A *Byzantine* *fault* *tolerant* consensus system's whole purpose is to be designed to handle ANY error or malicious behavior from a subset of the nodes and still reach consensus. In NEO, their system couldn't handle the most simple error of one node.

EOS is a necessary experiment with decent performance, semi-centralization and invisible fees.

I am not convinced by Cardano's base-layer security. AFAIK, it's non-slashing PoS (slashing appears to be not decided on yet but unlikely?). I'd be very curious to learn how this doesn't introduce an array of trust assumptions and attack vectors.

PoW is only secure if an attacker can't conceivably amass 51% hashrate. BCH was *never* secure. This hashwar drama is just a symptom of the broader underlying problem. Reorg protections can't fix it. In reality, BCH's best bet is a hash function change or even a switch to PoS.

The power of miners is very limited. Try to stop your central bank from diluting your currency by doubling the money supply in the next 30 years. Impossible. Now try doing it in bitcoin. Easy: just run a full node. We'll run them together. It'll work. That's how we got here.

We have evidence that IOTA intentionally has been misleading their community.

Binance is the world's fastest profitable unicorn. But can anyone riddle me how their $15MM ICO wasn't an illegal securities offering? Some facts about BNB coin:

- ERC20 token
- Offered to the public
- Founders kept 40%
- Clearly sold as an investment
- ICO before a live product

If you are satisfied with a solution where the consensus among a small group becomes canonical for the rest of the network, then both XRP or Bitcoin SV are good solutions for you (most cryptocurrency enthusiasts aren't).

A tailor-made token for a specific use case never makes sense. It goes against the fundamental idea of money. People don't want to have accept payment in things they can't use elsewhere. It's a limitation, not a feature.

To trade in one currency and settle in another requires a liquid market for CVC to other currencies. Who do you think is going to provide that liquidity? Probably someone earning on the spread = hidden fees. For the users, this is the opposite of an optimal economy.

TRX & BTT's primary use case is a public crowdfunded marketing campaign to get Justin Sun's face on as many things as possible and next to as many famous people as possible.

It's just a multisig oracle service. Like @provablethings + weighted average. Similar to @MakerDAO price feeds. Except they require the dumbest 2017-style ERC20 utility token called $LINK for queries, so of course it has a "community".

It's like, you want Kin to be a cryptocurrency. But you don't want users or even the apps that they use Kin to use cryptocurrency nodes. If you don't have that, then there's no trust-minimization, no security and we're back at an in-app points system.

It doesn't help the users of Kin that a couple of large stakeholders somewhere run Kin full nodes if no one is doing it on their behalf. If no one is doing that, it doesn't help them at all that there's a blockchain or that the blockchain is federated.

DPoS chains such as Tron make an extreme trust-dependency trade-off compared to other chains to reach higher throughput. Now, despite having made this brutal trade-off, it can't even handle a single dapp (BTT) without spinning up a separate chain.
