this is a static protocol fact, not derived from chain state in the pinned block window, bitcoin core source and documentation (src/key.cpp / bip-32/bip-340 references) specify ecdsa/schnorr signatures over the secp256k1 curve, as defined in sec 2: recommended elliptic curve domain parameters, bitcoin core source and documentation specify that bitcoin's ecdsa signatures use the secp256k1 elliptic curve (sec 2 standard curve secp256k1, as referenced in bip-32/bip-62 and bitcoin core's libsecp256k1 library)., bitcoin core, bitcoin-core/secp256k1 readme: https://github.com/bitcoin-core/secp256k1 (describes libsecp256k1 as a signatures library for the secp256k1 curve and says its primary focus is use in bitcoin)., bitcoin developer documentation, transactions: https://developer.bitcoin.org/devguide/transactions.html, bitcoin uses the secp256k1 elliptic curve for ecdsa signatures (and schnorr signatures since taproot), as specified in sec 2: recommended elliptic curve domain parameters and referenced in the bitcoin source code (src/secp256k1 library) and bip 340., bitcoin uses the secp256k1 elliptic curve for ecdsa/schnorr signatures, as specified in sec 2: recommended elliptic curve domain parameters (certicom research) and reflected in the bitcoin core source (src/secp256k1 library) and bitcoin improvement proposals (e.g. bip-340 schnorr signatures)., bitcoin wiki, elliptic curve digital signature algorithm (https://en.bitcoin.it/wiki/ecdsa), and opensats secp256k1 topic page (https://opensats.org/topics/secp256k1): bitcoin signatures use the secp256k1 curve, bitcoin.org, developer.bitcoin.org, en.bitcoin.it, sec 2 (standards for efficient cryptography, v2, section 2.4.1) defines secp256k1; bitcoin core uses it via its src/secp256k1 library (bip 62 / bip 66 reference the curve by this name), sec 2: recommended elliptic curve domain parameters (certicom research, secp256k1 section); bitcoin core src/secp256k1 library, which implements that curve for bitcoin signatures, sec 2: recommended elliptic curve domain parameters (certicom, 2000) and bitcoin core source (src/key.cpp) specify secp256k1 as the curve used for ecdsa signatures in bitcoin, sec 2: recommended elliptic curve domain parameters (certicom, v2.0), section 2.4.1 secp256k1, and the bitcoin wiki/bitcoin core source (src/secp256k1), which both name the curve secp256k1 used for bitcoin signatures (ecdsa), sec 2: recommended elliptic curve domain parameters (secg.org), section 2.4.1 secp256k1; bitcoin wiki secp256k1 page, sec 2: recommended elliptic curve domain parameters (secp256k1 defined in section 2.4.1); bitcoin core source tree, src/secp256k1 library, which implements secp256k1, www.secg.org
