DNS
How Bitcoin Mining Works?
Block * header * transactions
Block Header * version * hashPrevBlock * hashMerkelRoot * time
* bits (difficulty) * nonce
Blockchain
Mining
Proof of Work ”A proof of work is a piece
of data which was difficult (costly, time-consuming) to produce so as to satisfy certain requirements”
"Hello, world!0" => 1312af178c253f84... "Hello, world!1" => e9afc424b79e4f6a... "Hello, world!2"
=> ae37343a357a8297... . . . "Hello, world!4248" => 6e110d98b388e... "Hello, world!4249" => c004190b822f1... "Hello, world!4250" => 0000c3af42fc3...
Auxiliary POW ”This is the way that merged mining can
exist; it is the relationship between two blockchains for one to trust the other’s work as their own and accept AuxPOW blocks.”
Bitcoin Coinbase * block height * flags * merged mining
prefix * namecoin prevhash * ...
Principle of Aux POW
None
Namecoin Block * header * auxpow (btc coinbase tx, btc
branch, btc header) * transactions
