Charts Page: /charts or /charts/{chart name}

When the charts is based on time series, they are generally based on daily statistics, which mean the If not explictly specify the time series unit of the chart, it means the charts is generated as daily statistics.

  • Block
    • Block time distribution: the x-axis is block intervals in seconds, and the y-axis is the frequency of occurrence in the latest 50,000 blocks.
    • Epoch time distribution: the x-axis is epoch intervals in hours, and the y-axis is the frequency of occurrence in the latest 500 epochs.
    • Average block time: average block intervals with daily & weekly sliding smooth window First calculate average block time by hour, and then calculate average daily smooth window by each timestamp with its preceding 24 hour records. Calculate rolling average weekly by each timestamp with its preceding 7 * 24 hour recrods. The x-axis of this chart is based on hour.
  • Mining
    • Difficulty & Hash Rate & Uncle Rate
    • Epoch Time & Epoch Length
    • Difficulty
    • Hash Rate
    • Uncle Rate
    • Top Miners(Recent 7 days)
  • Activities
    • Transaction count per day
    • Unique address Used per day: count of addresses used accrued from 0
    • Cell count: current total count of live cells and dead cells on chain by each day.
    • Balance ranking: list 50 addresses that hold the most capacity
    • Balance distribution
    • Transaction fee
  • Nervos DAO
    • Total deposit: total deposited and locked capacity on chain and deposited addresses by each day.
    • Daily deposit: deposited capacity and deposited addresses per day
    • Deposit to circulation ratio: the ratio of DAO deposit to circulating supply. Where the circulating supply is equal to the total supply minus the burnt part and the unvested part.
  • Economic Status
    • Total supply: Total supply equals the sum of the primary issuance and the secondary issuance; The burnt part equals the sum of the 25% genesis issuance burnt and the burnt portion in the secondary issuance; The unvested part equals the portion that is locked by time lock, which will be released gradually by a predefined schedule. The circulating supply is equal to the total supply minus the burnt part and the unvested part.
    • Nominal DAO compensation rate: The nominal compensation rate is provided by DAO when there is no burnt portion in the secondary issuance. The real compensation rate is always higher than the nominal compensation rate.
    • Secondary issuance: The secondary issuance is automatically divided into three parts, the compensation, the mining reward, and the treasury (burnt by now). They are proportional to the DAO deposit, the storage occupation, and the rest of CKBytes.
    • Inflation rate: Nominal inflation rate: the inflation introduced by the primary issuance and the secondary issuance. Nominal APC: the anti-dilution compensation rate of Nervos DAO. Real inflation rate: the compound inflation rate the nominal inflation rate minus the nominal APC, which is gradual to zero.
    • Circulating Supply Until specific block, the total issued CKBytes minus all kinds of locked CBbytes and burnt amount.
    • Liquidity Circulating Supply minus current DAO total deposits.
