MPC1 交易更新说明
以下示例数据均来自测试网。
PoS 块
一个合法的 PoS 块的 block_version 为 2，块头中包含 blocksig 字段（该字段是矿工对整个块的签名），且至少包含一个 coinbase 交易与 coinstake 交易。
coinbase交易：与PoW块的coinbase结构完全一样，其outputs包含挖矿奖励。coinstake交易：其inputs为可以作为PoS权益证明的UTXO，其outputs第一个为空output，该空output以标识该交易为coinstake交易。
示例：
测试网块高 1019574 的 PoS 块构成如下所示：{

该 PoS 块包含两个交易：
- 第一个交易为
coinbase，其哈希为0ca5c0e285c180256b44eae94d570fc67366c52ed4fa62a4dd9e9c07e3eddc99； - 第二个交易为
coinstake，其哈希为c246e71b06e75c7d56b7120fda9c8344c45b0aaf4922e8bea8c7ff50b7e79d8e；
PoS 创世块
创世块也是一个 PoS 块，因此也包含 coinbase 和 coinstake 交易。此外它还包含第三个交易： PoS 创世交易，该交易包含发送到元界基金会地址的创世奖励以及 23 个 witness 一级证书。
示例：

该 PoS 创世块包含三个交易：
- 第一个交易为
coinbase，其哈希为e7a25724eccc05fb5f36d14c6e851037dd9e3c9f5002853c2e623e7a64b790f8； - 第二个交易为
coinstake，其哈希为21ab6dca066b6a7cdbaa71f4564f6979b9484b86c387885d91126a03f54949fc； - 第三个交易为
PoS创世交易，其哈希为9a71d084b472468421012b1c4a25ef3e2e42d2712069d2a447a7befaab92bcad；
Relative lock-time (RLT) 相对时间锁交易
Metaverse 实现了 BIP112 中定义的相对时间锁机制。带有相对时间锁交易的脚本中包含操作码 CHECKSEQUENCEVERIFY (使用操作码值为NOP4 (=179) 而非NOP3 (=178)，由于 NOP3 已经被元界另一个扩展功能(CHECKATTENUATIONVERIFY)占用了。请注意此处与比特币的不同。)。
示例交易如下：
交易2912621cb70244d878ed0594d1bf841191d5323347cad76b3126085220692702 通过相对时间锁锁仓 1000 ETP，锁仓块高为 10000000，其值对应脚本中第一个操作数的十六进制 969800 部分。
其交易构成如下：{
