"Gas" is the name for a special unit used in Ethereum. It measures how much "work" an action or set of actions takes to perform: for example, to calculate one Keccak256 cryptographic hash it will take 30 gas each time a hash is calculated, plus a cost of 6 more gas for every 256 bits of data being hashed. Every operation that can be performed by a ...

Short: Gas is the execution fee for every operation made on ethereum. Its price is expressed in ether and it's decided by the miners, which can refuse to process transaction with less than a certain gas price. To get gas you simply need to add ether to your account. Long: Ethereum implements on the blockchain an execution environment called the Ethereum ...

The following response is taken from Ethereum, Gas, Fuel & Fees What is Gas? Gas is the metering unit for use of the Ethereum "World Computer". As an analogy, electricity is metered by kilowatt hours. Using more computation and storage in Ethereum means that more gas is used. One fundamental reason for metering is that it provides an incentive for ...

Additional useful content on gas in Ethreum from: http://ethdocs.org/en/latest/ether.html#gas-and-ether Gas and ether Gas is supposed to be the constant cost of network resources/utilisation. You want the real cost of sending a transaction to always be the same, so you can’t really expect Gas to be issued, currencies in general are volatile. So instead, ...

Gas is basically the internal pricing for running a transaction or a contract. The gas price per transaction or contract is set up to deal with the Turing Complete nature of Ethereum and its EVM (Ethereum Virtual Machine Code) So, the more complex the transaction or the operation, the more gas it would cost.

In the current vision of Casper Proof of Stake protocol, the validators (who are staking), when eligible, need to bet on the finality of blocks. More technically speaking, each bet has to specify for each block height: which block will most likely win, and with what probability. Validators will be constantly updating their bets, thereby converging to ...

Can mining pool A now launch a 51% attack? If so, when will the difficulty be adjusted to account for the massively reduced mining power? The difficulty will be adjusted at the next block, unlike Bitcoin, which adjusts every 2016 blocks. (Or at least it used to. Unsure if that's still the case.) However, they would have to find the PoW of the current block ...
