## Summary

The author of this post argues that Ethereum's network is more secure than Bitcoin's, and that Bitcoin's network security matters for BTC as an asset. The post claims Bitcoin has real centralization under proof of work, weak censorship resistance, no finality, no long-term security budget, no client diversity, and vulnerability to cartelization and spawn camping. It credits Ethereum with home validators, censorship resistance tested against OFAC sanctions, finality backed by tens of billions of dollars, tail issuance, and more than 10 clients. It says Bitcoin's monetary policy certainty is its only advantage over Ethereum and calls the security budget issue its weak point.

## Article

BTC and ETH as assets are secured by their respective networks - Bitcoiners like to think that the Bitcoin network doesn't matter for BTC, but it most certainly does.

Bitcoin as a network has real centralization with PoW, is not very censorship-resistant, has no finality, has no long-term security budget, no client diversity, no answer to cartelization, can be spawn camp attacked to death and so on.

Ethereum as a network is much more decentralized (actual home validators), extremely censorship-resistant (tested at scale with OFAC sanctions), strong economic finality (tens of billions of dollars worth), no issue with its long-term security budget (has tail issuance), very healthy client diversity (10+ clients), much harder to cartelize (economies of scale aren't as rewarding with PoS as they are with PoW), can't be spawn camp attacked because it has slashing.

The only thing BTC has over ETH is the relative certainty around its monetary policy but this is actually the Bitcoin networks Achilles heel and will lead to its eventual downfall (this is the security budget issue).
