Transcript

  1. Merged Mining Ondrej Sika <[email protected]> Slush Pool (slushpool.com) 17. 3.

    2016, Bitcoin meetup Plzen, Czech Republic

  2. Bitcoin

  3. Namecoin * first altcoin * fork of bitcoin * distributed

    DNS

  4. How Bitcoin Mining Works?

  5. Block * header * transactions

  6. Block Header * version * hashPrevBlock * hashMerkelRoot * time

    * bits (difficulty) * nonce

  7. Blockchain

  8. Mining

  9. 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”

  10. "Hello, world!0" => 1312af178c253f84... "Hello, world!1" => e9afc424b79e4f6a... "Hello, world!2"

    => ae37343a357a8297... . . . "Hello, world!4248" => 6e110d98b388e... "Hello, world!4249" => c004190b822f1... "Hello, world!4250" => 0000c3af42fc3...

  11. 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.”

  12. Bitcoin Coinbase * block height * flags * merged mining

    prefix * namecoin prevhash * ...

  13. Principle of Aux POW

  14. None

  15. Namecoin Block * header * auxpow (btc coinbase tx, btc

    branch, btc header) * transactions
