    • Method Detail

      • genesisHash

        public void genesisHash​(String base64Encoded)
        (gh) hash to which this block belongs.

      • genesisHash

        public String genesisHash()

      • previousBlockHash

        public void previousBlockHash​(String base64Encoded)
        (prev) Previous block hash.

      • previousBlockHash

        public String previousBlockHash()

      • seed

        public void seed​(String base64Encoded)
        (seed) Sortition seed.

      • transactionsRoot

        public void transactionsRoot​(String base64Encoded)
        (txn) TransactionsRoot authenticates the set of transactions appearing in the block. More specifically, it's the root of a merkle tree whose leaves are the block's Txids, in lexicographic order. For the empty block, it's 0. Note that the TxnRoot does not authenticate the signatures on the transactions, only the transactions themselves. Two blocks with the same transactions but in a different order and with different signatures will have the same TxnRoot.

      • transactionsRoot

        public String transactionsRoot()

      • transactionsRootSha256

        public void transactionsRootSha256​(String base64Encoded)
        (txn256) TransactionsRootSHA256 is an auxiliary TransactionRoot, built using a vector commitment instead of a merkle tree, and SHA256 hash function instead of the default SHA512_256. This commitment can be used on environments where only the SHA256 function exists.

      • transactionsRootSha256

        public String transactionsRootSha256()
