It is encoded by filling the high-order byte of the uint64 type with  1s, then converting it to a byte sequence. This process grants Nonce uniqueness during the encoding and decoding process. In practical applications, Nonce is usually encoded together with other transaction information, such as transaction hash and timestamp, to form a complete transaction data structure. This data structure is then sent to the blockchain network for verification and propagation."}]}],"pr":"513145b3a76908113843febd431109bde17d2ce9c08a65ccac91a8c8bb0b6ee5"}
