(1) The transmission modes are the same.
Bitcoin cash and bitcoin are completely dispersed. The central bank does not issue it, nor does it need third-party operation, but electronic cash transmitted through the Internet.
The predecessor of bitcoin cash was bitcoin. Before the fork, the data stored in the blockchain and the running software were compatible with all bitcoin nodes, but after the fork, it had little connection with bitcoin and became a brand-new currency.
(2) The block capacity for recording transaction information is different.
The block size of Bitcoin is 1MB, but the block size limit of 1M is cancelled by deleting SegWit from Bitcoin cash. The maximum block size can be 8M, and the expansion route on the chain is adhered to. It is a blockchain asset generated by BitcoinABC scheme, which has greater stability and security. More transactions can be supported in a specific time. The size of the first BCH block dug by Bitcoin cash has exceeded 1MB.
(3) The algorithm difficulty between them is different.
There are at most 2 1 10,000 bitcoins. Bitcoin cash adopts dynamic difficulty adjustment mode, and the production difficulty will be adjusted with the computing power in the entire bitcoin cash network.
