The Solana (SOL) community is actively discussing increasing the network’s Compute Unit (CU) capacity, a crucial metric that regulates transaction complexity and saves network resources.
Compute Units function similarly to Ethereum’s gas fees, ensuring transaction efficiency and protecting the blockchain from excessive computing demands.
Currently, Solana’s block limit is set at 48 million CUs. However, recent proposals, including SIMD-0207 and SIMD-0256, suggest increasing this limit to improve network performance. SIMD-0207 suggests a modest increase to 50 million CUs, while SIMD-0256 advocates a more significant increase to 60 million CUs.
Solana developers state that the current block limits serve to maintain network stability by ensuring that the majority of participants can keep up with the transaction process. However, they note that current mainnet traffic is not significantly constrained by block execution times, leaving room for capacity expansion.
“The primary purpose of block limits is to ensure that network participants can keep up with block transactions,” Solana developers said. “This proposal targets a significant increase to 60 million CUs to provide additional capacity without straining the network.”
Alternative strategies also featured in the discussion on CU expansion:
- Not changing block limits: This approach maintains network stability but leaves potential capacity unused.
- A larger increase to 96 million CUs: This is currently considered too aggressive as it could lead to unforeseen challenges, particularly impacting the infrastructure supporting the turbine protocol and users.
Rather than making a radical change, developers prefer to make a gradual increase in CU limits to align with ongoing improvements in network performance.
