Base has tested the web-based deployment of Beryl upgrades in Sepolia, with the main line scheduled for 25 June. The focus of the update included the introduction of the original token standard B20 and the shortening of the routine waiting period from Base to the Ether.
B20 can issue assets directly on the protocol level.
Base indicates that B20 is a set of protocol layers of original tokens that issuers can create stable coins and other assets directly within the Base node software and no longer rely exclusively on traditional smart contracting.
According to the official note, B20 is compatible with the full ERC-20 and supports the ERC-2612 permit function. Users can sign to authorize expenditure without having to initiate a separate approval transaction. Base states that existing wallets, exchanges and indexing tools supporting the ERC-20 are normally not subject to modification when accessing B20 assets.
Unlike common ERC-20 tokens, B20 runs a pre-compilation contract in Base Node software. Base indicates that this token logic is written using Rust and is executed directly on the protocol level, rather than running through EVM bytes.
More controls for the issuer of stable currency
The release also included a distribution toolkit to support role-based competency management, as well as additional, destroyed, optional supply caps, transfer restrictions, freezing and seizure functions. Base states that these designs are primarily for regulated issuers.
The issuer selects between two models: a generic asset model and a dedicated model for a stable currency. The latter uses 6 decimal precisions and allows custom currency codes.
Base further stated that B20 was based on codes that were audited by itself and the security company Spearbit. The follow-up update also plans to support the issuer in the use of B20 tokens to pay transaction fees, rather than using ETH only.
Reduction of the waiting period from 7 to 5 days
Beryl also continued the Azul upgrade at the main line in May. Azul introduced the Multiproofs mechanism, which combines a credible implementation environment certificate with a zero knowledge certificate to validate cash withdrawals and enhance safety.
Base states that, when the results of the two sets of certificates are consistent, Multiproofs can provide a quick cash withdrawal path that is approximately one day complete. However, because of the high cost of generating zero knowledge, the path is still limited in scope.
As a result, Beryl has largely optimized the conventional cash withdrawal routes that are still being used by most cross-chain service providers. Base indicates that the seven-day waiting period in the past seven days came from the early fault-proof framework, which set aside challenging time for the presentation of disputes. As Multiproofs narrowed down the effect of the delay, the waiting period was moved down to five days.
Base also mentioned that Beryl entered the Sepolia Test Network about four weeks after the Azul main line. The company attributed the faster pace of upgrading to its decision in February this year to move away from Optimism OP Stack to a single technology warehouse.
September plan went online, Cobalt.
The next planned upgrade is called Cobalt and the target date is September. Base is expected to introduce original accounts in abstract, protocol-level smart accounts, Gas sponsorship, transaction batch processing, more B20 functionality, and a unified node binary program to integrate consensus and implement client.
