I have a simple contract that receives any amount of ETH. The contract keeps those ETH certain amount of time until it realeases the funds to it's original owner.
I have defined which block represents the moment of release.
The only thing that I don't know how to do is, how to tell the contract: "now we are in the specified block, release those ETH".
I mean, the contract is not reading the blockchain continuously, which is the way to tell that info to the contract automatically?
