Flowra launched its Open Orderflow Auction on 21 August 2026, a block-building framework that lets registered searchers bid openly for Solana transaction inclusion instead of routing through closed orderflow channels. The Seoul-based company also introduced Programmable Block Policy, which lets validators define their own transaction inclusion rules at the block-building layer without changes to the Solana protocol, with sanctions and risk screening supplied through a collaboration with Honeypot. In early testing on a single validator, a Flowra-enabled setup raised compute units per block by 20.6%, moving that node from 84% to 101% of the network average, with 100% block production and 99.999% block engine uptime.

HTLCs are the trick that lets Lightning move money across nodes that don't trust each other. A payment is locked to a secret's hash, and each hop can only claim its funds by revealing that secret - which in turn lets the previous hop claim theirs. A time-lock guarantees that if the payment stalls, everyone gets refunded instead of losing money. It's how a payment hops through strangers safely, with no one able to steal in the middle.
