Standalone HTML tools for multiple blockchains, currently supporting Bitcoin, Ethereum and Dash: offline key derivation and recovery backups, read-only activity and discovery, PSBT inspection and multisig policies.
Sharded Secret Key Reconstruction (SSKR) is a protocol for splitting a secret into a set of shares across one or more groups, such that the secret can be reconstructed from any combination of shares totaling or exceeding a threshold number of shares within each group and across all groups. SSKR is a generalization of Shamir's Secret Sharing (SSS)
A pure TypeScript implementation of Shamir's Secret Sharing (SSS), a cryptographic technique in which a secret is divided into parts, called shares, in such a way that a threshold of several shares are needed to reconstruct the secret.
Dash Community wallet tools: standalone HTML for offline key derivation and recovery backups, read-only activity and discovery, PSBT inspection and multisig policies. Independent community project.
