Solana's SIMD-0370 Proposal Aims to Revolutionize Network Scaling

Say goodbye to fixed block limits on Solana. The SIMD-0370 proposal aims to scale the network based on validator hardware, but not everyone is convinced.

Solana's SIMD-0370 Proposal Aims to Revolutionize Network Scaling

Solana is set to revolutionize its network scaling with the SIMD-0370 proposal. This plan aims to remove the fixed block limit, allowing validators to process transactions based on their hardware capabilities. The proposal, developed by the Firedancer team at Jump Crypto, is part of a collaborative effort involving the Solana Foundation and the Solana Identity Group.

The SIMD-0370 proposal argues against artificial caps, advocating for automatic scaling based on validator capabilities. If implemented, this would shift Solana's scaling from centrally-planned capacity limits to market-driven growth. This comes as Solana prepares for its biggest upgrade yet, Alpenglow, scheduled for testnet deployment in December 2025.

Under SIMD-0370, block producers could pack more transactions into a block, with slower validators potentially skipping complex blocks. This has sparked concerns about centralization, with critics warning that larger validators could dominate the network. Currently, the fixed limit is 60 million compute units per block, with an earlier proposal suggesting raising it to 100 million.

The SIMD-0370 proposal is set to transform Solana's network scaling, moving away from fixed limits towards hardware-based processing. While it raises concerns about centralization, the proposal is part of Solana's broader effort to improve its block capacity and decentralized identity verification, as seen in the upcoming Alpenglow upgrade. With overwhelming validator support, Alpenglow is set to testnet deployment soon, potentially paving the way for SIMD-0370's implementation.
