Solana Tech Roundup

Solana Devnet has started to get many features activated. Make sure you give each feature thorough testing with your application to check for any behavior changes. Changes such as the compute limit cap and rent exempt requirements can cause different behavior.

Proposal Highlight

Leader QoS

Proposal

The Leader QoS proposal outlines how transactions can be prioritized to be forwarded or included in a block. It outlines prioritization as:

1. Higher fee per CU
2. When fee per CU is the same, transactions from higher staked validators have a higher chance of getting included in a block

This proposal is still being discussion. Join the discussion!.
