Class BSV::Primitives::KeyShares ¶

Inherits: Object

A set of Shamir's Secret Sharing shares derived from a private key.

Holds the evaluation points (shares), a reconstruction threshold, and an integrity string for verifying that recombined shares produce the correct key. Supports serialisation to and from a human-readable backup format.

Backup format per share: "Base58(x).Base58(y).threshold.integrity"

This format is compatible with the Go and TypeScript reference SDKs.

@example Round-trip through backup format

shares  = key.to_key_shares(2, 5)
backup  = shares.to_backup_format
rebuilt = KeyShares.from_backup_format(backup[0..1])
key     = PrivateKey.from_key_shares(rebuilt)

Attributes¶

`integrity` [R] ¶

@return [String] first 8 hex characters of the Hash160 of the compressed public key

`points` [R] ¶

@return [Array] the share points

`threshold` [R] ¶

@return [Integer] the minimum number of shares required to reconstruct the key

Public Class Methods¶

`from_backup_format(shares)` ¶

Deserialise shares from backup format strings.

Each string must have the form "Base58(x).Base58(y).threshold.integrity". All shares must agree on threshold and integrity. - @param shares [Array] backup-format share strings - @raise [ArgumentError] if any share is malformed or shares are inconsistent - @return [KeyShares]

Public Instance Methods¶

`initialize(points, threshold, integrity)` ¶

@param points [Array] share points
@param threshold [Integer] reconstruction threshold
@param integrity [String] integrity check string
@return [KeyShares] a new instance of KeyShares

`to_backup_format()` ¶

Serialise shares to backup format strings. - @return [Array] one backup string per share point
