The impact of node data status on mining
The operation of blockchain network nodes requires backtracking verification of sufficient blocks and transaction history data to effectively ensure the probability of the excavated blocks being accepted by other nodes. Node data synchronization usually occurs when a node first connects to a blockchain network, or when it is offline for a period of time before reconnecting. The time required for synchronization is related to the integrity of local block data, network communication efficiency, local resource utilization status, and the latest block information received. To enter the mining state as soon as possible and maintain the efficiency of mining blocks as a whole node, it is necessary to equip the node with an independent public IP, stable and good network connection, and have hardware conditions such as multi-core CPU and large memory, independent graphics card, and large capacity disk storage.
Prior to mining, the entire Paralism node needs to fully obtain all historical block data and complete integer verification. This process usually takes several days. As the accumulated block data increases, the longer the offline time of the node, the longer it will take to reconnect for data synchronization.
View data status
During data synchronization or mining, you can enter the rs paracoin command at the terminal hc $prompt to view the data status of the default base currency Para.
As shown in the above figure, the current coin name indicates that the current Paracoin “a33a70884e516eee7fb41d8ffa38d5ddee3cd2ac121cd46a853cd29bb13c4e53” is the founding block hash of the current mining Cryptocurrency.
Model is PARA
Neighbor node displays the number and list of public network and local area network neighbor nodes discovered by the node.
Genesis Block Address: 203238 1 1 identifies the triple address of the starting block of the Cryptocurrency blockchain when it is created in the parallel blockchain.
Mining Status: Stopped indicates that the node is not mining.
Data synchronization
Synchronization preparation stage
During the data synchronization process, enter the rs command and pay attention to the information provided by the Mining status. At the beginning of data synchronization, a prompt “Stopped, My latest super…” will be displayed, indicating the start of connecting to the network. Whenever this information is displayed when a node connects to the network, it indicates that the node needs to obtain the latest block data from other network nodes.
Data backtracking stage
During the node data synchronization process, the Mining Status displays “stopped, the chain is incomplete,… 170095… backtracking block: 169350…”, indicating that the node has synchronized some block data and is backtracking and verifying the block data. Last block height is the latest block height and corresponding superblock number of the Paracoin blockchain obtained by the node’s listening, and backtracking block is the block number that the node has backtracked and verified.
The time required for data synchronization is related to the network connection status of the node, the accumulated amount of blockchain data when the mining machine joins the network, and time. As the block height of the Paracoin blockchain continues to increase, the synchronization time will correspondingly increase, ranging from a few days to a few weeks.
Data organization stage
After a period of synchronization, if the Mining status displays “Switching to the best chain” when the rs command is input, it indicates that the node has completed the synchronization of the blockchain data and is currently verifying and organizing the blockchain data blocks. The longest chain that the node should follow is calculated to eliminate the risk of mining blocks being rejected by other nodes.
Data synchronization completed
If the Mining status displays “mining” when entering the rs command, it means that the node has completed the verification and organization of the blockchain and started the mining process.
Operation and maintenance of mining
During the mining process, it is necessary to pay attention to the utilization of host resources, network status, and mining progress. If necessary, optimize the host configuration and network to improve mining efficiency.
In the network state, the number of neighboring nodes is an important indicator of the node’s network connectivity. In a distributed network, the number of neighboring nodes indicates the node’s ability to communicate with other nodes. The stronger the communication ability, the faster and more mining blocks can reach other nodes, and the probability of legal blocks being accepted by the entire network will greatly increase.
The node command can be used to query the neighbor nodes of this node. The Syntactic sugar is n for short. The command will return the public network node that the node successfully connected to and the node in the same network segment as the local area network where the node is located. An example of the returned results is as follows.
After the node mining starts, you can use the command resolve <Application Name> to query the running status of the application at any time. The Syntactic sugar is abbreviated as rs, for example, rs paracoin queries the status of paracoin mining process, and Mining Status is mining, indicating that the program is running normally.
A Mining Status of stopped indicates that the mining process is paused. You can further check the reason for the pause. As shown in the red box, the reason for the pause is that there are over 40 excavated blocks in this node that have not yet received confirmation from other nodes. This situation is usually caused by communication barriers between this node and other nodes, leading to a soft fork in the blockchain. Generally, after eliminating network communication issues, restart the mining process using the coin e command, and the node will automatically synchronize the latest network block data to handle the soft fork problem, After completion, the mining and block extraction will continue.
