How To Add Gas To Ledger Nano S

What is Gas?

Gas is one of the fundamental concepts in the Ethereum blockchain network. It is a unit used to measure the computational effort required to execute transactions and run smart contracts on the network. In simple terms, gas is the fuel that powers the Ethereum network.

When you perform transactions or execute smart contracts on the Ethereum network, you need to pay for the computational resources you utilize. This is where gas comes into play. Each operation or instruction that is done on the Ethereum network requires a specific amount of gas. The more complex the operation, the more gas it requires.

Gas is priced in Ether (ETH), which is the native cryptocurrency of the Ethereum network. Gas prices can fluctuate based on the demand and supply dynamics in the network. The price of gas is usually quoted in terms of Gwei, which is a smaller denomination of Ether.

The concept of gas is essential to maintain the efficiency and security of the Ethereum network. It prevents malicious actors from spamming the network by imposing a cost on every action they take. By requiring users to pay for gas, Ethereum ensures that only valid and necessary operations are executed on the network.

It’s important to understand that gas is separate from the transaction fee. Gas represents the computational resources used, while the transaction fee is the cost you pay to the miners who validate and include your transaction in a block.
