In line with our recently updated vision statement, we start exploring how Taraxa’s audit logging of informal, off-chain transactions can benefit online and crypto communities by adding substantive metrics to online identity and reputation.

Lending and borrowing of crypto-assets have so far been a key function in DeFi. With the rise of collateralized lending, the non-collateralized sector has largely been left unattended, which presents a huge missing link in the rapidly growing DeFi ecosystem. The biggest challenge here is the lack of reputation mechanisms to provide a proper level of security to non-collateralized loans. …

The automotive supply chain for manufacturing cars, trucks, and other vehicles is one of the most complex in the world. Hence, quality assurance and certification in the auto parts supply chain require heightened vigilance and transparency to ensure that safety and quality standards aren’t compromised.

The biggest challenge of the auto parts supply chain.

The increasing complexity of the global supply chain poses new challenges to auto part makers. Poor visibility and quality management rank highest among the top-20 supply chain risks mentioned by the OEMs (Original Equipment Manufacturers). …

As we’re approaching the official testnet launch, we keep polishing up the node syncing and network security. On the application side, we’re now in the process of re-writing Marinate’s UI and building out an open API to allow for integrations with popular messenger platforms, with Telegram being our first target here.

Node syncing:

1. As PBFT only needs to record a current round of cert vote status, removed the whole PBFT cert voted values in rounds, instead of using have_cert_voted_in_this_round_ for current round cert vote status.
2. As malicious players could propose a PBFT block that includes a bogus DAG anchor, PBFT could get…

How do you build a reputation online?

Online reputation today is full of inconsistencies and black holes: with tons of social media metrics to track, major social media platforms share very little data on real user engagement, with poor data visibility and ad fraud only mounting year after year. …

You can find the updated Roadmap at http://taraxa.io/roadmap.

We compiled the target milestones for Q3/Q4 with our latest achievements and tasks currently in progress, dividing them into three distinct categories: Ledger, Application, and Community. This is a work-in-progress file that will be periodically updated to keep pace with the ongoing work.

Ledger:

Purpose-built for audit logging of 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 everyday dealings that happen every day through talking, calling, and texting — from trivial pay-upon receipt services, or property relations to auto repairs, employment relations, or simply signing off on an invoice. …

1. What problem is Taraxa trying to solve?

By tracking informal transactions, we make them highly trustworthy, which gives businesses a lot of short-term, operational value — minimizing confusion, disputes, and making better decisions faster. In the longer term, there is also a huge financial value. These informal transactions form the basis of a reputation because it shows who you’re working with and collaborating with, it reflects REAL and verifiable work and interactions that are impossible to fake. Why does reputation matter? Because a huge part of the financial system is based on reputation.

Today if you go to a bank and try to get a loan, the…

Scaling node operation:

• Saved and broadcast 2t+1 number of votes for fix triggering false syncing and network traffic.
• Fixed the performance issue getDagBlockOrder called twice when pushing a PBFT block into the chain.
• Performance improvement: Fixed conflicts and merged PR891 and PR892(save and broadcast 2t+1 votes) into the dev branch.
• Debugged and investigated the testnet finalization stalled issue due to boot node1 having some missing DAG blocks. Boot node1 was sending the syncing request for unfinalized DAG blocks but was getting the empty list from the response.

Marinate’s open API + Telegram integration:

• Migrated Taraxa-node pipeline to CircleCI.
• Adapted model parameters to the user endpoints.
• More changes to Person/Service…
