Learning from the Chronos project

[s1na]

The great ChronoLogic team is working on a similar concept, called chronos.

Short intro

Chronos aims to achieve conditional execution, by having the user deploy a ScheduledTransaction contract, which contains the logic for checking whether the required condition (gleaned from the state) has been met. Upon seeing the new ScheduledTransaction, TimeNodes monitor the contract, and publish the signed transaction from the user to the network, when the condition is satisfied.

Analysis

Here's an attempt at learning from the benefits of their approach:

• There's no need for the TimeNodes to provide proof, as the state can be checked on-chain on execution.
• Condition is a view function, therefore no gas has to be paid for checking.
• Signed transaction from users removes the need for using smart contract based wallets to do actions on user's behalf.
