A销毁指定 type 即可解锁Unlock by burning a given type
Inputs 输入Inputs
inputCell{ lock: { codeHash: TYPE_BURN, args: type_hash 32B } }
被销毁的 cellburnt cellCell{ type: hash = type_hash }
➜
Outputs 输出Outputs
outputs：无该 typeoutputs: none with that type任意（不能含 type_hash）any (none with type_hash)
args 字节布局args byte layout
type_hash32B
- type_hash 32B 需销毁的 type 脚本哈希type script hash to burn 在输入中、不在输出中in inputs, not in outputs (6)
限制Constraints
- args ≥ 32 字节≥ 32 bytes (4)
- burn：: 有输入的 type hash = args[0..32]，且没有输出带该 typean input has type hash = args[0..32] and no output has it (6)
