On-chain data from public blockchains serves as a crucial indicator for evaluating blockchain project value. This data encompasses multiple dimensions including active addresses, new addresses, on-chain transaction volume, average transaction size, block size, block time, mining difficulty, average transaction fees, and average gas prices. By analyzing these on-chain metrics, users can gain deep insights into a public chain's technical capabilities, economic model design, ecosystem activity levels, and development momentum, enabling more accurate assessments of specific blockchain networks' long-term value.
Blockchain explorers are essential tools for accessing on-chain data, serving as visualization windows that record and compile detailed information about every block, transaction, and address across different public chains. OKLink, developed by the world's first publicly listed blockchain big data company, is a blockchain information service platform that leverages blockchain and big data technologies to provide highly reliable blockchain information services. The platform integrates multiple query and service functions including blockchain explorer, on-chain monitoring tools, and advanced analytics features.
The OKLink homepage displays four core fundamental data points for various mainnet blockchains:
Latest Height: Refers to the height of the most recently packaged block, essentially the block's number. Block height represents the number of blocks between the latest block and the genesis block (the first block on a blockchain, with height 0). Blockchain is fundamentally a ledger system that packages all transactions into blocks at regular intervals, with block height indicating which block has been generated in sequence.
Last Block Time: Reflects the elapsed time since the current latest block was generated, helping users understand block generation timeliness.
Circulating Supply: Indicates the actual quantity of tokens circulating in the market, serving as a vital indicator for assessing project market capitalization and liquidity.
Unconfirmed Transactions: Represents the number of transactions awaiting miner confirmation. When this number is large, it indicates significant transaction backlog, typically accompanied by rising average transaction fees due to network congestion.
Through the OKLink platform, users can quickly search and query specific addresses, individual transactions, and block heights, with support for detailed on-chain data queries across 11 major public chains including Bitcoin, Ethereum, and Polkadot.
Using Bitcoin as an example, OKLink provides multiple key metrics to help users comprehensively understand network status:
Hash Rate Analysis: Hash rate represents how many computational attempts a mining machine can execute per second, measured in Hash/s. Network hash rate is the total computational power of all mining machines participating in the network. Bitcoin's network hash rate is measured in EH/s (exahashes per second). The network hash rate of a digital asset reflects mining activity levels for that asset—larger hash rates and faster growth indicate greater miner confidence in the asset's prospects. Currently, Bitcoin maintains the largest network hash rate among all cryptocurrencies.
Network Difficulty: Bitcoin's network difficulty, or mining difficulty, represents the accumulated computational capacity of the blockchain network. It determines how difficult it is for miners to find the correct hash signature for a block during hash calculations and the time required. Bitcoin mining difficulty automatically adjusts every two weeks based on production efficiency. When more miners join the network, total hash computational power increases, allowing miners to find correct signatures and add blocks more quickly. However, to maintain the stable pace of generating one block every 10 minutes, the network automatically triggers an increase in mining difficulty. Therefore, the higher the accumulated hash rate, the higher the block difficulty.
Mining Profitability Assessment: Calculating mining profitability can reference three indicators: "per-unit hash rate revenue," "current optimal transaction fee," and "24-hour average block reward." The current optimal transaction fee is calculated in real-time based on average transaction fees from recent blocks and transactions in the pending confirmation pool. The sum of these three indicators provides insight into potential mining profitability levels.
Network Congestion Monitoring: "TPS," "median block size," "average block time," and "unconfirmed transactions" collectively reflect network congestion status. TPS (Transactions Per Second) indicates the number of transactions processed per second, reflecting the blockchain network's transaction speed. Currently, Bitcoin's TPS is approximately 3, meaning it can process about 3 transactions per second. Median block size reflects the number of transactions the network can accommodate, directly related to memory capacity. Average block time is the dynamic result of network difficulty coefficient and total hash rate working together.
