Ethereum tries to be a currency and a "world computer" at the same time - this is not going to work, the "world computer" part will compromise the currency, and the currency will be holding back the "world computer". Ethereum is only getting more and more centralized because of their bloated blockchain, centralized development and now PoS consensus. And the new coins like TRON are borderline scams, because all they do is make loud statements without achieving anything.
That's an interesting statement.
Though we should probably separate each networks from their application(s).
- Bitcoin network is exclusively applied to BTC the currency
- Ethereum network is applied to ETH the currency + to storing and running dynamic programs on top of the network.
Now, regarding decentralization, there are actually 2 main types of it:
- Of the network via the validators and consensus (51%)
- Of the (circulating) supply (which bring us back to scarcity)
How allowing programs to run on top of Ethereum Network is having a negative effect on its decentralization (and its ETH currency) in practice ?
