Review of the federated learning problem As mentioned above, in 2016, Google proposed a new method for training the input method model, called "federated learning". As time goes by, federated learning is no longer a simple solution to the Googl

Premo is mainly implemented based on BitXHub's own gosdk, which is easy to expand and maintain. This article mainly focuses on the three aspects of functional testing, performance testing and automated testing to give an overview of Premo's testi

Although the performance of HVM has been greatly improved compared with EVM, due to the large number of bytecodes, the execution performance in the interpretation execution scenario is very limited. In order to solve this urgent problem, we introduced th

Privacy comparison refers to obtaining the magnitude relationship between the two parties without revealing the specific values ​​of the two parties. This article mainly introduces a privacy comparison protocol with relatively high efficiency at pres

We have learned that distributed systems generally achieve consistency through the principle of state replicator [1]. The core idea is that all replicas in the system run the same state machine, as long as all replicas start with the same initial state a
