Detailed introduction
Merlin Chain: Based on ZKEVM technology, TVL is currently the highest
The emergence of Merlin Chain marks the birth of a new BTC L2 solution, which aims to improve the scalability, transaction efficiency and security of the BTC network through a series of technological innovation, while solving network congestion.As a ZK Rollup BTC L2 network, Merlin Chain not only supports a variety of native Bitcoin assets, but also compatible with EVM, showing the design concept of both Bitcoin and Ethereum ecology.
Merlin Chain’sThe core of the technical framework lies in the account system of the chain-agnostic and the BTC Connect technology provided by the Particle Network.These innovations are not only promotedSeamless mapping between BTC and EVM addressIt also brings users a highly efficient and secure cross -chain interactive environment.With a number of technical means such as smart contracts, signature abstraction, and decentralized prophecy machines, Merlin Chain can realize the fast bridge connection and transaction processing of native assets, thereby ensuring the overall safety and credibility of the ecosystem.
Merlin Chain has developed the ZKEVM Layer2 solution based on the Polygon CDK framework. It cleverly uses ZK-Rollup technology to effectively compress and verify a large amount of transaction data, which greatly improves the scalability of transaction processing speed and network scalabilityEssenceBy integrated sequence nodes, Merlin Chain can handle more transaction volume.The compression data, ZK status root and proof generated by ZKEVM technology, uploaded to the L1 Taproot of Bitcoin through the decentralized prophet network security, enhance the overall transparency and security of the network.
Under the technical architecture of Polygon CDK, Merlin Chain uses a solution called CDK Validium. This solution combines Polygon ZKEVM technology and DAC conceptsThe validity verification of multiple signing forms on Ethereum chain is aimed at Ethereum chain.This multi -signing method BTC’s Taproot technology echoed, so the decentralized prophecy on Merlin Chain has essentially the function of DAC.Merlin Chain’s sorter task is to collect user transaction data. After packaging and verification, it is processed by ZKP (zero-knowledge certification) polymer and ProVer. This process is supported by Lumoz’s ZK-POW function.Through the decentralized prophecy network, the transaction data of these L2, including hash and signature, were transmitted to the BTC network.
Through such a technical layout, Merlin Chain realizes a safe and efficient cross -chain interaction method that allows BTC’s L1 and ZKEVM -based L2 solutions to be seamlessly connected.This structure not only strengthens the security and transparency of the network, but also opens up new possibilities for the interoperability between Bitcoin and other blockchain ecosystems, which greatly improves the overall performance and user experience of the system.
Merlin Chain has established interconnection with more than 40 public chains, simplifying the experience of not familiar with users in BTC, allowing them to use familiar wallets (such as Metamask) and assets for interaction.at the same time,Merlin is the only self -developed BTC cross -chain bridge, Support BTC, BRC-20, BRC-420, Bitmap, Ordinals, will soon support Atomicals, STAMP, and Runes later, and also support assets such as ETH, Arbitrum, MANTA, TRON.
B² Network: Using a double -layer structure, the first network to implement ZPVC Rollup
Also as BTC L2, B b Network is introduced by ZKP Rollup technology.This technology aims to improve the speed of transaction processing and expand the diversity of application scenarios, and the achievements of all this are not at the cost of sacrificing security.B² Network became the first network to implement zero -knowledge certification commitment (ZPVC) Rollup on BTC.By adopting the challenge of ZKP and Taproot-response mechanism, it not only supports Turing’s complete smart contracts, but also ensures the privacy and security of transactions.
And this so -called ZPVC uses ZKP to enhance the security and efficiency of BTC Layer 2.Through ZPVC, Bt Network can use a challenge mechanism to ensure the authenticity and integrity of the transaction through a challenge mechanism without directly verifying each proof, thereby using the security consensus of BTC.This method not only improves the efficiency of handling transactions, but also maintains the decentralization characteristics and security of the network.
The B² Network architecture is divided into two main levels: the Rollup layer and data availability (DA) layer.
The ROLLUP layer consists of a variety of components, including account abstraction, RPC service, MEMPOOL, sorter, ZKEVM, polymer, synchronizer and proof generator.This layer is responsible for receiving, storing, sorting, and processing user transactions, and verify the authenticity of the transaction by generating ZKP.This series of steps not only guarantee the security of the transaction, but also ensure the availability of the data, so that developers can build secure DAPPs on the B² network, including DEFI, NFT, etc., and support the migration of DAPP from other EVM compatibility chains to B² networkEssence
The DA layer includes decentralized storage, B² nodes, and BTC networks. It is mainly responsible for permanent storage of ROLLUP data copy, verifying the ZKP of Rollup, and final confirmation on the BTC network.Decentralization storage ensures the durability and accessability of the data; B² nodes perform various network operations, such as verification, sorting and data packaging; the BTC network is responsible for the final confirmation of the transaction to ensure the security and irreversible system of system.These three parts of the work have greatly improved the efficiency and scalability of the network, while retaining the essence of its decentralization.
BEVM: Realize decentralization through Taproot consensus, compatible with Ethereum ecological DAPP
BEVM (Bitcoin Ethereum Virtual Machine) is a decentralized decentralization based on Taproot, EVM is compatible with BTC Layer 2 solutions.It allows BTC as a GAS of transactions, and allows DAPP in the Ethereum ecosystem to run on the BTC network, bringing a wider application scenario to BTC.
In terms of technical architecture, BEVM creates a decentralized BTC L2 solution through Taproot consensus, combining Bitcoin’s native Taproot technology stack and BFT POS network composed of Bitcoin SPV nodes.Taproot consensus consists of three parts: TAPROOT technology (including Musig2, Schnorr signature, MAST, etc.), a BFT POS network composed of Bitcoin SPV, and threshold nodes formed by the SIGNAL protocol.This architecture improves the scalability and privacy of the Bitcoin network. At the same time, the batch verification processing of BEVM technology is improved to improve the efficiency of Bitcoin network transactions.
Schnorr’s signature provides a more efficient and more private signature method that allows aggregation of multiple signatures to reduce transaction size and costs.MAST improves the privacy and efficiency of smart contracts. By allowing the deployment of contracts containing multiple execution paths on the blockchain, it only needs to disclose the data of the actual execution path, thereby improving the privacy and scalability of the data.These technologies have jointly improved transaction efficiency and privacy protection on BEVM.In addition, BEVM uses BTC light nodes as verification nodes, relying on network consensus to achieve the management and use of BTC, thereby achieving true decentralization.The block generation node of the BEVM network is also used as the monitoring node of the Bitcoin main network. The transaction is automatically executed through the network consensus to ensure the security and decentralization of the BTC management and cross -chain process.
In order to simplify the startup and running process of the Bevm node, the Bevm provides an intuitive and simple node deployment process through the Spheron service.Users can easily recharge the SPHERON wallet, select BEVM test nodes, configure recommendation resources and new wallet addresses, etc., so as to ensure the smooth deployment and efficient operation of the node.
BOUNCEBIT: Double Pride POS Consensus Mechanism
