Web3 Barometer: Block Building Market on Solana, BTC-Driven Programmability, and Multi-Dimensional Fee Market Proposal for Ethereum

Jito BAM - Block Sorting and Building Market on Solana

The Jito ecosystem has launched the BAM platform, aimed at achieving more orderly transaction ordering for Solana, combating MEV, and preventing centralization risks. BAM pre-sorts the transactions of the entire block through a trusted execution environment (TEE) and hands it back to the validators. The system supports plugin functionality, allowing specific rules to be "hard-coded" into the transaction ordering to meet the needs of projects like oracles.

Although BAM has strong lineup support and good storytelling, it still faces challenges to become a mainstream market path. The high cost of TEE and its limited performance make it difficult to meet Solana's high throughput requirements. Without continuous economic incentives, the project is unlikely to achieve positive returns. However, BAM may become a valuable tool in certain scenarios, such as providing certainty assurance for critical blocks.

BRC 2.0 - BTC-driven Programmability

BRC 2.0 is a "BTC-driven, EVM-executed" dual-chain shadow system. Users write instructions on BTC, which are executed by a modified version of the EVM in the indexer for corresponding deployments and calls. This system achieves user control by mapping BTC addresses to virtual EVM addresses.

BRC 2.0 continues the idea of adding Programmability to BTC, but faces some risks and challenges. Although the name maintains the volume of BRC, there is no direct connection to BRC-20. It is worth noting that an excessive pursuit of Programmability may actually disrupt BTC's valuation model. The limitations of BTC have, to some extent, contributed to its value.

EIP-7999 - Ethereum Multidimensional Fee Market Proposal

The EIP-7999 proposed by Vitalik aims to address the issue of Ethereum transaction fee fragmentation. This proposal introduces a unified multidimensional fee market, allowing users to set a single max_fee parameter, and the system will automatically allocate fees dynamically among different resources.

This direction aligns with Ethereum's L2 strategy, but the implementation complexity is high and requires a more robust pace of advancement. This proposal involves changes in multiple aspects such as block headers and encoding, requiring full-chain adaptation. Although it is difficult to implement in the short term, Vitalik's thoughts on the fee market are still worth exploring in depth.
