I have a private network created using geth and I want to use it as a decentralized database. Currently, I'm testing the network using 3 nodes which one of the nodes as a validator (hence only one sealer).
At first, I thought that having more sealers will make transactions faster to be mined but there could be problems with that like all the sealers stop mining because they wait for each other to sign the block and transactions are stuck in a pending state.
Using only one sealer is not posing any problem about stuck transactions. But, I'm worried this will be posing another problem I don't know. Is this kind of private network okay? I feel like security problems could rise from here.
