Factoshi is a Factom Protocol Authority Node Operator (ANO) that is part of the coalition of companies that provide infrastructure to decentralise the protocol.
We created Factoshi.io which provides a host of metrics for the Factom ecosystem. Factoshi is a team consisting of two business partners with technical and crypto backgrounds.
We have published a script to enable people dealing with FCT to account for revenue in a fiat currency of their choice. The script is designed to be kept running, but it will also backfill historical transactions with historical market prices (price data for transactions which are greater than one week old are slightly less accurate). Find this script on the Factoshi Github: https://github.com/Factoshi/factoid-address-monitord
