The Factoid Authority Explorer enables users of the Factom Protocol to explore the Factom blockchain without the need of running your own node. This is for all users and developers of the Factom protocol to validate their entry and factoid related transactions against. The TFA explorer provides more data than a normal node, such as providing all the entries an EC address has paid for.
Check out the site to view the various data related pages and realtime heartbeat monitoring. The explorer exists for both main-net and test-net, ensuring the whole Factom ecosystem is covered.
