EOS launch is delayed sine die, it looks more and more vaporware to me. 27 masternodes is not decentralized and is fragile. The longer the time, the better Ethereum looks compared to other "leading" projects.
As I understand, EOS was launched today after the voting process iscomplete?
Yes it is not decentralised at all. Only a fool will say EOS is decentralised. It is more like a banking system than a blockchain
The Block nodes have full control on the network
Weird, I read yesterday or two days ago on investing.com that the main net launch was suspended. I think they "had" to launch the main net just to keep credibilty, or should I say token value. Anyways, the code seems to be very buggy, therefore I would not be surprised to see attacks on them. Once ethereum will upgrade its scalability, I really can't see any blockchain being competitive against it.
Other blockchains will have advantages in some aspects, eg anonymity for CN based ones, or cheaper fees, but globally ETH is leading.
