Hi. Ittay here, one of the authors.
Bitcoin-NG is precisely as decentralized as Bitcoin. Whereas in Bitcoin, a miner is elected via a distributed lottery to determine the transactions that took place in the preceding 10 minutes, in NG, a miner is elected via a distributed lottery to determine the transactions that take place in the following 10 minutes.
- Natanael_L 11y agoHow are leaders discouraged from attempting network isolation attacks? How do nodes handle the sudden peaks in traffic when selected on the "round-robin" PoW scheme when load is high? How do the network handle the ever shifting connections (with TCP session setups and all), what's the topology? Are you considering the effect of the current leader being attacked by 0-days,what do that do to the network when it gets hijacked? What if the leader drops off or otherwise have connectivity issues?
- wyldfire 11y agoThe effect of an unreliable or malicious leader is fewer transactions than possible or unfair prioritization of transactions, but limited to a single (10 minute) block. Seems like if it were an uncommon event it should be not-very-consequential. Then again, if the lottery likelihood is a function of hashing power then maybe it's not so well distributed.
- Natanael_L 11y agoBut if the leader signs conflicting transactions, which wins?
