I have read in the documentation that the miners set the gas cost
. Does this means that gas cost varies from miner to miner? If not, how it is determined?
Moreover, when a contract is referred in geth we write:
var token = tokenContract.new( supply, { from:web3.eth.accounts[0], data:tokenCompiled.token.code,
gas: 1000000
}..........
What gas
is this? Is it the gas cost set by the client? Or the max gas to be used for the transaction?
