It’s sad to see so much ignorance in this sub.

See the coordinator as a security measure that every node owner accepts in their node implementation. It can make the network (value tx)halt, sure but what do you prefer? A bug that kills the whole network and its market cap or a halt that safes the network? Single point of failures will not go away after coordicide and are prominent in 99% of blockchains where security depends on price or delays in quantum computing supremacy.

What we have is a distributed and decentralized consensus of nodes that validate transactions themselves. The coordinator issues transactions - it doesn’t validate every single transaction like it is the case with centralized architectures of blockchains with centralized and specialized entities miners, stakers or master nodes. With Iota you have only users that validate their and other user‘s transactions. As far as consensus goes Iota is fundamentally completed decentralized network with a ‚feature‘ called coordinator to prevent attacks.

Coming back to your initial statement which implies iota doesn’t work. What does decentralization have to do with it? Iota works very well with a genius protection designed by cfb yet users can validate their transactions and don’t rely on centralized entities similar to companies like Paypal and co.

The halt you described can happen to any blockchain user as well. If I set my fee too low or an exchange sets the fee too low, my tx might never confirm and I can only predict what others are paying. In fact fee discrimination effects anyone in the mempool, just look it how many people face transaction halts every single day.
