Type Members

  1. case class AdditionTrieNode(preComputeTable: Vector[Vector[ECPublicKey]], depth: Int = 0, children: Vector[AdditionTrieNode] = Vector.empty, pointOpt: Option[SecpPoint] = None) extends Product with Serializable

    This trie is used for computing adaptor points for a single oracle corresponding to digit prefixes while memoizing partial sums.

    This trie is used for computing adaptor points for a single oracle corresponding to digit prefixes while memoizing partial sums.

    For example the point corresponding to 0110 and 01111010 both begin with the 011 sub-sum.

    This trie stores all already computed sub-sums and new points are computed by extending this Trie.

    Note that this method should not be used if you have access to LibSecp256k1CryptoRuntime because calling CryptoUtil.combinePubKeys will outperform memoization in that case.
