BEVM Unveils Groundbreaking Taproot Consensus for Decentralized Bitcoin Layer 2 Solution

Cardiff, 英国, Might twenty sixth, 2024, Chainwire

On Might 20, 2024, the Bitcoin Layer2 improvement workforce BEVM launched the technical yellow paper titled “Taproot Consensus: A Decentralized BTC Layer2 Solution.” This paper particulars the implementation of Taproot Consensus, leveraging native Bitcoin applied sciences reminiscent of 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 Electronic Cash System,” introducing Bitcoin and the idea of SPV (Easy Cost Verification).
  • January 3, 2009: Nakamoto mined the Genesis Block, launching Bitcoin. The unique code used ECDSA for digital signatures as a substitute of the extra appropriate Schnorr signatures, which had 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 Bushes), 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 eventualities in Bitcoin Layer2.

II. Overview of the Taproot Consensus Solution:

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 quite than modifying Bitcoin Layer1.

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 Layer2 community.

III. Detailed Clarification of Taproot Consensus Structure

The Taproot Consensus structure includes three principal 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 kinds a MAST tree, enabling BTC transfers and inscriptions to the edge signature handle. 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 property managed by BFT consensus.

The working precept of Taproot Consensus is: “In the BEVM system, each validator holds a BTC private key for Schnorr signatures. The characteristic of Schnorr signatures enables efficient signature aggregation, thereby enhancing the system’s security and efficiency. The aggregated public key Pagg, generated through the Musig2 multi-signature scheme, forms a large MAST (Merkle Abstract Syntax Tree). After generating the root hash of the MAST tree, validators perform BTC transfers and inscriptions to the threshold signature address generated by the MAST tree, enabling the submission of data from the BTC mainnet to the BEVM network. Each validator also acts as a Bitcoin SPV (Simplified Payment Verification) light node, allowing them to securely and permissionlessly synchronize the BTC network 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 all for Bitcoin applied sciences. It explains the Musig2 implementation and contrasts with different BTC Layer2 initiatives 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, reaching true decentralization.

Furthermore, the yellow paper explains the implementation strategy of Musig2 and the variations between different BTC Layer2 initiatives 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. Nevertheless, tBTC nonetheless depends on a community of 9 signatories, whereas a really decentralized system ought to 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, reaching 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 usefulness of the Bitcoin community and ensures the safety and consistency of the BEVM community.


The BEVM workforce’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 unique technological route, making it a real evolution of native Bitcoin scalability know-how. Because the Bitcoin ecosystem evolves, options like Taproot Consensus can be essential for its improvement, serving as main cornerstones for actually decentralized Bitcoin Layer2 options.
