Amid the rapid development of blockchain technology, an increasingly prominent issue is how to achieve effective censorship resistance in an environment that relies on consensus mechanisms. Traditional blockchains are mostly driven by leaders, which gives leaders too much power over transaction selection and ordering, leading to potential censorship risks. This risk not only threatens the transparency and fairness of blockchains, but also limits its widespread application as a decentralized platform. It is against this background that Braid came into being, aiming to solve the censorship resistance problem in Ethereum.

Censorship resistance is of great significance to the healthy development and widespread application of blockchain technology. First, it is the cornerstone of ensuring the transparency and fairness of blockchains. The immutability and transparency of blockchains are their core values, and censorship is a direct threat to this value. Secondly, censorship resistance is also a reflection of the decentralized nature of blockchains. By achieving censorship resistance, Ethereum can truly become a decentralized network platform that is not controlled by a single entity, providing support for more users and applications.

Braid aims to build an Ethereum system that can resist censorship. It is currently in its early stages, but has demonstrated its unique design ideas and technical potential. The core concept of Braid is to break the monopoly control of Ethereum by a single leader through technical means such as multi-block parallelism and synchronous release, thereby ensuring the free flow of transactions and the fairness of the Ethereum network.

The design principles of Braid mainly include key elements such as multi-proposer model and synchronous release. The multi-proposer model increases the cost of transactions being blocked by introducing multiple concurrent proposers, thereby improving Ethereum's censorship resistance. Synchronous release ensures that all proposers act simultaneously on the same set of information, further enhancing the fairness and transparency of the system. In addition, Braid also adopts strategies such as delayed execution to allow multiple proposers to influence the transaction status, further ensuring the stability and reliability of the Ethereum network.

In comparison with existing solutions, Braid has demonstrated its unique advantages. In the LMD-Ghost (Latest Message Driven Ghost) consensus mechanism with multiple proposers, it may be necessary to store high branching factor trees in the local view to solve the fork choice problem. Although the Mysticeti (Sui) solution is about to be put into production, it has certain limitations in elegantly managing the number of validators. Compared with solutions such as LMD-Ghost and Mysticeti (Sui), Braid not only achieves stronger censorship resistance, but also retains the transparency and fairness of Ethereum. At the same time, Braid's design is more concise and efficient, reducing the difficulty and cost of implementation. These advantages make Braid a strong candidate for solving Ethereum's censorship problem.

In the specific implementation, Braid adopts a multi-block parallel approach and uses the same consensus mechanism to ensure consistency and collaboration between these chains. By running multiple parallel blocks, Braid achieves decentralized and decentralized transaction processing, thereby effectively resisting censorship risks. At the same time, Braid has also developed a technical tool called "finality device" to complete the final processing of transactions. This tool ensures the finality and consistency of transactions by extracting the transaction consortium on all chains and reordering these transactions.

Compared with traditional blockchain design, Braid has significant advantages. First, it achieves stronger anti-censorship capabilities and guarantees the transparency and fairness of Ethereum. Second, Braid's design is more concise and efficient, reducing the difficulty and cost of implementation. These advantages make Braid have a wide range of application prospects in the future. For example, in areas such as auctions that require a high degree of transparency and fairness, Braid can be used as an ideal solution to provide support.

When Ethereum founder Vitalik reposted Braid's tweet, he said: "It's exciting to see such progress! The issue of block construction seems to be gradually approaching its bright prospects."

Indeed, every technological breakthrough and theoretical innovation is a solid step towards a more ideal and decentralized blockchain world. We look forward to Ethereum overcoming all challenges and leading the blockchain industry to a brighter future with the deepening of research and the iteration of technology.
