In theory aeternity transactions are written to the blockchain in 3 seconds or less.
In practice however, how long does it really take a transaction to become “effective”?
Let me expand on this. Most exchanges consider btc txs to be finalized after 6 confirmation at least, dash may requires 20 confirmations, doge required 100 and, as an extreme example, as of right now energi requires 5000 confirmations due to some network instability.
however, Dash has instant send that allows merchants to consider a transaction valid in way less block confirmations.
it is clear to me that aeternity has times as fast as the dash instantsend without needing masternodes, but how secure/safe is it? if I were a business and I got paid in aeternity would I need to wait for it to be in the blockchain? for 7 confirmations? for 20?just one?
I don’t even really understand completely how aeternity manages splits, or if any split chain has had longer blocks. I have seen orphan blocks and transactions moving from one block to another but never a full revert on a given transaction (though I mamight be wrong or may have missed it) since the chain is already mature enough is this somethign that can be calculated?
