Privacy is the product of modern society and the foundation of a free society. It is also one of the important research directions in the blockchain industry. So how can we implement and achieve privacy protection?
One way to protect privacy is with zero-knowledge proof.
Zero-knowledge proof technology is something that many people have heard of but might not understand. It can be neatly summed up in one sentence:
“A prover (Alice) convinces a verifier (Bob) to believe that the prover (Alice) knows a secret without revealing what that secret is”.
To make this explanation more intuitive, we will use…
We look at everything that needs to be considered when building a blockchain platform.
PPIO Code Talks is an open platform for high-quality presentations and discussions on blockchain technology with the aim of engaging the community and spreading ideas. The following is an adaptation of a presentation given on November 26 by Xianbo Yang, CTO of Rensenergy, on the subject of what underlies the development of a blockchain platform.
It’s literally block + chain.
For everyone that missed it, here’s a look at our latest Code Talks meetup that we hosted at the beautiful Tongji University.
On November 26th, we put on another installment of our Code Talks series. Partnering with Tongji University’s Venture Valley, the event was hosted on the beautiful SiPing Road Campus of Tongji University. By all accounts, the night was a huge success and something we’re all proud of.
November’s Code Talk event showcased a talk about the different types of zero-knowledge proofs and how they can be applied to improve a project.
PPIO Code Talks is an open platform for high-quality presentations and discussions on blockchain technology with the aim of engaging the community and spreading ideas. The following is an adaptation of a presentation given on November 26 by Dr. Guo Xionghui of Loopring, covering the application of zero-knowledge proof technology in the blockchain industry.
One of the most important application directions of blockchain technology is that data put on the chain is open, transparent, and cannot…
A look at how Byzantine Fault Tolerance works when applied to Tendermint by Cosmos.
In our discussions on technology, both our own and technology that’s impacting the digital world and blockchains, we have discussed how different chains can communicate with each other. At PPIO we’re paying close attention to innovators and pioneers in the field in order to improve our own technology. Cosmos’s Tendermint is one we’re paying close attention to having introduced them as part of our Code Talks series. Our article today will analyze perhaps the most complex and important aspect of Tendermint — their consensus algorithm.
Recognized as an integral technology, we examine cross-chains to better understand how blockchains can communicate with each other.
When blockchains were first being built, they were envisioned as being able to provide a ‘one size fits all’ solution, meaning that all transactions, smart contracts, or anything else is performed on a single chain. However, it’s clear now that such a system isn’t so practical, especially when there are scalability limits and innovation constraints.
A cross-chain is the interoperability between two relatively independent blockchains. In other words, it allows blockchains to speak to one another because they’re built in a standardized…
Public chains get a lot of love but we think there’s a lot of magic in consortium chains. Our latest Code Talks explains why.
PPIO Code Talks is an open platform for high-quality presentations and discussions on blockchain technology with the aim of engaging the community and spreading ideas. Previous Code Talks covered The A-to-Z on zkSnarks and Zero-Knowledge Proof, Libra & PPIO: The Genius of Libra and What We’ve Learned and Tendermint: The Inventiveness of their Consensus Mechanism. The following is an adaption of a slideshow presentation given on September 7, covering the role of consortium blockchains for businesses.
Live video streaming technology is an integral part of the PPIO platform. While you get the end result, the technology behind it is complicated. We break it down and share the secrets of video streaming so you get the full picture.
An examination of an essential privacy algorithm so you can maximize your privacy and ensure anonymous transactions on the blockchain.
Privacy is one of the most concerning issues in the 21st century and the subject of a lot of internal research and discussion at PPIO. Given the importance of this issue, there are many technologies related to privacy protection in the blockchain world. Our previous article, The A-to-Z on zkSnarks discussed why a zero-knowledge proof is ideal for authentication so no one else knows what you’re communicating. Today we will analyze another technology related to privacy: Ring Signatures.
Detailed analysis of China’s new digital currency ‘DC/EP’ and what the Middle Kingdom is doing when it comes to designing and implementing a nation-wide digital currency.
The recent news about the People’s Bank of China’s development of the upcoming digital currency “DC/EP” has striked global interest and enthused cryptocurrency enthusiasts in the wake of June’s announcement of Libra. In this blog post, we will review the evolutionary history of money, the advantages of digital currencies, analyze Libra’s positioning and planning, then compare it with the advantages and disadvantages of DC/EP in order to explore the value and commercial significance of…
