How BidBlock changes block production on BSC:

🔸 Builders submit execution results with their blocks.
🔸 Validators re-execute after broadcast.
🔸 SendBid remains available as a fallback.

Payment Lane is one of the changes coming to BSC testnet with Jenner.

It introduces reserved gas capacity for eligible payments while keeping existing fees and transaction ordering unchanged.

Here’s the setup:
🔸 5% of block gas reserved by default.
🔸 General transactions cannot use unused reserved gas.
🔸 Eligible payments can compete for the rest of the block.
🔸 Token contracts require separate governance listing.

The testnet rollout gives developers and block builders a place to check eligibility and block accounting before production.

Building on BSC with millisecond deadlines? Jenner adds a read-only call to 0x70 that returns block time in milliseconds.

Keep units consistent across contracts, signatures, and backends. block.timestamp still uses seconds.

Governance mechanisms for CAS20 and Payment Lane have been implemented and verified.

The Jenner hardfork now brings three key updates to BSC testnet:

🔸 CAS20 functionality: Lays the groundwork for a new Compliant Asset Standard, with tools to manage token transfers, supply, and pauses.
🔸 Payment Lane: Reserves 5% of block capacity by default for eligible payments.
🔸 Millisecond timestamps: Gives smart contracts more precise timing for things like quote expiry and auction cutoffs.
