amazon will lose sponsored ad if AI agent keeps doing shopping as they will just ignore the ad. it’s a biz opportunity but only workable if you can convince Amazon or charge for agent shopping. monopoly is not helpful for technology advancement
JUST IN: Amazon blocks Meta’s Muse AI agent from shopping on behalf of users, citing unauthorized access and privacy concerns.

my @Muse agent just made a phone call to make a reservation for me this morning and he figured out this task by checking my calendar. i gave him approval of go ahead. no setup needed, that’s the beauty. i remember it was google demo a few years ago, but now @meta made it working. personal agent is going massive adoption soon.

I read the recent statement on AI and mathematics signed by Terence Tao and 24 other Fields Medalists. mathandai.org As a software engineer and math enthusiast, not a mathematician. I had a slightly different reaction. A short thread:

8/ The risks are real: attribution, independent verification, concentration of compute, and the training of future mathematicians all matter. But I don’t think the answer is simply to preserve the old workflow. New tools usually require new workflows.

9/ Maybe the right conclusion isn’t: “Process doesn’t matter anymore.” It’s: “The process itself is being redefined.”

Goodbye, Poseidon! An epic 8-year, 8-figure rabbit hole in post-quantum cryptography reaches its dream conclusion. The Ethereum Foundation is abandoning Poseidon for L1, pivoting to SHA or BLAKE. This milestone unlocks ultimate security for lean Ethereum and foreshadows a golden era of hash-based cryptography. Since 2018, the Ethereum Foundation has invested in magic cryptographic bricks, so-called "SNARK-friendly hashes". In 2019, Poseidon was born. It held strong and became the dominant SNARK-friendly hash, securing billions via zkrollups and zkVMs. In a stunning reversal, breakthrough SNARK designs show that SNARK-friendly hashes aren't necessary after all. Off-the-shelf traditional hash functions like SHA2 and BLAKE2s can now match Poseidon in a SNARK. In hindsight the key was not SNARK-friendly hashes, but hash-friendly SNARKs. The secret is doing maths over the smallest prime number: 2. So-called "binary fields" natively speak the language of bits, aligning with the boolean operations inside traditional hashes. This is a stark departure from "prime fields", where awkward large-prime arithmetic makes bit manipulation painfully expensive. We're talking sci-fi cryptography. 1M traditional hash calls proven per second, on a laptop. Just 100x overhead vs native CPU boolean compute. Nobody predicted such performance, not even the handful of binary-field visionaries. Hat tip to the research geniuses: Jim and Ben with Binius in 2023; Ron, Benedikt and William with Flock in June. With SHA2, the lean aesthetic of minimal assumptions reaches its climax. The EF's principled stance on pure hash-based cryptography has aged like fine wine. We now enjoy foundations the world can trust for decades and centuries, foundations worthy of the dream of an internet of value. Speed of deployment is a secondary win. There's no longer a need to wait years for Poseidon cryptanalysis to bake. Emile and Thomas from the EF post-quantum team are moving at breakneck speed with binary fields. The strawmap now points to a production-grade leanVM in 2027, with CL, DL, EL deployments in 2028. As AI becomes exceptional at cryptanalysis, the contrarian bet to avoid riskier structures like lattices and isogenies is visibly paying off. The past weeks have been brutal. Lattice-based "HAWK" and isogeny-based "SQIsign", both signature schemes in NIST's Round 3, have suffered blows. Sources I trust say more blood is coming. On AI, the open autoresearch trend kicked off by ECDSA[.]fail is spreading fast, with amazing outcomes from zk[.]golf and SNARK[.]fast. Days ago SNARK[.]fast crossed 1.8M BLAKE3/sec proven on an M3 Max. Stay tuned for fresh autoresearch challenges dropping tomorrow. Also tomorrow: Ethproofs call #10, dedicated to binary fields. Possibly the most noteworthy Ethproofs call yet. Experts leading the charge will present the future of hash-based SNARKs at 2pm UTC. What an incredible time to be alive. To witness history, DM me for a calendar invite :) Today I can confidently claim that hash-based cryptography has won out for blockchain post-quantum signatures. SNARK succinctness compresses arbitrarily many signatures into one small proof per block. SNARK flexibility yields k-of-n threshold signatures, complex multisigs, and more. Ultimate security. Uncompromising performance. Full programmability. Believe in something. Believe in hashes.

After spending the last two years building the MegaMafia, we’ve decided to sunset the program. While it was a success in many ways, we believe that the program was built on assumptions that no longer hold. Here are some reflections, and what’s coming up next. > We had real conviction in Mafia founders, and have gone above and beyond in standing by their side to bring their products to market. Some examples include: restructuring the GTE leadership team during critical moments just one month after their initial pre-seed raise, offering to buy out Noise's investors when they tried to push out the CEO, and played a crucial role as they pivoted from their initial prediction market idea, and merging the Tenten and HitOne team after seeing the synergy between the two. > Across both cohorts which in total included 20 teams, we lent our reputation and networks to founders so they could go on to raise over $80m in funding in pre-seeds, seeds, and series As. We kept the MegaETH’s raise to a minimum so investors can get more skin in the game with the Apps directly, rather than the protocol. > For teams that had difficulty in raising when the market turned bearish, we extended resources, engineering bandwidth, and actual capital (e.g. six figures in audit for Avon) so they could make it to Mainnet. We did it solely to help founders see their vision through. > We set the product vision for 5 teams and supported their initial builds before eventually facilitating their fundraises from leading tier-1 and tier-2 funds. > We spent significant cash (in the millions) bootstrapping teams’ DeFi requirements, through market-making support, direct lending, and other liquidity related needs. > We hosted 5 large-scale in-person events (New York, Brussels, Bangkok, Singapore, and Seoul) so MegaMafia projects could meet investors and community members from around the world. In many ways, the MegaMafia was the best incubator of this cycle. But very little of that value has trickled to Mega. In fact, most of those applications are no longer being built with us. At the time, we intentionally took no equity, governance rights, nor economic value because we wanted people to be genuinely bought into the Mega vision and the power of our technology. While we will continue to support existing MegaMafia projects, there will no longer be MegaMafia 3.0. What’s next? Our ecosystem goal going forward is to support teams building OMEGA applications, apps that are only possible on MegaETH, using our wallet infrastructure and stablecoin. More importantly, we're redirecting the energy we were lending to third-party builders into our own first-party applications: consumer-grade apps, built directly by us, for the people we're trying to serve. Where MegaMafia was indirect, betting on other teams to build value we'd eventually capture, first-party apps let us build direct relationships with end users ourselves, with all the upside and accountability that comes with owning the outcome. We're aiming for faster feedback loops, with insane focus on accruing value directly to the protocol.

Real AI adoption needs domain expertise, that's why FDE is needed everywhere. It's a new kind of job opportunity, but I don’t know if new grads can get the job. wdyt?
