Ofcom will soon have legal authority to compel encrypted messaging apps to scan all user content before it’s sent.

Sovereign code infrastructure.

a new bounty challenge (the third in a row) for 30k $oct and $4444.4444 erc20 usdt has just been added to the repository, we invite vulnerability researchers and mathematicians to participate

ps: please avoid pointless slop reports that serve no purpose…

When you use an AI service, you’re handing over your thoughts in plaintext. The operator stores them, trains on them, and–inevitably–will monetize them. You get a response; they get everything.

we decided to increase the bug bounty reward to 50k $oct and 8888.8888 usd, bounty duration extended by a few more weeks

some insights on hfhe will be posted in the telegram channel (worth subscribing): https://t.co/FPUI2QiOVS

Bloom and cuckoo filters provide fast approximate set membership while using little memory. Engineers use them to avoid expensive disk and network accesses. The recently introduced xor filters can...

Non-custodial wallet ecosystem for the Octra Network with encrypted balances, private transfers, FHE privacy tooling, and developer SDKs.

The tech giant said providing encryption keys was a standard response to a court order. But companies like Apple and Meta set up their systems so such a privacy violation isn’t possible.

what if the new meta is decentralized storage with fhe (already allows working at acceptable speeds in stream)?​​​​​​​​​​​​​​​​

let’s revisit this topic in a couple of months

For quality of life, it is better to err on the side of being an optimist and wrong, rather than a pessimist and right

Quantum computing and blockchains: Matching urgency to actual threats

we added one of the final tests to ensure that the signal and noise are structurally indistinguishable:

easy to run test: "make test-struct-v2"

this paper demonstrates practical lpn attacks up to n approx. 200 (solved in 290 mins), hfhe uses n = 4096 (which puts us well beyond the practical attack boundary with complexity exceeding 2^200)

“prompt engineers” can't even solve a system of equations…
