Faucet

In order to submit a transaction to the blockchain, a fee needs to be payed to cover for the computational power used to mine this transaction. Thus if an account has not enough credit to pay for this fee transactions will not be mined.

A Faucet service is a pre-funded account, held by system administrators, that can be used to micro-credit accounts at the moment of their creation and/or before a transaction is signed. Using this service will ensure that all accounts submitting transactions have enough funds to pay for the mining of those transactions.

Note

In the context of Orchestrate The Faucet Service can be used by:

  1. Tx-Signer worker to micro-credit users’ accounts at the moment of their creation, as a one-time operation.

  2. Tx-Crafter worker to micro-credit users’ accounts when submitting transactions, as a recurrent operation.

Tip

On Ethereum, the computational effort needed to execute an operation is measured in Gas, and this Gas is payed in Ether or Wei. Wei is the smallest denomination of ether, the cryptocurrency used on the Ethereum network.

1 Ether = 1,000,000,000,000,000,000 Wei (1018).
