? BTC Address Lookup (Master Thesis)

A solution for collecting abuse reports of Bitcoin addresses. BTCAbuseCrawler (Python) crawls and parses freely available websites and processes the data into a database (PostgreSQL). BTCAbuseSearch (JavaScript, Node.js) provides the collected data via website or API to the user based on their role in the system. Both tools can be run in parallel.

Footnotes

  1. Creates PostgreSQL users, database and its tables.
    Fills the tables with the initial data.
    Sets some performance parameters of the PostgreSQL server.
    Restarts the PostgreSQL service. ↩

  2. Deletes PostgreSQL users, database and its tables.
    Sets the default parameters of the PostgreSQL server.
    Restarts the PostgreSQL service. ↩

  3. Uses multiple threads for crawling sources which do not contain new addresses (mainly reports). ↩

  4. The program automatically checks the availability of new data.
    Once the new data are available, it downloads and stores them in the database and on the disk.
    The program never stops unless it is terminated by the user or the operating system. ↩

  5. The Crawler respects robots.txt rules of each source. ↩ ↩2

  6. The Crawler is able to find out the cryptocurrency of a given address from all of the blockchains available on Blockchair. ↩ ↩2 ↩3 ↩4 ↩5 ↩6

  7. The Crawler saves only the data that contains useful information about certain BTC address. ↩ ↩2 ↩3 ↩4

  8. The Crawler connects the crawled addresses and data. ↩

  9. If you do not open the command line as administrator, you would be prompted by the User Account Control (UAC). ↩

  10. Running the program as administrator is required because the program runs another commands (installing packages, restarting PostgreSQL, etc.) which need administrator access. ↩
