Discuss subtle header difference between Proof of Transaction vs BTC Proof of Work

BTC requires miner to constantly adjust “nonce” field in the header to compete the block hash to include enough zeros. The processing sequence is packaging transaction first then mining. The hashing result depends on the entire block content. BTC header can not seperate from block content in mining.

POT does not require transaction content to participate mining. The processing sequence is signature generation once only in header then packaging transactions. The hashing result only relates to timestamp and public keys content.

The result is POT need much less computing resource and POW requires “constant adjust and hashing” which is described as work in a high computing power environment. This subtle difference makes POW not possible to operate in a mobile phone and wild global mobile network.
