According to BlockBeats, Solana's staking protocol Jito has introduced the IBRL Explorer, a new block explorer designed to provide insights into the internal structure of Solana blocks. This tool aims to address prevalent issues such as 'delayed packaging,' where transactions are concentrated at the end of slots, and 'slot time games,' which involve extending slot durations beyond their default values. The IBRL Explorer features an 'IBRL Score' that evaluates validator performance based on slot time, vote packaging, and non-vote packaging metrics.
