** Ethereum: How the mining consensus works
In Ethereum, extraction is a process of transactions validation and adding them to blockchain. To ensure the integrity and security of the network, the consensus algorithm must be introduced to verify these transactions without any node or computer controlling the whole process. One of the key challenges in achieving this consensus is the use of a shortcut function that are used to create a unique digital fingerprint for each transaction block.
How does the Ethereum consensus work?
In Ethereum, the consensus algorithm used is called proof of work (Jed). This means that miners compete for a solution to a complex mathematical puzzle, which requires considerable computing power. The first miner who solves the puzzle can confirm transactions and create a new block. The new block is added to blockchain, which is then broadcast to all other nodes on the web.
How does mining consensus prevent seeds from duplicating?
The main problem in achieving a consensus without a single knot or computer controlling the whole process is how miners ensure that the seeds (or shortcuts) for each block of transactions are not the same. Here’s how:
- Shortcut functions : Each block has a unique abbreviation function that is used to create a digital fingerprint of the block. The shortcut function adopts the contents of the block as an input and sends a constant size string, known as a «block shortcut».
- Generation of seeds : To generate grain, miners use many random numbers (known as «nonce») and combine them with the shortcut. This process is repeated many times until unique seeds generated.
- Blocking the abbreviation and seeds : When creating a new block, Górnik connects the contents of the block (including the abbreviation of the previous block) with previously generated seeds. The resulting combination is known as a «block shortcut».
- Proof of work : To create a block shortcut, miners must solve a complex mathematical puzzle. This puzzle requires considerable computing power and is intended for use by malicious actors.
- Difficulties in regulation : When more miners join the network, the level of difficulty in solving the puzzle increases. The difficulty mechanism in regulation ensures that the puzzle remains difficult, but not impossible to solve.
How do mining customers provide unique seeds?
To make sure that unique seeds are generated on each mining set, mining customers use a combination of techniques:
1.
2.
- A shortcut function : The resulting grain is then judged using the cryptographic abbreviation function (such as SHA-256 or Ecds) to ensure its uniqueness.
additional funds
To additionally prevent duplication of seeds, Ethereum has implemented additional funds:
- Mining Pulling : Miners combine their resources to increase the likelihood of finding a unique solution to the puzzle.
- Time to block time and difficulties : The block time (time needed to solve the puzzle) is increased when more miners connect to the network, which hinders the use of the system using brutal force.
- Energy requirements
: Energy requirements for solving the puzzle are high, which reduces the encouragement for malicious actors to try the system.
Application
In summary, the Ethereum consensus algorithm, proof of work (POW), requires from miners to use complex mathematical puzzles to validate transactions and create new blocks. To prevent duplication of seeds, mining customers use a combination of a random number function, mixing seeds and shortcuts to ensure uniqueness.
