Solana Upgrade Proposal Aims to Scrap Fixed Compute Unit Limits
Jump Crypto’s Firedancer team has introduced a new proposal, SIMD-0370, designed to overhaul how Solana handles block capacity.
Instead of relying on the current fixed compute unit (CU) block limit, set at 60 million and scheduled to rise to 100 million, this proposal would let block producers determine how many transactions to pack into each block.
The suggested change would create a performance-driven cycle: faster validators would earn more by processing maximum transactions, while slower validators that fail to keep pace would lose rewards until they upgrade their systems.
Over time, this dynamic would naturally encourage the network to scale as validator power increases, rather than being held back by static limits.
By shifting away from fixed thresholds, Firedancer’s plan envisions Solana’s throughput growing in tandem with validator performance. That could significantly improve efficiency and make the network more resilient under heavy demand.

If adopted, the proposal would represent another step in Solana’s broader strategy of pushing technical upgrades to maintain its position as one of the highest-throughput blockchains in the industry.
