#REI DAO #7 Proposal #BLS Signature Aggregation

REI Network, the new EVM-compatible public chain, plans to introduce BLS signature aggregation in the new version to improve blockchain performance, reduce network latency, improve security, and reduce operating costs. The community will vote on whether to allow the adoption of BLS signature in the upcoming upgrade.

Compared with the original ECDSA-SECP256K1 signature, the BLS signature will significantly reduce the storage space occupied by the block signature. The goal of this upgrade is to improve the efficiency of block broadcasting, reduce the size of blocks, and increase the security of the private key of the validator account.

The specific goals of the upgraded REI Network using BLS signature aggregation for the consensus level of blocks are:

1. Improve blockchain performance: BLS signature aggregation can aggregate multiple signatures into a smaller signature, reducing storage and transmission requirements, thereby improving blockchain performance;

2. Reduce network delay: Due to the small size of the aggregated signature, it can reduce the time required for network transmission, thereby reducing network delay;

3. Improve security: BLS signature has strong security, making it difficult for attackers to forge signatures or tamper with data;

4. Reduce costs: By reducing storage and transmission requirements, BLS signature aggregation can reduce system operating costs;

The community votes for the upcoming upgrade of REI Network to allow BLS signature aggregation, that is, multiple signatures are aggregated into a single signature, including contract registration, upgrade process, and technical specifications.
