ckBTC: a canister-issued bitcoin twin token on the IC, 1:1-backed by BTC

Good question! The term “NNS Canister” is not entirely precise, I think it’s used for both canisters that run on system subnets, and for canisters that are controlled by the NNS.

  • if a canister runs on a system subnet (as shown here), they do not cost cycles.
  • a canister that is controlled by the NNS but does not run on a system subnet, the canister pays cycles as usual

The canisters of ckTESTBTC run on the new fiduciary subnet (pzp6e), so this canister does pay cycles. Even more so than on other subnets, because it’s a larger subnet. We plan on running the real ckBTC on the same subnet.
