Blockchain

The Blockchain module implements several specific operations for processing blockchain network cryptography and BIP, EIP and SLIP specifications.

The ECDSA signature, for example, is specialized to avoid signature malleabilitywith the restriction of LOW-S.

Examples of operations available in the Blockchain module:

1. Extended Private Key (XPrv) generation in the BIP32 standard.
2. Child Key Derivation in the BIP32 and SLIP10 standards.
3. Address recovery.
4. ECDSA digital signatures, in SECG strict DER standards (BIP62/66 and BIP 146) and Schnorr in BIP340 standard;
5. Digital signatures EdDSA curve 25519.
6. Signature verification.
7. Import and export of keys via various formats (WIF, Hex, Sec1, Xpriv etc).
8. Recovery of the public key with different formats (BIP32 Xpub, Sec1 with and without compression, Schnorr BIP340 etc).
9. Split and Recover secrets with M from N scheme using SSS (Shamir's Secret Sharing).
10. Operations with the curve alt_bn128according to EIP-196.

Attention

The blockchain module does not handle or assemble the transaction details for each particular network; this must be left to the application. The function of the HSM is to protect the private key in a secure environment, generate and return a signature according to the parameters passed by the calling application.

Compatible networks

Below is the list of networks whose encryption is compatible with HSM:

Info

The algorithms listed are those currently implemented in the HSM that allow transactions to be signed on the network and do not necessarily cover all the options defined in the network specification. If you have any questions, feel free to contact Dinamo Networks support and ask them.
