Wu said that according to Jito's announcement, they have launched the IBRL Explorer tool, which for the first time publicly and transparently displays the construction details within Solana blocks. The tool shows that behaviors such as "tail packing" and "Slot Timing Games" are common in the Solana network, which may affect the efficiency of state propagation, increase latency, and weaken network stability. The IBRL Explorer generates an IBRL score for each validator through three scoring mechanisms: Slot Time, Vote Packing, and Non-Vote Packing, aiming to improve block construction quality and overall network performance.
