Solana SIMD-0266 Proposal: p-token replaces SPL Token, CU usage will be reduced by 98% after the upgrade

According to Foresight News , Anza, a research and development company focused on Solana, tweeted about the SIMD-0266 proposal. Written by febo, the proposal recommends replacing the current SPL Token program with a compute-optimized version, p-token. After the upgrade, compute unit (CU) utilization will be reduced by up to 98%. Currently, token program instructions account for approximately 10% of block CUs. P-token will free up nearly 12% of block space, increasing Solana's effective throughput. P-token is a complete reimplementation of the SPL Token, supporting heap-free allocation, zero-copy data access, and full backward compatibility, allowing for a direct replacement without modifying client code. New instructions such as Batch and UnwrapLamports reduce computational complexity in common DeFi patterns, support multi-token operations per CPI, and eliminate the need for temporary native accounts. This proposal will work in conjunction with other network optimizations, such as the 100M CU block size, to improve the overall performance and transaction throughput of the Solana network.
