cryptography at @aptoslabs + 🏍️ = ❤️

Rage against the [complex] machine! @aptos Keyless, at a glance, in one slide below 👇
What is an @aptos keyless account? 🧵 It's a blockchain account derived from (say) your Google account and an application (wallet, dapp, etc). It's bound not just to you (e.g., you@gmail.com) but also to the application (e.g., @PetraWallet, or @ThalaLabs, or @VibrantXFinance)

Irreducible's time has come to an end. Long story short, @radi_cojbasic and I ultimately came to the realization that we couldn't sustainably build the kind of deep tech business in ZK that motivated us.

In Peak Human, acclaimed author Johan Norberg examines seven of humanity’s greatest civilizations—and asks: How do we ensure that our current golden age doesn’t end?

If you’re in academia, attending talks or giving talks, a nice discussion on how to maintain productive inquisitiveness 👇
Econ seminar culture is built on the assumption that the audience knows something that the speaker doesn't, and that the speaker values that information. A very important thing the audience knows and the speaker doesn't: Is the speaker making any sense at all? If nobody has any

Reading about Groth-Sahai and liking this hatted notation for groups and their elements 👌

Lord, make me an instrument of cryptographic peace: where there is leakage, let me sow confidentiality; where there is corruption, integrity; where there is misbehavior, verifiability; where there is downtime, liveness; where there is slowness, speed; where there is complexity,

At the gates of heaven, two questions will be asked of you: 1. Have you found cryptography in your life? 2. Have you brought cryptography to others?

* “cyber”security: God help me, how much I despise that word. The moment someone mentions it, you can be absolutely certain there is no principled security in place: it’s been replaced with “cyber”security…

government: recklessly pass data collection laws 💃 lawyers: “comply!!” 🫵 cybersecurity* firms: “the 💸💸 goes here. kthxbye 🤑” computer scientists: continue ignoring that minimizing data collection is part of the ACM Code of Ethics and Professional Conduct (or risk jail)
🪪 ID laws are forcing companies to store massive amounts of sensitive data, turning compliance into a security risk. @Acronis shows how MSPs can close the gaps with integrated cybersecurity, backup, and endpoint protection. ➡️ https://t.co/CR6VApuaWw

I want every week to be like this week!
The week’s proximity-gap papers: - Guan et al. – Polynomial generators preserve distance up to Johnson https://t.co/t1vZXWZK8i - Diamond & Gruen – Random words disprove “up-to-capacity” conjecture https://t.co/pSfz64mfPj - Kopparty et al. – Stronger Reed–Solomon gaps: O(1/η⁵)

[BCGTV15] https://t.co/UIekh017wA [BGM17] https://t.co/OxeEQk7TNo Halo2: https://t.co/RtW64N27si (What’s a complete reference for Halo2 as currently deployed? Maybe the Zcash protocol spec?)

Super-informative breakdown of @zcash’s evolution of ZKP schemes: [BCGTV15] -> [Groth16] -> Halo2 with Bulletproofs i.e., from trusted setups to transparent setups Plus, 👌 explanation of the turnstile mechanism that most fudders don’t (want to) understand 🙄
This is very ignorant. Let's clarify. Over time Zcash has had 3 shielded (private) pools: - Sprout (2016): 0.16% of circulating supply, 6 participants in trusted setup. - Sapling (2018): 4.39% of circ supply, 90+ participants in trusted setup. - Orchard (2022): 25.2% of circ

1/ Excited to announce that @gvamsip, @xosmig, @XiangZhuolun and I have a new paper on building a high-performance mempool for Aptos, which runs directly on the Aptos validators: https://t.co/khHo8zZAGX. The paper has several cool ideas:

Meanwhile, if you read Keonne's letter to the court you see he perfectly acknowledges it 👇 https://t.co/0G80LAlljl

I'm not familiar with the case but, looking at the CoinDesk article, the judge is quoted with saying: > There is no acknowledgement in that letter of the criminal world for whom digital currency is a gift.
Samourai Wallet Developer got 5 years in prison yesterday. What does this mean for devs working on: - ZCash - RailGun - Aztec chain - Privacy wallets - Privacy pools - Zama + FHE Are we just not speaking about this. Is there legal clarity i can't see. Because this case and

Oldie but goldie, this paper shows the importance of cryptography in society, and why ZCash in particular brings hope.
