#exSat is not an L2 solution like Ethereum. exSat has independent consensus and is essentially a side chain, so it will not send transactions to the BTC side for confirmation (BTC does not support smart contracts and has no verification capability)
But because exSat is fully synchronized with BTC data, exSat can replace the BTC network to do L1 and verify or confirm L2
This is why exSat is called Docking Layer. exSat itself is not L2, but it can be used as BTC's L2
Because #exSat has powerful RAM, only we can synchronize and store the status data of #BTC
