A problem is not a sign the universe is against you. A problem is a conflict between explanations. Since reality has no contradictions, a problem means your knowledge is flawed. Problems are invitations to improve your worldview. 4/15
A BLS signature is simply: σ = sk·H(m) This makes the signature linear in the secret key. That is intentional. When verifying, we check whether the secret key affected the message and the public key in a consistent way: e(σ, G₂) == e(H(m), pk) If the signer doesn’t have…
BLS uses a bilinear pairing: a function that takes one point from G₁ and one from G₂ and maps them into a third group G_T: e : G₁ × G₂ → G_T The key property is bilinearity: e(a·P, b·Q) = e(P, Q)^{ab} It means the pairing preserves scalar multiplication on both sides.…
The entire BLS signature scheme is one line of math: e(sk·H(m), G₂) = e(H(m), sk·G₂). Why this equality enables multi-signature compression, a thread: (1/)

Hey I’m glad everyone’s excited about Zcash again! It’s one of the coolest things I’ve ever worked on in my life.
I'm excited to announce that I'm hiring a team focused on shipping Tachyon in Zcash! If you're a Rust engineer who is passionate about privacy, crypto, and high assurance software -- and if you're interested in working on something meaningful -- please get in touch with me.
Over 30% of all Zcash are now shielded! Wow
