官方科普：Circuit 只读调用、无需 gas 且可复算TapeOut Explainer: Circuit Calls Are Read-Only, Gas-Free and Recomputable

A great read for newcomers, three things to add Any finished Circuit can be called by anyone, a read only query, no wallet, no cost Circuits other people built can be dragged into your design as parts Only trust contract addresses from the official site and official accounts, never from DMs If you

In TapeOut, a mining rig isn't a machine It's a taped out Circuit that solved a task in PoD The better the design, the higher its hashrate It stays On Chain and produces under the rules So it's called mining, but what's really being compared is who built the better Circuit

What a Circuit stores On Chain isn't a piece of code It's a record of which gate connects to which No hidden functions No permission to call anything else Nothing that can be changed To know what it does, you just read that record

Calling a Circuit is a read only call The request goes to a node, the node computes the circuit locally and returns the result No transaction is broadcast No On Chain state changes So no gas is paid

A Circuit only records how gates connect, it doesn't read outside data or write any state So it's fully deterministic The same input gives the same result on any node, at any time You don't need to trust who computed it, compute it again yourself and you'll know
