BNB Chain is moving ahead with its Pascal hard fork. The testnet upgrade will happen on February 25, 2025, and the mainnet will follow in mid-March. This upgrade aligns BNB Chain with Ethereum’s Pectra update. It includes the Ethereum Execution Layer EIPs and other improvements.
Developers can discuss these changes on the BNB Chain Developer Forum. The forum allows open discussions about research, projects, and upgrades. Topics include BEPs, BNB Smart Chain, opBNB, Greenfield, SDKs, and applications.
BNB chain implements EIP-7702 for smarter transactions
EIP-7702 is a key part of the Pascal hard fork. This upgrade improves smart contract wallets and account abstraction. Users can manage accounts through smart contracts instead of private keys, making transactions more flexible and secure.
For most users, this update changes nothing. Tokens and dApps will work as usual. Wallet providers will update their systems. Only node operators need to upgrade their software. Some gas-sensitive dApps might require adjustments, but this is rare.
Developers need to pay attention to a block header change. A new field called RequestsHash is being added. It follows BEP-466 and aligns with Ethereum’s EIP-7685. If developers do not update their encoding logic, errors will occur. This field affects the block header root hash.
BNB Chain will not increase blob throughput like Ethereum. Blob targets stay at three, and the maximum remains at six. The upgrade enhances security, efficiency, and cross-chain interactions. Most smart contracts remain compatible.
Developers should use the testnet to explore contract account features. These include multi-signature wallets, account recovery, spending limits, batch transactions, and session keys. Old assumptions about private key control no longer apply.
BNB chain testnet chapel prepares for Pascal deployment
The testnet, called Chapel, is where developers can test updates. The BNB Chain roadmap lists the full details of upcoming changes. Developers working on projects like TOKI, which involve ledger consensus verification, should check compatibility. The new block header format affects verification mechanisms.
Past BSC hard forks like RamanujanBlock and MirrorSync focused on system contract updates. Pascal continues this evolution. The upgrade ensures that BNB Chain stays aligned with Ethereum while optimizing for its ecosystem.
The Pascal hard fork is a major step forward. It improves security, efficiency, and functionality. Developers should prepare, while regular users can sit back and enjoy a smoother experience. The future of BNB Chain looks promising.
