the same point or do some of them go earlier than others?
They go to different point in time, but none of them go to beginning. Not losing record is primary function of mirror node explorers in any ledger. Network is not on some giantic tx volume since beginning but still not searchable.
Do the mirror nodes not download the full history when they are started?
Question for all 4 of them, as none of them work as it should
Eventually mirror node based explorers will emerge as businesses...but it is a problem now since state proofs are not in place. State proofs will replace the need for comprehensive histories going back to Genesis...the main reason that the full chain back to Genesis is important in blockchain is because of the lack of finality. Hedera has finality
History need to be there regardless it is requirement by law, you cannot erase it. Finality and settlement (block) are two different things in blockchain, finality is below 1 second in Bitcoin hence 0 conf works and it is secure. As in other reply I was told to wait till September, so will wait.
Doesn't bitcoin depend on the longest chain principle? It is theoretically possible for a single node to build malicious fork that becomes the longest chain right? This was demonstrated on Ethereum Classic. On Bitcoin or Ethereum it is too difficult to pull it off. But a quantum supercomputer could. People traditionally wait for confirmations in bitcoin don't they?
Finality is never achieved truly on btc
BTC is not Bitcoin, they have invented and follow their own chess rules.
Perhaps you can clarify the difference? My sense is for the vast majority here BTC = Bitcoin and we're starting with different base assumptions.
I think they're just trying to sound smart. For all intents and purposes everyone treats the two as interchangeable
