The free license for software modification on the condition that the same license remains on the product.

A General Public License (GPL) is the license attached to software which allows viewing, use, and even modification of the software provided that the same license remains on the software. Referred to as copyleft, this license category does not forbid copying of the specifications of computer programs. Instead, it encourages widespread use of the software and even possible alterations of their properties. However, when users modify programs with GPL, they have to distribute them under the same license, thereby giving the original developers due credit for their work.

GPL is originally derived from the GNU Project. Thus, it is one of the foundations for the development of open-source software.

Block 0 or 1, used to describe the first block created and verified on a blockchain network.

A genesis block is the block that was first created on any blockchain network. Being the very first block, it has no reference to previous transactions or blocks on the blockchain. Thus, it is traditionally referred to as Block 1, although new blockchain networks have modified the title to Block 0. Whichever the case, this block serves as the fundamental model for every other block on the network.

A genesis block is different from every other block. For one, it does not refer to any previous block since it is the first ‘page’ on the digital ledger. Secondly, the reward attached to it is more than the reward attached to the others.

The highest amount users on the Ethereum network are willing to pay for transactions.

The gas limit is the highest amount per transaction that a user is willing to pay for using the Ethereum network. It is a kind of guarantee mechanism for the speed of a transaction since it means that a user can ‘inspire’ miners to verify transactions quicker by setting a higher gas limit. Similarly, when a user sets overly low gas limits, the transactions usually take longer to verify since miners may not immediately pay the transaction any mind.

Thus, in the same way that gas is determined by miners who confirm transactions and oversee Ethereum blocks, it is also the prerogative of miners to agree to or ignore the fees imputed by users. The gas limit acts as the indicator for how committed a miner can be to a transaction.
