The newest release of Kulupu is not vulnerable to the DoS vector mentioned in Polkadot v0.8.26-1 release note. You can continue to use Kulupu node version v2.3.0.

We always update all crate packages to its newest possible version every time when we update Substrate, so it just happens that we already bumped past the vulnerable package since last release in October. Watch Polkadot development channels if you want to learn more about this DoS vector.

Here's a thought experiment on what the eth1 to eth2 transition would look like if it happens on #Polkadot (#Substrate).

The main advantage is that not everything needs to be in place in one go (at the transition height). Noticeable improvements can be tested in production, and experienced by users along the way.

Note that this is purely a thought experiment (called "Dothereum"), so there's no plan to implement it. However, we develop and provide the rough specifications as inspirations for both #Polkadot and #Ethereum ecosystems.

For any blockchain that hard forks, its philosophy may eventually suffer the same fate as political promises. The problem is, people change, and no matter by whom, it's people who decide about hard forks.

We've seen coins like ETC abandoning the conservative notion of immutability, or trading scalability with originally promised small block size. Frankly, nothing is either there to enforce the notion of total supply or the promise of staying PoW, because people come and go.

I do still think blockchain philosophy is important, but I don't think it works for hard fork coins. For them, it's a dead end. Any promise or philosophy, if ever made, must be enforceable on the protocol level. Therefore for any hard fork coins, it's just buzzwords.

For hard fork coins, the approach is to stop talking about philosophy and simply drive forward, until the day when it's stable enough to stop hard forking. What's left then will be the actual philosophy of the blockchain, and that's when we can start talking about it again.

The best Ethereum ASIC resistance PoW algorithm would be based on EVM fuzzing. Every block, miners run random (but carefully crafted) EVM programs until the puzzle is solved. Any attempt to build ASICs will inevitably build faster EVM engines. That benefits the whole ecosystem.
