nonce – How will mining work after 2140?
The nonce header of a block has 32 bits. The overwhelming majority of the time, not one of the 2^32 nonces will end in a block hash under the goal. So to proceed mining, miners normally change the extraNonce within the coinbase transaction. However what’s going to occur as soon as all of the bitcoins have been mined and there’s no coinbase transaction anymore? I do know it will solely occur in 2140, however have we considered a method to change the nonce vary when will probably be the case?
Thanks to your assist.
