          The Tritanium Traceability Blockchain is a hybrid public blockchain platform designed to host distributed applications supporting traceability use cases. The business blockchain was built from the ground up to support ingredient traceability, manufacturing, and supply chain using the principles of the original Bitcoin blockchain. The business blockchain is anchored to a public blockchain supporting the TTNZ coin based on the Cryptonote platform. Although the traceability blockchain is designed to provide traceability in the manufacturing and supply chain processes, the cryptocurrency portion of the platform provides single use keys, mixed inputs, and ring-signatures to provide the highest level of privacy for cryptocurrency transactions. Proof of Work is performed using the ASIC resistant Cryptonight Lite V7 algorithm and business blockchain data is stored using 256-bit encryption.

Background

          The original blockchain platform was presented in the white paper bitcoin.pdf by Satoshi Nakamoto in 2009. The original blockchain was designed to be a peer-to-peer cash transfer system managed using consensus with no central authority. The original blockchain introduced the concept of an immutable distributed ledger where transactions cannot be deleted or changed once they become part of the blockchain. This provides a permanent record of all transactions stored on the blockchain. The Bitcoin blockchain also introduced the concept of Proof of Work that allows the public to participate in protecting the integrity of the blockchain by solving an intensive problem for a reward. This process called “mining” is based on a security technique called “hash cash” that was introduced in 1999. Mining and proof or work have been an important part of blockchain integrity since the first blockchain was launched in 2009. Although permission blockchains do not continue the process of mining, the ecosystem mining creates is critical to the success of public blockchains.

          To be an effective cash transfer system, the platform must solve the basic problem in cash management, the “double-spend” problem. Solving the double-spend problem ensures that users of the system cannot introduce additional coins into the system or spend the same coins more than once. The Bitcoin blockchain, and all cryptocurrency blockchains since, use an algorithm called unspent transaction output (UTxO) to solve the double spend problem in a distributed environment. The UTxO algorithm also provides transparency and traceability to users of the distributed ledger.

          The blockchain defines a coin as a chain of digital signatures where the inputs to a transaction are the outputs of one or more prior transactions. This causes transactions (data) within the blockchain to be linked and provides full traceability as a byproduct. With early blockchains such as Bitcoin and Ethereum it is possible to trace the history of any coin back to the miner that originally created it. It is also possible to trace any coin forward to see each owner of the coin throughout its history.

          Although traceability is not always desired in a cryptocurrency platform, traceability is important in use cases like manufacturing, logistics and food safety. In 2016 Edward Honour began development of a private blockchain designed to promote the traceability features of blockchain to support tracking non-monetary assets using the blockchain. During the development process it became clear that traceability use-cases are better served using a public blockchain ecosystem like that provided by Ethereum. The Ethereum platform launched in 2015 introduced independent distributed applications (dApps) that run on the Ethereum platform and pay a fee, called gas, to operate.

          The Tritanium hybrid blockchain anchors the blocks created in the business blockchain to the public blockchain by hashing traceability transactions and linking them to cryptocurrency transactions. Traceability application users pay a fee to the miners for validation transactions and protecting the blockchain. Through the implementation of the first distributed applications (dApp), Food Ledger, and real world use cases, the Tritanium platform has evolved to become a way for businesses and blockchain service providers to use the blockchain for traceability.
