Currency statistics

Bitcoins in circulation
The total number of bitcoins that have already been mined; in other words, the current supply of bitcoins on the network.

Market Price (USD)
Average USD market price across major bitcoin exchanges.

Market Capitalization
The total USD value of bitcoin supply in circulation, as calculated by the daily average market price across major exchanges.

USD Exchange Trade Volume
The total USD value of trading volume on major bitcoin exchanges.

Block details

Blockchain Size
The total size of all block headers and transactions. Not including database indexes.

Average Block Size
The average block size in MB.

Orphaned Blocks
The total number of blocks mined but ultimately not attached to the main Bitcoin blockchain.

Transactions per Block
The average number of transactions per block.

Median Transaction Confirmation Time (With Fee Only)
The median time for a transaction to be accepted into a mined block and added to the public ledger (note: only includes transactions with miner fees).

Mining information

Hash Rate
The estimated number of tera hashes per second (trillions of hashes per second) the Bitcoin network is performing.

A relative measure of how difficult it is to find a new block. The difficulty is adjusted periodically as a function of how much hashing power has been deployed by the network of miners.

Mining Revenue
Total value of coinbase block rewards and transaction fees paid to miners.

Total Transaction Fees
The total value of all transaction fees paid to miners (not including the coinbase value of block rewards).

Cost % of Transaction Volume
A chart showing miners revenue as percentage of the transaction volume.

Cost per Transaction
A chart showing miners revenue divided by the number of transactions.

Network activity

Unique Addresses
The total number of unique addresses used on the Bitcoin blockchain.

Transaction Volume
The number of daily confirmed Bitcoin transactions.

Transaction Volume excluding Popular Addresses
The total number of Bitcoin transactions, excluding those involving any of the network's 100 most popular addresses. popular addresses.

Transaction Volume excluding Long Chains
The total number of Bitcoin transactions per day excluding those part of long transaction chains. There are many legitimate reasons to create long transaction chains; however, they may also be caused by coin mixing or possible attempts to manipulate transaction volume.

Total Output Value
The total value of all transaction outputs per day (includes coins returned to the sender as change).

Estimated Transaction Value
The total estimated value of transactions on the Bitcoin blockchain (does not include coins returned to sender as change).

Estimated USD Transaction Value
The Estimated Transaction Value in USD value.

Trade Volume vs Transaction Volume Ratio
Chart showing the relationship between BTC transaction volume and USD exchange volume. Discussion

Bitcoin Days Destroyed
Bitcoin Days Destroyed is a weighted measure of aggregate economic activity, placing value on transacted coins in proportion to the time they have spent idle on the Bitcoin blockchain. For any given transaction, Days Destroyed is calculated by multiplying its estimated transaction value by the number of days since the coins within the transaction were last spent. Bitcoin Days Destroyed is a useful proxy for measuring growth in real value transacted on the Bitcoin blockchain over time, since it controls for rapid movement of coins between wallets (potentially owned by just one entity).

Bitcoin Days Destroyed Cumulative
Bitcoin Days Destroyed is a measure of the transaction volume of Bitcoin. If someone has 100 BTC that they received a week ago and they spend it then 700 bitcoin days have been destroyed. If they take those 100BTC and send them to several addresses and then spend them then although the total transaction volume could be arbitrarily large the number of bitcoin days destroyed is still 700.
