    Hearing some feedback -- so let me emphasize some points here: 1) the goal is to make this dataset of transaction shred dissemination timing more transparent and accessible for validators, researchers, and the broader Solana ecosystem, so we make the parquet files downloadable

    Over the last 20 epochs, we tracked validator scheduling and block production behavior using shred data Now we’re making that data available on a revamped dashboard, along with a provisional scoring system

    How parallelizable is the EVM? Introducing par.tryghost.xyz Max parallelism is based on how dependent transactions are We looked at all blocks to find out. Now you can visualize the transaction dependency graph for any ethereum block, and it updates in real time

    Due to popular demand, we investigated where validators with the highest sandwich rate get their stake The top 3 sandwiching validators (by % of blocks with sandwiches) get virtually all of their stake from Marinade Stake is active stake as of epoch 779 Sandwich rate over 30d
    Relative source of stake of Solana validators

    1/7 Almost a month has passed since epoch 805. Sharing the latest sandwich <-> validator data for epoch 819 @MarinadeFinance removed the worst offenders from their stake pools, which has had a significant impact in reducing sandwich attacks on Solana

    Last day of Hackathon! Met this superstar @el33th4xor today talking about the subnets on Avalanche. Talk to me if you want to test out an easy way to spin up your own subnet and a blockchain on Avalanche with built-in block explorer.
