Previously, we used python to implement compression and decompression Based on 256 characters of Huffman and the paradigm Huffman.Program. Python is indeed suitable for quick implementationAlgorithmIncluding the implementation of the Framework

First of all we need to understand what CODEC means. It is Coder + Decoder = Codec, which is the encoder decoder. That is, the encoder is also the decoder.Website address: http://commons.apache.org/proper/commons-codec/Apache Commons Codec (TM)

Objective The first two articles simply implement blockchain creation and proof of workload, but they are all in memory. The actual blockchain should be stored permanently, which makes sense. A permanent blockchain storage is started

Original address The original address https://jeiwan.cc/posts/building-blockchain-in-go-part-3/introduction So far, we've done a block chain with a work-proof system, so it can be dug. Our implementation is getting closer to the fully functional

[Guide]What are the differences between data compression and deduplication? In practice, how can we apply it correctly? I have not studied the principles and technologies of Data Compression before, so I did some homework, read and sort out relevant
