TRAC and TAP Protocol Unlock New Capabilities on Bitcoin Layer One
TRAC (Tokenized Real Assets Coin) is a BRC20 token and one of the earliest project-based tokens on the Bitcoin blockchain. Unlike the flood of meme coins and speculative tokens that have historically dominated Bitcoin-based assets, TRAC has utility: indexing the Bitcoin blockchain. This allows developers to build applications on top of Bitcoin using the TAP protocol.
TRAC indexes the Bitcoin blockchain through a process where validators continuously collect and organize data such as transaction outputs, block heights, and token transfers. This data is then categorized into an index that developers can access for retrieval of blockchain information, such as transaction histories or token balances. A network of validators cross-checks the data to ensure accuracy before it is finalized, ensuring that developers have real-time access to reliable data.
To ensure the integrity and honesty of validators, TRAC employs several mechanisms. The decentralized validator network prevents any single entity from controlling the indexing process. Validators use consensus mechanisms, such as Proof of Stake (PoS), staking TRAC tokens to ensure honesty, as inaccurate submissions can result in the loss of their stake. Cryptographic verification ensures data cannot be tampered with, while validators are rewarded for accurate data indexing and penalized for dishonesty.
The process is transparent, allowing public auditing, and multiple validators work on the same data to provide redundancy and cross-validation. Validators can also be audited periodically to ensure data integrity, with penalties imposed on those acting dishonestly.
In essence, TRAC becomes a data layer for the TAP protocol to use.
The TAP Protocol: Bitcoin’s Meta-Protocol
The TAP protocol is a meta-protocol built directly on top of Bitcoin’s layer one (L1). Its goal is to enable secure and accessible decentralized application development without sacrificing the security and robustness that Bitcoin is known for. TAP is designed to offer tools for developers to build creation of decentralized applications (dapps) and decentralized finance (defi) protocols.
The TAP protocol leverages the decentralized indexing capabilities of TRAC to enable the platforms directly on Bitcoin. TAP needs reliable, organized data to function effectively—such as outputs, token transfers, and block heights. For example, in a decentralized finance platform built on TAP, data such as user balances, transaction histories, or token transfers must be accurately reflected in real-time. TRAC’s indexing ensures that this data can be retrieved efficiently without relying on any central authority.
The TAP protocol, as outlined in the whitepaper, uses Ordinals in such a way as to operate on the Bitcoin layer one (L1) without the need for layer two (L2) solutions. TAP extends the functionality of Ordinals and introduces a token standard that mimics, yet expands upon, the BRC-20 token structure. The Tap protocol breaks functionality into two parts: external and internal functions. External and internal functions serve different roles in interacting with tokens, wallets, and the broader ecosystem.
External functions in the TAP protocol are designed to interact with existing infrastructure, such as wallets and marketplaces, enabling the use and trading of TAP tokens in a manner similar to other token standards like BRC-20. These functions ensure compatibility with current tools and platforms without requiring extensive modifications.
Basically, they allow users and platforms to engage with TAP tokens in the same way they would with BRC-20 tokens, while accommodating TAP’s unique features. For instance, a marketplace that supports BRC-20 tokens can adapt to TAP by cloning its infrastructure and making minor adjustments to recognize specific TAP operations such as token deployment, minting, and transferring.
The core external functions include token deployment (creating new TAP tokens), token minting (creating additional tokens), and token transfer (moving tokens between users). These functions are designed for public platforms, ensuring that TAP tokens can be seamlessly integrated into defi platforms, wallets, or exchanges with minimal changes to existing systems.
Internal functions in the TAP protocol introduce advanced capabilities beyond standard token trading or minting, adding extended features and more sophisticated operations specific to TAP. Examples include token staking, token swaps, enabling direct swapping within the protocol; mass-token transfers, allowing tokens to be sent to multiple recipients in one transaction; and a more complex token-trade mechanism that includes features like fees and trade expiration.
Writers and indexers are the two main actors of the TAP protocol. Writers can be thought of as developers or users, doing tasks like token transfers. Indexers are like validators, tracking and verifying inscriptions on the blockchain.
The actions of writers are started and executed through an inscription-based verification system that ensures the process is transparent, secure, and follows the rules of the protocol. Here’s how writers start and execute an action:
Initiating the Action: When a writer wants to perform an action, such as transferring tokens or executing a trade, they submit a request to the TAP protocol. This request contains all the necessary details for the action, including the assets involved, the recipient (if applicable), and any other relevant information. The writer’s request triggers the creation of an inscription, which is a piece of data that is written directly to the Bitcoin L1 blockchain.
Inscription Creation: Once the request is initiated, an inscription is generated on the Bitcoin blockchain. This inscription acts as a verifiable record of the action, permanently storing information such as the sender’s balance, the action being performed (e.g., transfer or trade), and the outcome. Inscriptions are immutable, meaning they cannot be altered once they are written on the blockchain, providing a transparent and secure way to record actions.
Verification by Indexers: After the inscription is created, it is verified by indexers within the TAP protocol. Indexers are responsible for ensuring that the inscription follows the protocol’s rules and that the action is valid. For instance, if a writer initiates a token transfer, the indexers will check that the writer has enough balance to complete the transfer and that all other conditions are met (such as proper signatures and transaction details). Indexers cross-check the inscription with the data on the blockchain to ensure accuracy.
Execution of the Action: Once the inscription is validated by the indexers, the action is executed. In the case of a token transfer, for example, the tokens are moved from the sender’s wallet to the recipient’s wallet. The inscription on the Bitcoin blockchain acts as the proof of the transaction, and anyone can verify that the action was carried out correctly by checking the publicly available inscription.
Transparency and Accountability: Because every action initiated by a writer is recorded on-chain through the inscription-based verification system, the entire process is transparent and auditable by any participant. If there is any inconsistency or manipulation, it can be easily detected by cross-referencing the inscriptions against the Bitcoin blockchain.
Indexers act as the backbone of the protocol, providing accurate, up-to-date information on token balances, transactions, and other critical operations. Their primary responsibility is to process, verify, and maintain accurate records of inscriptions made by writers. These inscriptions are recorded on Bitcoin’s L1 blockchain, and it is the job of indexers to track and verify them to ensure seamless interaction with wallets, marketplaces, and other TAP-integrated services.
Indexers perform several key functions to maintain the integrity of the TAP protocol. They track and verify inscriptions to ensure that operations such as token minting, transfers, and trades are conducted in compliance with the protocol’s rules. This involves verifying the validity of balances, signatures, and other necessary data. Additionally, indexers are responsible for managing token balances, ensuring that transactions are recorded correctly and displayed accurately for users.
In addition to their technical responsibilities, indexers must also adhere to protocol updates and transitions. TAP provides a well-structured framework for updates, offering indexers grace periods to adjust their systems to new changes. This conservative approach ensures that all indexers have adequate time to implement necessary adjustments and continue their operations without interruptions. Indexers must follow these updates closely, as failing to do so could result in invalid operations or inconsistencies in their indexing processes.
While the TAP protocol doesn’t implement a direct mechanism to penalize dishonest indexers, it relies on several indirect safeguards to ensure accountability and integrity. Operating on the transparent Bitcoin L1 blockchain, the protocol ensures that all transactions and updates are public, making discrepancies easily detectable. Governance is community-driven via $TRAC tokens, allowing participants to address dishonest behavior through voting. Indexers must adhere to strict protocol rules for tracking and verifying transactions, with protocol updates ensuring compliance.
Lastly, the inscription-based verification system provides a natural layer of accountability for indexers. Each action within the TAP protocol—whether a transfer, trade, or token deployment—must be inscribed on the Bitcoin blockchain. These inscriptions are publicly accessible and must meet specific criteria, such as valid signatures and correct balances, to be considered valid. Any indexer that fails to follow these procedures or attempts to manipulate the data would be caught when users or other indexers review the on-chain information.
