Solana Formally merged SIMD-0567 proposal, intending to use a version with high compute-unit efficiency to p-ATA replace the existing ATA program

According to BlockBeats,November 2, the official GitHub page shows that Solana Foundation has merged the SIMD-0567 proposal into the main branch. The proposal aims to use an optimized version developed based on Pinocchio p-ATA to replace the existing Associated Token Account (ATA) program, reducing compute unit (CU) consumption and improving execution efficiency.

According to the proposal,p-ATA uses a no-standard-library design, avoids heap memory allocation, parses instruction and account data through zero-copy methods, and minimizes dependencies. Previous benchmark tests by the developer showed that, compared with the legacy program,p-ATA can reduce transaction execution time by approximately 35%; when the Rent Sysvar account is provided,CU consumption is further reduced, but actual execution time increases slightly, with transaction-level time regression of approximately 1%. The proposal previously underwent multiple rounds of technical review and was formally merged 17 hours ago after completing formal verification of the new program, updating the program binary hash, and finalizing the migration process.

It should be noted that merging the proposal does not mean that the program replacement has already been completed on mainnet; deploying the new program in accordance with the established migration process is still required.

Key points

Solana The Foundation has merged the SIMD-0567 proposal into the main branch.
The proposal plans to use a version developed based on Pinocchio p-ATA to replace the existing Associated Token Account (ATA) program.
p-ATA It uses a no-standard-library design, avoids heap memory allocation, and parses instruction and account data through zero-copy methods.
Previous benchmark tests by the developer showed that p-ATA can reduce transaction execution time by approximately compared with the legacy program. 35%。
When the Rent Sysvar account is provided,CU consumption is further reduced, but actual execution time increases slightly, with transaction-level time regression of approximately 1%。
Merging the proposal does not mean that the program replacement has already been completed on mainnet; deploying the new program in accordance with the established migration process is still required.

AI-assisted interpretation

The following is analysis, separate from reported facts. Verify important claims independently.

This proposal has been merged at the code level, with the goal of enabling Solana to consume fewer compute units and improve execution efficiency when processing Associated Token Accounts. Merged code does not mean that the new program has already been deployed on mainnet.

Why it matters to readers

If deployment is completed later and the test results are achieved, transactions using Associated Token Accounts may have lower compute-unit consumption and higher efficiency.

For ordinary users, this is currently primarily protocol code progress and does not yet confirm that the mainnet transaction experience has changed.

Risks and unknowns

The evidence does not confirm that mainnet deployment has been completed.
Compute-unit consumption, execution time, and compatibility after actual deployment remain to be observed.
The evidence does not provide a direct official GitHub link, and the relevant information in the report should still be further verified.
