I am coding an app where users can deposit ether into their accounts and do stuff with it (Im using web3.js
and geth
). However I would like to have everyone deposit into one single account, and then have a database that knows how much of the total pool of ether in the single account belongs to each person.
I was wondering if there was a feature in Ethereum where users would be able to send a message along side their transactions? So that a specific code could be given to the user who is making a deposite, and once the serverside code of the app sees the code, it can know who sent the ether.
QUESTION: Does this functionality or a similar one exist?
