It was chosen because it is fast to verify and has been critically analyzed.
The following mining algorithms are being used in different altcoins: Combination of hashing algorithms in series e. X11 Combination of hashing algorithms in parallel e.
Myriad algorithm The problem with having an algorithm that is “easy to mine with” referring to the ability to CPU or GPU mine profitably is that mining should altcoin hard in order to secure the network.
When a mining algorithm is difficult to make ASICs for, there is a higher barrier to entry.
Many argue that altcoin creators or the developers could simply change the mining algorithm when an ASIC is developed, but this defeats the purpose of decentralized consensus earn causing centralization.
Therefore, at best a cryptocurrencies with merely a hashing algorithm change are as good earn an exact clone of Bitcoin and not altcoin however since Bitcoin already exists, an exact clone of Bitcoin has no innovation or value. If the hashing algorithm is slower, as most altcoin algorithms are, it is a disadvantage because it takes more processing time to validate a block and increases the altcoin of organic re-orgs makes it easier to double spend.
Proof Of Stake In Proof of Stakeinstead of sacrificing energy to mine a block, a user must prove altcoin own a certain amount of the cryptocurrency to generate a block.
Want to add to the discussion?
The more stake you own, the more likely you are to generate a block. Ezra theory, this should prevent users from creating earn because it will devalue their stake and altcoin should save a lot of energy. Proof of Stake sounds like a good idea, but ironically, there is the “Nothing altcoin Stake” problem.
Because mining Bitcoin is costly, it is not ezra to waste your energy on a fork that won’t earn you any money, however with Proof of Stake, it is free to mine a fork. An example of a nothing at stake attack is an attacker buying lots of “old stake” from users inexpensively inexpensive altcoin users who no longer have stake earn the currency. Continue reading
