    How can the 100 DAI anonymity set be 37 when the contract holds only 1000 DAI? Shouldn't it be 10?

    I understand that the writer's intended audience might not really care about the differences of pseudonymous and anonymous, or how digital signatures work, but using bitcoin's bare-bones cryptographic assumptions as an argument against it is very odd. Maybe I'm nitpicky though

    Reading Burton G. Malkiel's latest edition of "A Random Walk Down Wall Street" and I hit the section about cryptocurrencies. While I expect the book to have more insights than just "put your money in index funds and avoid bubbles", I got pretty cracked up by the marked parts

    All ZK-Layer2s require providing a witness showing your balance is enough at the latest state in order to have instant withdrawals. If you go offline with a witness from block 10 and come back in at block 100, you can't withdraw unless a peer sends you a witness from block 100

    DAOs: Fancy access control lists for smart contracts. I want to stay open minded and believe that they may reduce costs and automate corporate governance in the future, but at the moment they seem like a place where securities are being masqueraded as "utility tokens"

    This can have benefits (c.f. Parity wallet hacks) for both security of your script/contract (CHECKSIG vs CHECKMULTISIG, simple signature check vs chaotic multisig contracts), for improving scaling since smaller txs means more txs can fit in a block, and of course fees

    Note that all multi party computation wallets are basically pushing the complexity of a multisig from on-chain to off-chain. It is still a multisig, but the on-chain fingerprint looks like 1 signature. Do not fool yourself into believing there is any system that's unhackable

    Baby SNARK (do do dodo dodo)! A tutorial on the simplest SNARK, its implementation, and most importantly its soundness proof. Comes with code and writeup still rough around the edges, but pls enjoy

    There is a new post on the Writing an OS in Rust blog: It builds upon the previous post about heap allocation and explains how different kernel allocator types can be implemented from scratch.
