The public key must be the correct one to claim the transaction output this claims, that is, the one the coins were sent to. bitcoin scripts use opcodes. they're documented in the wiki. that is the bitcoin address that can claim this output (in raw binary form), assuming the transaction is a transfer to a bitcoin address.. Bitcoin transactions are sent from and to electronic bitcoin wallets, and are digitally signed for security. code, transaction fees and 'gas' what is bitcoin cash? same blockchain, different. This means to get the fastest fee i have to multiply the size of my transaction by 70. normal bitcoin transactions are about 200byte, so my transaction fee should be 70*200=14000. wow, that's a lot of bitcoins isn't it? not really these are satoshis. 1 satoshi = 0.00000001 bitcoin. so my 14000satoshi is 0.00014btc. that's 0.1usd at the time of.
The blockchain is the complete "database" of every transaction that has ever occurred on bitcoin. every full node (which is the downloaded bitcoin software) has an identical copy of this database. new transactions are added to this database through "blocks", which are created by miners using [mining].. De facto, bitcoin script is defined by the code run by the network to check the validity of blocks. the stacks hold byte vectors. when used as numbers, byte vectors are interpreted as little-endian variable-length integers with the most significant bit determining the sign of the integer.. Use the signrawtransaction rpc to sign the transaction created by createrawtransaction and save the returned “hex” raw format signed transaction to a shell variable. even though the transaction is now complete, the bitcoin core node we’re connected to doesn’t know anything about the transaction, nor does any other part of the network..
