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…

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.

What Is Blockchain?

It’s literally block + chain.

  • A block is a base where data is stored, a chain keeps them connected
  • In a blockchain system, data cannot be blocked or modified after being…


For everyone that missed it, here’s a look at our latest Code Talks meetup that we hosted at the beautiful Tongji University.

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.

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.
