In order to better connect the Ethereum and Bitcoin ecosystems, the BEVM team is building a relay chain based on OPtimism's OP Stack that uses WBTC as GAS and is compatible with OP-Rollup. This relay chain will serve as a completely decentralized middle layer to introduce mainstream assets on Ethereum (WBTC/ETH/USDC/USDT, etc.) to the BEVM network.

Not only that, the BEVM team has officially made Op-Rollup compatible with the BEVM Stack. In the future, any developer can launch a BTC Layer2 compatible with OP-Rollup based on the BEVM Stack.

OP-Rollup compatible with WBTC relay chain test network activity

At present, BEVM has officially launched the test network of this relay chain and launched a test network experience activity. Users can receive WBTC through the faucet to participate in the test, and can mint the test network NFT to experience the performance of the test network. Users who participate in this activity can get OP tokens and BEVM tokens airdrops.

BEVM-Stack will be fully compatible with OP-Stack and ZK-Rollup

In order to fully integrate the Ethereum ecosystem into the Bitcoin ecosystem, BEVM-Stack will be fully compatible with OP-Rollup and ZK-Rollup.

BEVM-Stack is a protocol that fully modularizes Taproot Consensus, a decentralized BTC Layer2 solution. Currently, BVEM-Stack is compatible with OP-Rollup. In the future, BEVM-Stack will be fully compatible with ZK-Rollup and integrate Madara into the existing BEVM-Stack architecture.

Through the following figure, we can intuitively and comprehensively see the technical architecture of BEVM-Stack:

1. First, through Taproot consensus, a decentralized Bitcoin Layer2 solution is realized. BEVM-Stack modularizes the solution and turns Taproot Consensus into a general solution for BTC Layer2.

2. Then BEVM-Stack is compatible with Op Rollup, introducing Ethereum ecosystem assets into the Bitcoin ecosystem;

3. Finally, BEVM-Stack is compatible with Zk Rollup, fully connecting the Ethereum and Bitcoin ecosystems, allowing assets to flow freely and decentralized between the Bitcoin and Ethereum ecosystems.

At this point, BEVM-Stack will be able to fully open the BTC Layer2 solution compatible with OP Rollup and ZK Rollup, Taproot Consensus, to any group.

Taproot Consensus Upgrade Plan

In addition to the horizontal expansion of the BEVM-Stack solution, the BEVM team also pays close attention to other technical upgrades in the Bitcoin ecosystem, thereby continuously upgrading the Taproot Consensus solution.

The BEVM team noticed that the Bitcoin network has the probability of supporting OP_CAT in the future upgrade of the new BIP, and the team has explored the ZK-STARK technology. ZK-STARK is an advanced zero-knowledge proof technology that can not only verify the correctness of data, but also protect user privacy without exposing transaction details. BEVM's Taproot Concensus is also integrating OP_CAT and ZK-STARK in the test network. Through the integration of the two, BEVM can greatly enhance data privacy and transaction security.

For BEVM, the existing Taproot Consensus solution includes components such as SPV, BFT PoS and Taproot (Schnorr and MAST), as shown in the figure below:

In the new technical architecture, BEVM introduces OP_CAT ZK-STARK to verify and settle all BEVM transactions. After implementation, BEVM transactions can be settled in both Bitcoin and Ethereum. And enhance the security and privacy protection of the network.

Therefore, through improvements, the original solution will be upgraded to the industry's first SPV + BFT PoS + Taproot (Schnorr) + OP_CAT + ZK-STARK. Specifically, the core components of the new solution include:

· SPV (Simple Payment Verification): Simple payment verification, used to verify users' cross-chain transactions from the Bitcoin network and BEVM, ensuring fast and efficient transaction confirmation;

· BFT PoS (Byzantine Fault Tolerance Proof of Stake): This mechanism requires at least 2/3 of the verification nodes to reach a consensus. Turn BEVM into a completely consensus-driven network, improving overall security and efficiency; · Taproot (Schnorr): used to achieve decentralized Bitcoin custody, improving the privacy and efficiency of transactions; · OP_CAT and ZK-STARK: used to verify second-layer transactions through zero-knowledge proof technology and optimized smart contract execution. The integration of these technologies can not only improve the privacy protection and scalability of the network, but also provide new solutions for the interoperability of Bitcoin and Ethereum, and is expected to achieve a more decentralized Bitcoin Layer2 solution. If this technical solution is successfully implemented, it will help Taproot Consensus to reach a new level and will also usher in a comprehensive outbreak of the Bitcoin ecosystem.

Summary

By introducing OP Rollup and ZK Rollup, BEVM will further enrich the functions of BEVM-Stack and promote its integration with the Ethereum ecosystem. The introduction of WBTC as the Gas fee can also bring more vitality and power to the development of the BEVM ecosystem, thereby truly realizing the connection between Bitcoin and Ethereum ecosystems.

Secondly, the optimized Taproot Consensus solution, by introducing OP_CAT and ZK-STARK, can not only improve the scalability and efficiency of the network, but also further reduce transaction costs. This technical advantage will also attract more developers and users, promote the rapid development of the BEVM ecosystem, and provide a new solution for Bitcoin scalability. At the same time, the integration of these technologies realizes the privacy protection of transaction data and ensures the authenticity and validity of transactions.

Finally, BEVM will further promote the development of DeFi through seamless connection with Ethereum and multi-chain interoperability. Users can conduct more efficient and secure decentralized financial transactions on the BEVM network and enjoy more financial services and innovative applications. By being compatible with a variety of blockchain technologies and platforms, BEVM will attract more ecological projects and partners to jointly promote the development and application of the Bitcoin ecosystem.

Therefore, by integrating OP Rollup and ZK Rollup, introducing WBTC as the Gas fee, and optimizing the Taproot Consensus solution with the help of OP_CAT and ZK-STARK, the security, privacy protection and scalability of the BEVM network will be greatly improved. In the future, with the continuous optimization of technology and the continuous expansion of the ecosystem, BEVM is expected to release more vitality in the Bitcoin ecosystem and bring more breakthrough growth opportunities to the industry.
