Blockchain is still plagued by a number of challenges, with some of the main issues being transaction bottlenecks, scalability limits and high levels of energy consumption. Can blockchain transactions be reversed? No, blockchain transactions can’t be altered after being initiated. This is due to...
but private blockchains can also hold a variety of other information like legal contracts, state identifications, or a company's inventory. Most blockchains wouldn't "store" these items directly; they would likely be sent through a hashing algorithm and represented on the blockchain by a token...
5.1 Block Truncation Coding 5.1.1 Original Block Truncation Coding Algorithm Block truncation coding (BTC) is a simple lossy image compression technique to compress monochrome image data, originally introduced by Delp and Mitchell [1]. It achieves 2 bits per pixel (bpp) with low computational compl...
8. Change the consensus algorithm in your fork To better understand the differentconsensus algorithmsin blockchain, try and change which one your own blockchain fork is using. 9. Set up a testnet for that fork and put it online A testnet is a blockchain which doesn’t require you to spen...

Bierling proposed a hierarchical block-matching algorithm with variable block size. Firstly, a large block size is used to find the major component of the displacement. This rough estimate, which is very robust due to the large block size, serves as aninitial valuefor lower levels of the hiera...
CBC is among the most used methods for encrypting large messages. It is the more secure successor of ECB. In ECB, the plaintext is divided into blocks (the algorithm specifies size), and each block is encrypted into a ciphertext block. Since identical plaintext blocks always encrypt into th...
One of the properties of the cryptographic accumulator is completeness, that is, the witness of the output of any call sequence through the scheme algorithm, because the state of the set at the time of witness generation is correctly verified with an almost negligible probability. Completeness. Le...
