Designing Blockchain #3: Cryptography and Wallets
Intro In the previous article, we explored how blockchain manages accounts and state transitions through transactions. However, we left a critical security gap: anyone could create a transaction claiming to be from any account. This article addresses...

Driving the evolution of AI from the cloud to the chain.
Love how you’ve explained the practical uses of Ed25519 and BIP-39 for wallet security. The elegance of cryptography often gets buried under buzzwords, but this piece brings it back to fundamentals.
It’s exciting to see how these same principles can extend beyond transaction security, for example, powering verifiable AI computations and on-chain logic where ownership and trust are built directly into the protocol. The overlap between cryptography and distributed computing is where the next big leap in blockchain could come from.
