SHA-3, on the other hand, is another extreme in the algorithm spectrum. It's extremely friendly to ASIC, and it's even the most pro-ASIC algorithm in the FAMILY of SHA algorithms that are extremely friendly to ASIC (SHA-256, SHA-512, etc.).
On December 21, 2012, Blake's re-release product, BLAKE2, was released. It was created by Jean-Philippe Aumasson, Samuel Neves, Zooko Wilcox-O'Hearn and Christian Winnerlein to replace the widely used MD5 and SHA-1 algorithms. Blake2b is faster than SHA-3, SHA-2, SHA-1, and MD5 when running on 64x64 and ARM architectures. Although BLAKE and BLAKE2 have not been standardized as SHA-3, they have been used in many protocols, including the argon2 encryption hash, because it provides high efficiency on modern cpu. Since BLAKE is a candidate for SHA-3, both BLAKE and BLAKE2 provide the same output size as SHA-3 -- including configurable output sizes.

SHA-1 and SHA-2 are two different versions of the SHA algorithm, both of which are constructed and signed in different lengths, but SHA-2 can be understood as the successor to SHA-1. Bitcoin's SHA-256 belongs to sha-2's 256-bit usage, and when I wrote Bitcoin in 2008, I didn't take into account that SHA algorithms could be cracked so quickly, but fortunately later the various digital currencies adopted more and more difficult cryptosensy, and you could go back to my previous series of "How Cryptocurrencies Cryptocurrencies".
SHA-3: In the opposite direction (ASIC-friendly), SHA-3 is the most acceptable option for the community. We've seen giants like Bitete continental develop specialized mining machines for SHA-256 and Scrypt algorithms for a long time. The sha-3 is characterized by its real simplicity, so simple that in the SHA-3 algorithm chip competition, small companies and large companies to maximize the power gap is reduced, which helps to prevent the monopoly of computational power. Even for GPU miners, SHA-3 may keep them profitable at low risk.
SHA-2: Released in 2001, including SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, SHA-512/256. To date, there have been no effective attacks on SHA-2.
Hash values are 256-bit, 384-bit, and 512-bit, respectively, called SHA-256, SHA-384, and SHA-512, and these algorithms are collectively known as SHA-2.
SHA 256 is one of the SHA series algorithms, a hash algorithm designed by the National Security Agency and published by the National Institute of Standards and Technology, known as SHA 256 because of its summary length of 256bits. SHA 256 is one of the safest ways to protect digital information.
Common algorithms: MD5, SHA-256, SHA-512, RIPEMD-160.
Dogecoin (DOGE) is committed to becoming a cryptocurrencies of real practical value like a currency. Dogecoin is now the second most popular "tip electronic currency" on the U.S. Internet
In this way, the internet legend shifted from Doge to Dogecoin. On December 6th, on BitcoinTalk, a well-known Bitcoin forum, a new member named Dogecoin posted a message about a competitive coin named Dogecoin, which Chinese translates as a dog coin, cute and memorable. The title of the post is Dogecoin - very currency - many coin - wow - v1.1 Released, and the style of the teaser is in line with Doge's.

A series of password hash functions are published, including SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512.
MessageDigest sha - MessageDigest.getInstance ("SHA-256")
The algorithm actually used by Bitcoin software is the SHA-256 algorithm, which is a kind of SHA algorithm. In 1993, the National Institute of Standards and Technology (NIST), designed by the National Security Agency, released the first SHA password hash function, known as SHA-0. In 2001, NIST published a draft sha-256 algorithm, which was published as an official standard in 2002.
Commonly used hash algorithms include MD5, SHA-1, SHA-256, SHA-384, and SHA-512. In blockchain, the SHA-256 algorithm is commonly used for block encryption, and for messages of any length, SHA256 produces a 256bit long hash value, called a message digest. This summary is equivalent to an array of 32 bytes in length, usually represented by a hex string of 64, which is the 64 characters we see.
