Algorithm to select coins on Ethereum: Deep diving
As for the transactions on the Ethereum network, the choice of the right combination of inexhaustible outputs (USOS) is crucial. This process, known as an algorithm to select coins or costs, determines which undeniable inputs will be used to pay a transaction. In this article, we will study how the algorithm for selecting Ethereum coins works and whether it has changed over time.
The standard customer
In the standard customer, transactions are created using the Ethereum virtual machine (EVM). When creating a transaction, the user selects one or more inexpressant exits from the balance sheets of his account as inputs. EVM then uses this information to determine which USOS will be used to select coins.
Coins Selection Algorithm
The coin selection algorithm is based on the concept of “generation of coins” and “costs”. According to Whitepaper Ethereum, the algorithm works from:
- Identification of non -consumer outputs from the user’s account balance.
- Use of these inputs to determine which coins will be used for costs (ie payment of transactions).
- Assignment of coin priorities on the basis of their available supply and difficulty of yield.
In other words, the algorithm first chooses the most short and difficult to wash coins, ensuring that they have a great chance of being consumed in large quantities.
Changes History
Interestingly, the algorithm for choosing Ethereum coins has undergone changes from its original version. The 2015 version was based on a simple linear sorting algorithm, where all undeniable outputs were sorted by their availability and then first assigned to the most sloping coins. This approach had some restrictions, such as allowing extremely low priority coins.
In Response to These Criticisms, Ethereum Developers Introduced the Current Coin Selection Algorithm in June 2016. To Account Factors Like The Coin’s Available Supply and difficulty in mining.
Current Algorithm to Choose Coins
The current coin selection algorithm is as follows:
- Sort all indisputable exits on their availability.
- Assignment of cost priority (SP) at each outcome based on its availability and difficulty of yield.
- Sort the sorted list based on SP values, with more expensive coins getting higher priorities.
Conclusion
The Ethereum coin selection algorithm is a complex mechanism that guarantees the fairness and efficiency of transactions on the network. Using a combination of sorting and prioritization, the algorithm first chooses the most scarce and difficult to wash coins, reducing the likelihood of high-priority coins consumed in low quantities.
While some critics have expressed concerns about the simplicity of the algorithm, Ethereum developers claim that this approach provides a good balance between justice and computing efficiency. As the Ethereum network continues to develop, it will be interesting to see how future updates improve and improve this algorithm to choose coins.
