What is Chainwatch?
Chainwatch is real-time blockchain network monitoring utility. Through chain reorganization detection and network statistics analysis, Chainwatch analyzes blockchain networks for attempted 51% attacks. Check out the Chainwatch Dashboard (source code here) at http://chainwatch.info. Read the Chainwatch research paper here.
- Detecting chain reorganization events: Chainwatch maintains a sliding window to detect when forks are merged.
- Analyzing network statistics: Chainwatch collects high-resolution data on network statistics (i.e. hashrate, blocktime, difficulty).
- Tracking miner hashrate share: Chainwatch tracks the estimated hashrate of each miner over time, flagging miners that gain a majority hashrate.
