Thanks.
One thing i understand even less now is, i made a transaction on B3, i opened a pack. it needs to be stored somewhere on B3 network before it is written to Base, because it needs to be batched with all other transactions. The same needs to happen on Base before it goes to Ethereum. There needs to be some kind of infrastructure running for that to happen. There are no classics decentralized nodes responsible for that, so is Coinbase running it?
I assume it must be recorded somewhere as you can't batch stuff in real time :)
ignore the terminology, i probably missed half of how things should be called.
Afaik, the sequencer node(s) are bundling the transactions and then posting them bundled to Ethereum/Base from Base/B3. Within the timeperiod between a transaction being run on the rollup and it being submitted to Ethereum/Base, a transaction is technically not confirmed, only afterwards. Some blockchains only run 1 sequencer node, which means, there is some trust involved in the sense that the sequencer node isn't censoring transactions or delaying them. However, afaik, there are also projects trying to decentralise the sequencer nodes.
