Blockchain Transaction Prioritization Research Guide

Glossary

Term DefinitionsBlockchainA distributed ledger technology that uses cryptography to link transaction records into blocks, each of which contains a hash of the previous block. BlockThe basic unit of a blockchain, containing a set of verified transactions and other data. TransactionAn exchange of value recorded on a blockchain, such as a cryptocurrency transfer or smart contract execution. Validator/MinerA node responsible for verifying transactions and adding new blocks to the blockchain. A target block refers to a specific block to which a particular transaction is desired, either the next block or the one after that. Proxy NodeA node that runs software to increase the probability of a transaction being written to a target block, which may or may not be a validator. PropagationThe process of broadcasting transaction information to a blockchain network. Network latencyThe time it takes for information to travel across the network. Transaction feeA fee that a user pays a validator to include their transaction in a block. Mining poolAn organization where multiple miners join together to increase the probability of mining. Short Answer Questions

What role do proxy nodes play in a blockchain network? Proxy nodes run specialized software designed to increase the probability of a particular transaction being written to a target block. They can achieve this by monitoring network status, optimizing transaction propagation time, and adjusting transaction fees.

Why is network latency an important factor affecting transaction priority? Because blockchain networks are distributed, transaction information takes time to propagate to all nodes. The lower the network latency, the faster the proxy node can propagate transactions to validators, thereby increasing the probability of them being written into the target block.

Explain the concept of "target block" and its relationship to transaction priority. The target block refers to the specific block to which a specific transaction is expected to be written, which can be the next block or the block after that. By predicting the generation time of the target block and choosing an appropriate propagation strategy, the proxy node can increase the probability of the transaction being written into the target block.

How does transaction fee affect the priority of transactions in the blockchain network? Validators usually prioritize transactions that pay higher transaction fees. The proxy node can analyze the network situation and dynamically adjust the transaction fee to make it stand out from the many pending transactions, thereby increasing its probability of being written into the target block.

Describe a specific technique that the proxy node uses to increase transaction priority. Proxy nodes can monitor the geographical distribution and network latency of validators in the network, and prioritize transactions to validator nodes that are closer, thereby increasing the probability that transactions are packaged first.

How do proxy nodes use historical blockchain data to optimize transaction priority? Proxy nodes can analyze historical block data, such as block generation time intervals, transaction fee distribution, etc., predict future network conditions, and adjust transaction propagation strategies and transaction fees accordingly to increase transaction priority.

What is the concept of "pre-signed transactions"? How does it relate to increasing transaction priority? Pre-signed transactions refer to pre-signed transactions that can be broadcast to the network immediately when needed. Proxy nodes can use pre-signed transactions to prepare transactions before the target block is generated and propagate them in time, thereby increasing the probability that they will be written into the target block.

Why is it important to understand the operating mechanism of mining pools to improve transaction priority? Mining pools control the computing power of the blockchain network and have a great influence on transaction packaging. Proxy nodes need to understand the packaging strategies of different mining pools, such as minimum transaction fee requirements, network propagation speed requirements, etc., in order to adjust transaction parameters more specifically and increase the probability of being written into the target block.

How do proxy nodes collaborate to improve transaction priority? Proxy nodes can share network status information with each other, such as validator distribution, network latency, transaction pool status, etc., and coordinate to adjust transaction propagation strategies and transaction fees to jointly improve transaction priority.

In addition to the technologies mentioned in the article, can you think of other ways to improve transaction priority? You can consider establishing a partnership with a mining pool to prioritize specific transactions; or use layer-2 solutions, such as the Lightning Network, to bypass main chain congestion and achieve faster and lower-cost transaction confirmation.
