Solana Considers Removing Block Limits

Solana Proposal to Remove Block Limits Aims for Higher Throughput

  • Solana developers propose removing the current block limit of 60 million compute units per block.
  • The proposal, filed as SIMD-0370, would allow block sizes to adjust dynamically based on validator hardware capabilities.
  • The Alpenglow upgrade will introduce a skip-vote feature, enabling smaller validators to abstain from oversized blocks.
  • Jump Crypto’s Firedancer team argues that the current incentive structure is broken and favors larger operators.
  • Critics warn that this change could centralize power among well-funded operators with high-end hardware.

The proposal to remove Solana’s block limits aims to increase throughput by allowing blocks to expand dynamically according to validator performance rather than fixed limits. This change is part of the upcoming Alpenglow upgrade, which also includes features like skip votes for smaller validators.

By tying Solana’s capacity directly to validator performance, the network could potentially handle more transactions but may risk increased centralization as larger operators benefit more from these changes. Source)
