Providing maximum transparency for AccuGroup’s customers, who are the top automotive OEMs in the world

For almost 20 years, AccuGroup has provided unparalleled quality solutions including consulting, inspections, and certifications to some of the world’s largest brand names such as BMW, Volkswagen, and Samsung. As the industry evolves, these supply chain ecosystems have become increasingly more complex, and AccuGroup’s team comes into contact with an ever-more complex set of stakeholders. …

As we continue to refine Taraxa’s testnet, we’ve always strived to update the community on our progress, which has not always been easy since they’re largely invisible code updates.

So instead of giving out dry and largely incomprehensible & disconnected technical jargon, we’re going to try and communicate some of the more interesting issues and solutions we’re working on in as plain English as we can make it. Let us know what you think!

Issue 1: PBFT votes

During our PBFT finalization rounds, where we finalize the Block DAG and linearize all the transactions within a finalized section (Period) of…

>80% of Transactional Data is Wasted.

People and devices generate transactional data constantly, but >80% of that is informal and goes wasted. They’re not recorded in legal documents, structured systems, and are not verifiable.

Today, we are wasting almost all informal transactional data.

Being able to access and trust informal transactional data is what drives rapid innovation and growth. Smaller organizations and projects can leverage it because they witness the data first-hand. As organizations or projects scale, they are unable to trust this data because most stakeholders do not witness it directly and therefore do not trust it. Making decisions without data usually leads down a path of downfall.

Taraxa Democratizes Reputation by Tracking Informal Transactions.

Since the English version of the book, “Blockchain and Crypto Currency” (it’s free to download!) has become available on major ecommerce platforms such as Amazon and Taobo, where I have co-written two chapters, we have received a large number of inquiries regarding the origins of the book. It’s actually a pretty interesting story, so I decided to do a quick lookback.

“METI is interested in blockchain”

Soon after Taraxa was founded in 2018, one of our earliest angel investors, Mr. Mamoru Taniya, informed us that Japan’s Ministry of Economics, Trade and Industry is interested in learning more about blockchain…

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. …

Hi everyone! We’ve been hosting lots of AMA sessions around the world and we’re amazed at your thoughtful input and excitement about our project. So I thought we’d compile all your burning questions and our answers about Taraxa in one place. This will be a weekly recurring blog series, so please shoot your questions in comments!

Q1: What has the team been up to following the sale?

While the team has been carrying on our usual development work on our infrastructure and applications, the Taraxa Foundation has been focused on making sure our investors get liquidity as quickly as possible. That’s why we immediately negotiated the listings on three crypto exchanges…

For the most recent information, please check our Public Sale Site.

Disclaimer: The offer and sale of the Tokens is not being made within the United States or to any U.S. persons (as defined under U.S. federal securities laws). You will be required to provide documentation and verify your eligibility in order to participate.

Why conduct a public sale?

After initial investments in 2018 led by Fenbushi Capital, the Taraxa Foundation has successfully launched a stable test network and multiple market-tested application platforms on top. In preparation for our mainnet launch, we want to use the public sale to kick off token distribution into the community.

As the world gears up for the new year, we’d like to take a moment to look back on our accomplishments and into the future.

A year like no other, 2020 still was a very exciting year for Taraxa. Together with you, builders, partners, and creators, we’ve hit the key milestones in both engineering and market validation, giving us the technical infrastructure and market confidence to build out our sustainable long term vision. Buckle up, as we dig into what we achieved together this past year!

Stable Taraxa Test Network Deployed.


In one of our previous articles, we defined how our Block DAG is structured and ordered, but we also raised the question that ordering can still shift over time. In this article, we present Taraxa’s method of introducing true finality into Block DAG ordering and all the associated consequences.

Importance of Finality

Most blockchain topologies today have probabilistic finality, in that you are never 100% sure whether or not the transactions are truly set in stone. For example, in BTC, you get an exponential falloff in the probability that an attacker will be able to catch up to the rest of the network…


In the previous article we explored the ordering challenge. In this article, we will explore how Taraxa achieves fair and efficient block proposals without the use of Proof of Work (PoW).

The Elegance of PoW

PoW is a simple and elegant consensus algorithm. Every node solves a simple cryptographic puzzle, whose solution is arrived at by making rapid guesses, and whoever guessed the right answer first is chosen to produce the next block on the network.

That’s it.

This simple algorithm simultaneously provides true randomness which makes block proposals fair and decentralized, a delay to ensure sufficient time for propagation to minimize forking, and…
