The powcoin algorithm: Why is it not as efficient as you think
For more than a decade, the world’s largest cryptocurrency protocol in the world, Bitcoin, has been based on the Work Testalgorithm (POW) to ensure its decentralized network. This algorithm was widespread due to its high security and decentralization of other cryptocurrencies and blockchain networks. However, many critics have for a long time argued that this approach is inefficient and can lead to a block distribution that promotes large miners at the expense of small scale users.
In this article we will examine why the Bitcoin Pow -Algorithm does not use Hashes chain with low differentiation and examines alternative approaches that could improve their efficiency.
The current pow algorithm
The Bitcoin Pow Algorithm is based on the Hash SHA-256 function, which is mathematically intense. Each block in the block chain contains a clear digital signature with the recipient’s public key. In order to validate transactions and create new blocks, miners have to solve complex mathematical puzzles using hash functions.
This is how it works:
- The miners compete for a solution for the following equation:
2^256 * 13^83 % 2^64 = 0
However, X is the block number and it is the target hash value.
- The miner, who finds the solution first, can add a new block to the block chain and transfer it to the network.
- The miners check that the new block contains applicable transactions if they check whether the sender’s public key was used at least once.
The problem with the current Pow algorithm
The current Pow algorithm suffers from several problems:
* Block time distribution : As already mentioned, the current Pow algorithm leads to a very unbalanced block distribution. Large miners dominate the network while small users often fall back.
!
* Energy consumption : Bitcoin Minero requires considerable amounts of energy, which can be a big environmental problem.
The alternative: Hash -Base -Algorithm
In order to address these problems, some researchers have proposed alternative algorithms that use hashes with a lower influence. Here is a general description:
* Hash -based algorithm : Instead of using complex mathematical puzzles to create new blocks, this approach is based on the hash function itself. The idea is to reduce the difficulty of finding a solution by the size or number the entries in the hash function is increased.
* Modular hash functions : Modular hash functions such as SHA-256 With a larger input variable (e.g. 512 bits instead of 256), it can be designed so that smaller output hashes are generated with greater safety.
Advantages of the Hash -Base -Algorithm
The hash base -algorithm can have several advantages:
* improved efficiency : By reducing the calculation requirements for mining, hash -based algorithms can increase the number of blocks that can fit into a certain time frame.
* Reduced energy consumption
: If energy prices rise, hash -based algorithms can help reduce energy consumption by increasing the block production rates.
* increased decentralization : Hash -based algorithms can promote decentralization by reducing the influence of large miners in the network.
Examples and implementations
Several cryptocurrencies have implemented Hash -based algorithms, including:
* Serenity : A screenpotomone from Tobacconist (POS), which uses a modular hash function to create new blocks.
* Fragment : An upcoming cryptocurrency that uses a hash -based algorithm to produce new blocks.
* Masternode : A decentralized network of nodes that validate transactions using a hash -based protocol.
