Taraxa is excited to announce the ongoing work towards integrating a timestamp oracle solution using the world’s leading decentralized oracle provider, Chainlink. This will provide the Taraxa blockchain with a decentralized and trusted source of time for all informal transactional agreements, enabling Taraxa’s smart contracts to leverage real-time (pun intended) data feeds from sources such as NIST as a means of assigning timestamps to anchored transactions in its audit log.

How Chainlink’s Decentralized Timestamp Oracles Benefit Taraxa’s Use Cases.

The Chainlink-powered decentralized timestamp oracles will verify the chain of custody for off-chain transactions and the timing of data commitments anchored into the Taraxa ledger. …

In the run-up to our yet the biggest partnership release, we’d like to revist the current state of our Ecosystem.

Why track informal transactions?

In our hyper-connected world, individuals and businesses remain vulnerable to the confusion associated with off-chain data and informal daily agreements between buyers and sellers, lenders and borrowers, clients and contractors, companies and employees. At the same time, even with today’s abundance of messengers and collaboration suites, there’s still no handy way to keep track of those offline deals that are made every day through talking, calling, and texting — from trivial pay-upon receipt services and parenthood or property relations to auto repairs, employment relations, or simply signing off on an invoice. …

We’re starting a new series to spotlight our brilliant team members! This week, we welcome Leo who’s been working for Consensys prior to joining Taraxa’s distributed team.

Talk about what you do in your role?

I’m an Ecosystem Engineer working on all public-facing parts of the project as well as various integrations with other platforms and clients. This role is perfect for me because I have experience both in developing Solidity smart contracts and building web apps.

UniCask is a joint venture formed by Japan Import Systems, one of the largest spirits trading companies in Japan, announced today that they’ve signed a commercial collaboration with Taraxa to help build confidence in their spirits ownership tracking solution, scheduled to launch in spring of 2021.

UniCask was founded to make tracking rare and collectible spirits simple and secure, enabled by blockchain technology. Since the actual spirits are remotely stored in professional facilities, Unicask wanted to ensure that owners have the highest confidence in the location and status of their assets. …
