Bitcoin does not use RSA in its core cryptographic design. Its security relies entirely on Elliptic Curve Cryptography (ECC) and hash functions (SHA-256 and RIPEMD-160). Here’s why RSA is absent and what Bitcoin actually uses:

Private/Public Key Pairs:

Bitcoin uses the Elliptic Curve Digital Signature Algorithm (ECDSA) with the secp256k1 curve. Private keys are 256-bit numbers, and public keys are derived via ECC. This differs from RSA, which relies on large prime factorization.

Address Generation:

Public keys are hashed (SHA-256 + RIPEMD-160) to create Bitcoin addresses. This process does not involve RSA.

Transaction Signing:

Transactions are signed with ECDSA, not RSA. Nodes verify signatures using the sender’s public key without requiring RSA-based encryption.

That's why I always indicate the source of my publications. Thanks nostr:npub158x7tu26f0uvm7mkzavp95xj99pav7pqrh7f64ldm62f920mcklq9h76wm
