.@solana's failure rate fell alongside faster slots. Comparing the 400ms and 200ms periods, the share of landed non-vote transactions that failed dropped from 44.5% to 30.6%. Failures also consumed less of the total non-vote compute: 29.8% → 20.9%. Esentially this means a bigger share of compute going to transactions that actually succeed. Bullish

Axiom's $55.7M "Validator Bribe" Rip-Off on @solana. @AxiomExchange is deliberately extracting millions from its traders through misleading transaction fees. I stumbled upon this piece of data while exploring our database, here's our analysis 👇

Following the mempool article, the reported* stake share onboarded to Everstake's Blockspace dropped by 46% 🎉 In an onchain NASDAQ future, services such as the one offered by Everstake enable toxic MEV and insider trading. Thank you for your attention to this matter.
Orderflow article is out. Private TPU feeds, a rev-share vault, and the validators getting paid from it.

SIMD-0675 would reorder Solana's leader schedule so nearby leaders go one after another. Replayed on 10 recent epochs, this geo-aware schedule would cut the mean leader hop in half (3,657 → 1,808km). Asia and the US gain the most (20-27ms per handover); Europe ~9ms.
Solana block production with a geo-aware leader schedule (SIMD-0675) and a run length of 5. 👇
