Collecting Information on a Blockchain

Data Available on the Blockchain

The price of Bitcoin is only a single gauge of the level of activity in the Bitcoin Network. At the peak of Bitcoin’s price in December of 2013, transactions peaked at an all time high of 102,000 with an average of 60,000 transactions. Today, with the price of Bitcoin below a quarter of peak value, 100,000 transactions are average. Connecting information to the level of activity in the Bitcoin Network will require further analytic data. The next resource a Bitcoin market researcher could pursue is a Blockchain Explorer.

Blockchain Explorers

Information gathering tools for blockchain inputs offer specific data that is only useable for specific use cases. There are two levels of API’s available for developers to design software applications. REST API and Webhooks API SDK. The difference between these tools is how the data is recalled. Webhooks can be created to send a notification of a specific event, such as the creation of a new block. Highlighted below are a few explorative services and data sets that can be collected from various interfaces:


Biteasy has the longest reputation of block explorers on this list. Biteasy updated to version 2.0 in March with more features for developers to create applications with Biteasy’s REST API. A new feature of Biteasy is independent Input and Output values end-points that can be isolated individually.

Biteasy Endpoints:
  • Address Information
    • Multiple or single addresses
  • Block Specifics
    • Block Hashes
  • Transaction Data
    • Transaction Hashes
  • Data Inputs
    • Input Hashes
  • Data Outputs
    • Output Hashes
  • Multisig Verification
    • # of multi signatures reached
  • Search Functionality


Blocktrail is a Blockchain Explorer firm offering explorer services leaning towards economic data sets. These data sets are more specific financial information and are preferred for tracking market activity or market prediction. The Blocktrail API has the ability to recall that data to user chosen platforms for further analysis.


Blocktrail Endpoints:

  • Address
    • Address Confirmed/Unconfirmed Transactions
    • Address Unspent Outputs
  • Blocks
