Blocks without transactions question

do you know why are there blocks without transactions? blocks are 600k transactions are 300k

Not sure what you mean Ikelemen… blocks are every 5 seconds… and not every block has transactions…

so what is the role of a block without a transaction?

While it might seem more efficient to create blocks only when there are transactions to be processed, the regular production of blocks ensures the blockchain remains secure, functional, and prepared to handle transactions at any moment, thereby maintaining the ledger’s integrity.

In the IBFT model on the Electroneum Smart Chain, we achieve single block finality. Regular block production reinforces this guarantee by continuously affirming the network’s current state and the consensus among validators. Every 5 seconds, the validators reach consensus on the state of the blockchain… waiting for a random period loses that reliability and also increases the chance of Byzantine faults.

Having regular blocks encourages validators to maintain their nodes and ensure they are reliable, active, and responsive. It also makes the network predictable for users and developers.

I believe there are also certain types of attacks that are mitigated by having this consistency. Allowing block creation to be altered by controlling transaction flow could be manipulated, which presents a risk. Consistent block production helps protect against such manipulation, ensuring a fair and secure blockchain environment.
