulars the implementation of Schnorr signatures, MAST, Bitcoin SPV mild nodes, and Aura+Grandpa, offering a complete technical define for these interested by Bitcoin applied sciences. It explains the Musig2 implementation and contrasts with different BTC Layer2 tasks like Mezo, which makes use of the tBTC protocol. Not like tBTC, which depends on a community of 9 signatories, Taproot Consensus integrates multi-signature networks with BFT PoS consensus, attaining true decentralization.

Furthermore, the yellow paper explains the implementation technique of Musig2 and the variations between different BTC Layer2 tasks like Mezo and Taproot Consensus. Mezo’s underlying technical construction relies on the tBTC protocol, which makes use of Bitcoin multi-signature to assemble a threshold signature community, providing robust consistency in comparison with conventional distributed networks. Nonetheless, tBTC nonetheless depends on a community of 9 signatories, whereas a very decentralized system must be consensus-driven, combining multi-signature networks with BFT PoS (Byzantine Fault Tolerance Proof of Stake) consensus mechanisms. That is the distinction between distributed networks and blockchains; distributed networks emphasize distribution however lack Byzantine fault-tolerant consensus, whereas blockchains, whereas additionally being distributed networks, are pushed by Byzantine fault-tolerant consensus, attaining true decentralization. The Taproot Consensus resolution adopts this extra superior design. By integrating Schnorr signatures, MAST, Bitcoin SPV mild nodes, and Aura and Grandpa Byzantine fault-tolerant consensus mechanisms, it constructs a extremely constant and safe decentralized Layer2 scalability resolution. This integration enhances the scalability and value 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 Layer2 resolution constructed completely on native Bitcoin applied sciences. It respects and innovates on Bitcoin’s authentic technological course, making it a real evolution of native Bitcoin scalability expertise. Because the Bitcoin ecosystem evolves, options like Taproot Consensus can be essential for its improvement, serving as main cornerstones for really decentralized Bitcoin Layer2 options.
