cannon VS clientdiversity-org

It's important to note however that OP still doesn't have 'fraud proofs' (for that we're waiting for 'Cannon': https://github.com/ethereum-optimism/cannon) or an 'escape hatch' (that would allow users to recover funds if the L2 validators stop functioning). Risk management is vital in this game so it seems essential to highlight these absences.

In the meantime, Arbitrum One is still not in its final form, it'll be upgraded to Arbitrum Nitro which is basically a rewrite of some large components. Optimism has fraud proofs disabled while they are rewriting them (their interactive on-chain fraud prover still appears to be in heavy development). Both have training wheels / guardrails and are currently centralized (i.e. you can't run a sequencer yourself).

Alessandro said it'd be a few days before he can get me a data endpoint, but once that happens I'll have clientdiversity.org updated in a day or 2

Ethereum is the most decentralized transaction ledger in the world, with thousands of nodes distributed across the world, and more client diversity than any other blockchain that I'm aware of:

The move to Proof of Stake has also made solo validation accessible to parties other than large pools.

there are guides on https://clientdiversity.org/

Large number of nodes does not equal decentralization. In Ethereum, like all other networks/countries, power tends to consolidate. All the consensus power is consolidated to 1-2 entities.link Hedera is already far more decentralized.

Apparently that’s the case, yes: https://clientdiversity.org/ though the source says „data might not be 100% accurate“, but I guess it’s sure geth dominance is down.

Execution clients only run GETH. Client diversity isn’t even great per eth foundation: https://clientdiversity.org

10+ separate companies implement the protocol in 10 completely different independent code bases https://clientdiversity.org/

As I said this is the second time I did this "report" and asked for better sources the first time as well. In the end I did my best to find reliable sources, but even back then I really wasn't sure if these numbers are correct. And if you look at https://clientdiversity.org/ there are even two data sources you can choose that really differ... so +1 to the irony of our industry...
