Why choose to "access the mature proof market" instead of building your own cluster?

Many teams working on ZK/verifiable computation instinctively think of building their own prover clusters, but by the end of 2025, a better solution will actually be "buying proofs as a product."

First, the production capacity is ready. Succinct has officially confirmed Cysic as a multi-node prover entering the Prover Network, directly using GPU clusters to undertake production-level orders; you just throw the tasks in, and it's "take the job as it comes, settle by volume," without needing to spend money upfront on buying cards or setting up management and scheduling.

Second, costs can be continuously reduced. The C1 developed by Cysic aims to lower $/proof and W/proof further, in addition to the existing GPU optimization—buying results is more like a "utility" than renting machines.

Third, settlement and automation are smoother. They have expanded Google's A2A to Crypto A2A, adding payment_required to the standards, supporting prepayment and settlement, and on-chain confirmation before execution. Automated tasks can follow the "Order → Payment → Execution → Receipt" closed loop, eliminating the need for your own payment and reconciliation glue layer.

If you are making a technology selection, the decision-making framework can be laid out like this:
- Use SPN throughput/failure rate to verify "whether it can really withstand production load". Succinct
- Compare self-built vs purchased external proofs using $/proof and W/proof (including hardware depreciation, electricity costs, and labor).
- Check A2A paid conversion to confirm whether your task flow can automatically settle end-to-end.
