HElib
HElib is an open-source software library that implements homomorphic encryption. It supports the BGV scheme with bootstrapping and the Approximate Number CKKS scheme. HElib also includes optimizations for efficient homomorphic evaluation, focusing on effective use of ciphertext packing techniques and on the Gentry-Halevi-Smart optimizations.

Project mention: And the Earn It act is back in the US. Third times the charm to crush privacy? | /r/linux | 2023-05-06I'm one of the maintainers of Crypto++, https://cryptopp.com/.
The bug occurred when a multi-path payment interacted with an AMM synthetic offer, and the synthetic offer required to fulfill the payment exceeded the AMM pool size. In this case, the payment engine attempted to use the single-path strategy to back-out the maximum liquidity available to swap against the pool. Although this condition was properly detected, there was an error on how the payment engine resized the synthetic offer to consume liquidity only up to the AMM size. Instead of using the actual swap rate, which represents the cost of fully swapping one side of an AMM pool, the new synthetic offer’s exchange rate was incorrectly set to the spot exchange rate of the AMM (that is, the rate it takes to execute an infinitesimally sized order). Consequently, an AMM operation that should have been expensive became relatively cheap, effectively violating the constant-product invariant of the pool. In this state, another user could deposit funds into the drained side of the pool, generating a large number of LP tokens and taking ownership of the pool. Now that the fix amendment is active, the team has opened a PR with a unit test demonstrating this behavior.
Project mention: What are the current hot topics in type theory and static analysis? | /r/ProgrammingLanguages | 2023-05-08Secure computing. This includes Fully Homomorphic Encryption AKA FHE, of which there is a language/compiler which just got released and Google's older FHE compiler. FHE is probably more "compiler" than "type system", e.g. Google's compiler works on C++. Also Security Type Systems which include Oblivious data structures and Oblivious ADTs.
Project mention: On Intel SGX, is it possible to set an executable running such that you, the operator, cannot decrypt its state? | /r/crypto | 2023-12-07
I'm running a tor bridge on my home proxmox box, and I'm interested in running an i2p node as well but I have no experience with this. From what I was able to gather the easiest way is to install the i2pd .deb (https://github.com/PurpleI2P/i2pd/releases).
Project mention: Ask HN: What are some of the most elegant codebases in your favorite language? | news.ycombinator.com | 2023-06-17
I know that cryfs[1] is resilient to at least the first of these, and possibly the second as well. I don't know if cryfs allows to modify the base directory while the filesystem is online, if it does then it might already be a better solution for syncthing, if you only care about Linux.
On the flip side syncthing could incorporate cryfs's base directory format instead of their home-grown one.
You can actually write zkps in pure Rust, but there's not currently any blockchain integration: https://github.com/risc0/risc0
Download the official Qtum wallet from qtum.org and you can stake (or delegate staking) directly through your wallet
Project mention: Concrete: Converts Python programs into homomorphic encryption equivalent | news.ycombinator.com | 2024-03-09
ManySAT: http://www.cril.univ-artois.fr/~jabbour/manysat.htm
It shares short conflict clauses between parallel solvers and achieves superlinear speedup in some cases, e.g., 4 parallel solvers solve faster than one forth of the single solver soolution time.
Short conflict clauses are rare so there is little communication between solvers required.
CryptoMiniSAT: https://github.com/msoos/cryptominisat
Author's goal to have solver that is good in computing range from single CPU up to cluster. Judging from CryptoMiniSAT successes, he has mostly reached the goal.
Peter continues his work on walletdb refactoring (PR #1239), which optimizes performance by using a single instance of CWalletDB. It is about 90% done and is estimated to be done by the end of the week.
