Off-topic, but kind of relevant too. IOTA is currently under fire by people calling it a centralized blockchain because the blockchain is currently being temporarily ‘turned off’ due to an ongoing investigation of an attack:https://twitter.com/iotatoken/status/1227990537799524352?s=21
I really appreciate the decision NEM Foundation and core devs took for not forking after the Coincheck hack. Hopefully Symbol will still not have this ‘feature’ to turn-off or pause the blockchain for whatever reasons. A non-disruptive feature like transaction ‘flagging’ is in my opinion still acceptable.
the only somehow central part is the supernode payouts as they are not part of blockchain code but voluntary paid coins managed not by in node included mechanics but instead vorultary extra installed software tp check node performance and central payouts towards nodes who successful pass performance requirements
Yes. Generally speaking, this is also how some of the blockchains work. Including IOTA, wih their ‘Coordinators’ which, among others, are responsible for block validation. But the problem is that because of a centralized control, the blockchain can essentially be ‘paused’ whenever there is a call out to that.
same as on bitcoin if a major event happens that cry for an urgend update even then node operator need to manual update and choose if they happy with the proposed upgrade or they wait for another solution that they support more
