Stellar
A public blockchain Truestamp uses two ways: Stellar ledger closes are captured as entropy observations, and epoch roots are committed as a transaction MEMO_HASH, appearing in a proof bundle as a commitments entry with chain stellar and a network of testnet or public.
Overview
Stellar is a public blockchain that Truestamp uses in two independent roles. As an
entropy source, each closed Stellar ledger’s consensus
hash is captured as an entropy observation that joins a Truestamp block’s Merkle tree
(see external entropy sources). As a commitment chain,
epoch roots are recorded as a Stellar transaction’s memo hash
(MEMO_HASH) as part of Block Commitment; a Stellar
commitment typically appears within minutes, faster than
Bitcoin, so it is usually the first public witness a block gets
(see the epoch and Block Commitment). In a
proof bundle, a Stellar commitment is a
commitments entry with a chain of "stellar" and a network of testnet or
public, carrying the ledger number, the transaction hash, the epoch root written as the
memo, and the epoch proof.
