TRAC (Ordinals) is a significant infrastructure project within the Ordinals ecosystem. It aims to provide a decentralized system for tracking and accessing protocols related to Ordinals, such as BRC20 tokens and sats domain names. This decentralized system is designed to incentivize the security of the tracking network and allows for voting on new and updated protocols, as well as overall governance within the ecosystem​​.

The TRAC token, which is a BRC-20 token on the Bitcoin blockchain, was inscribed on May 3, 2023. It has a total supply of 21 million tokens with a limit of 1,000 tokens per mint​​. Trac is committed to enabling decentralized tracking of Ordinals metaprotocols, addressing the issue of centralized trackers which contradict the decentralized ethos of cryptocurrencies like Bitcoin. By providing a decentralized network, Trac enables anyone to connect, utilize, and earn from it​​.

One of Trac's key features is Trac Core, a cutting-edge tool that integrates with the blockchain to manage Bitcoin's extensive data. Trac Core fetches updates, organizes them methodically, and makes them available for analysis and searches via APIs. With continuous synchronization with the blockchain, TRAC ensures that users have the most up-to-date information​​.

In addition to its core functions, Trac Systems, the developer of Trac, specializes in blockchain technology and has created innovative products like Trac Core, Tap Protocol, and Pipe​​. The Tap Protocol, in particular, offers secure and accessible development on Bitcoin, with unprecedented flexibility in programmability and decentralization, distinguishing it from its competitors​​. This protocol enables functionalities like fractionalizing Ordinals art, token swaps through liquidity pools, and financial services like borrowing, lending, and staking​​​​​​.
