Free-tier Alchemy, Infura and QuickNode endpoints measured against six keyless ones and against a co-located node: request latency, burst ceilings, and which feed learns about a new block first.
A measured breakdown of Ethereum JSON-RPC latency: nine public endpoints at p50 and p99, the network floor separated from provider overhead, and the microsecond cost of local transports.
What a MEV searcher does, the infrastructure stack behind one, the latency budget, and whether you need to run your own Ethereum node to compete.
ePBS (EIP-7732) moves Ethereum's block-building auction into the protocol and retires the trusted relay. What ePBS is, how it works, when it ships with Glamsterdam, and what changes for searchers and builders.
MEV is won and lost on latency. Where the milliseconds go between the mempool and your transaction, and why co-located node access closes the gap.
