Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
SEAL
- On Intel SGX, is it possible to set an executable running such that you, the operator, cannot decrypt its state?

Fully Homomorphic Encryption by Google
FHE has been around for a while now, IBM: https://github.com/homenc/HElib and Microsoft: https://www.microsoft.com/en-us/research/project/microsoft-seal/ both have their own (much more mature) FHE implementations.

Fully Homomorphic Encryption (FHE)
It's really great to see more big companies getting into this game, ease of adoption is really the key here.
When it comes to FHE, there are 3 underlying paradigms you can target with compilers:
1. boolean circuits, where you represent your program as encrypted boolean gates. The advantage is that it's as generic as it gets, the drawback is that it's very slow. TFHE is great for that, and it's what is shown here.
2. arithmetic circuits, where you represent your program as a combination of encrypted additions and multiplications. This goes really fast, but you are quickly limited in terms of usecases because you can only do a certain number of arithmetic operations. CKKS/SEAL targets that: https://www.microsoft.com/en-us/research/project/microsoft-s...
3. functional circuits, where you represent your program as a combination of homomorphic functions. Advantage is that you can do very complex things like deep neural network, the drawback being that you have limitations of the bits of precision for the computations. Concrete targets that: https://zama.ai/concrete/

Would you pay for querying a postgresql database in such a way the server never learned what row you queried for?
Case 2: the encrypted case. You would be encrypting the data itself, so each cell in your database would be encrypted, the filesystem, the tables, the database, and every other aspect of postgresql is left exactly the same. As a matter of fact, you would install this the same way you would install every other postgresql extension. Just run "make install". The only dependency is Microsoft SEAL(https://github.com/microsoft/SEAL) which is open source and you download it and install it from source as well. That is it.

What are some alternatives?
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.
