Why GraphTally reads like x402, a year early: sub-cent, high-frequency, trust-minimized. Instead of transferring tokens per query, gateways attach a signed Receipt to each request, an IOU processed offchain in microseconds with no gas fees. Indexers aggregate those Receipts into a single Receipt Aggregate Voucher (RAV) and settle a whole batch onchain in one transaction. x402 brings this shape to the wider internet; GraphTally has run it at network scale. Protocol innovation at its finest.(The Graph)
