Pchain — the Best Thing to Happen to Crypto in 2018!

First multichain supporting EVM (Ethereum Virtual Machine) in the world with the ability to apply large-scale block-based applications based on smart contracts and AI


It’s very well thought out actually. According to the founder Dr. Feng Cao, here are some of the meanings of the letter “P”:

Pi (PChain) — Forms a foundation for a lot of math formulas and problems along with cryptography.

Parallel — To make blockchain more scalable, parallel design is important.

Poly — Polychain (Poly means many) or multi-chain design.

Partitioning — A term that has been used in databases forever. A more fancy word these days is “Sharding”. It’s nothing but partitioning data into small chunks.

Public — Public-chain.

  4. CFLP (http://www.chinawuliu.com.cn/english/)China Federation of Logistics & Purchasing, the first social organization of the logistics industry in China, was established in Beijing and approved by the State Council in April 2001. CFLP is founded by the China Society of Materials Economy established in 1980, the China Logistics Research Institute established in 1984., the China Association of Materials Circulation established in 1995.

The largest association in China CFLP unites not only logistics enterprises. It consists of about 7500 participants, of which about 5000 are non-logistic industries. All together, CFLP members provide 7% of China’s GDP. The association has a strong organization status, approved by the decision of the State Council of the People’s Republic of China, the head of the CFLP is also the vice-president of the International Union for Procurement and the vice chairman of the Asia-Pacific Logistics Union.

CFLP: “In 2018, blockchain will reach a new level of development in multi-chain, sharding, smart contracts, which will allow the use of large-scale applications compatible with blockchain. Next-generation projects, such as Dfinity, EOS and PCHAIN, will further develop technologies based on on the blockchain.”

Pchain also cooperates with: North America Blockchain Assosiation, The University of Queesnland (Australia), Assosiation of Computing Machinery, CCF.

Most of the traditional blockchain systems (Ethereum, Bitcoin) are single-chain systems. It has encountered performance and scalability bottlenecks in large scale blockchain applications. In a multi-chain system, communication between each derivative chain is not required in most cases. Therefore, computation in these derived chains can be completely parallel resulting in a huge improvement in throughput.

As smart contracts or dApps are deployed on PChain, multiple side-chains will be created (one per dApp) in addition to the main chain, which will record data related to that specific dApp. This will allow PChain to scale and avoid hungry dApps from crushing overall performance (hello, Kitties!). This will also improve performance because of transaction-level sharding with a PoS consensus mechanism.

Knowledge Graph means intelligence derived from a list of things, their type, properties, and how they are linked. PChain uses an Oracle mechanism based on its Knowledge Graph module to integrate blockchain data and external data as Smart Data, which can be used by AI to generate some interesting use cases for forecasting markets, social networks, digital identities and so on.

However, PChain has taken this one step further, by providing the first multichain solution to be compatible with Ethereum Virtual Machines (EVM), which is the software infrastructure underpinning Ethereum smart contracts. What this means is that rather than just operating as a single sidechain like Rootstock, the PChain solution consists of multiple derivative chains.

This enables parallel transaction processing on a scale not possible with the kind of single-stranded structure operated by Rootstock. Whilst other blockchains have attempted such a multi-chain solution, they have fallen down due to not being compatible with EVMs. This means they have had to rely on traditional languages such as NodeJS and Java, which don’t allow for effective pricing mechanisms or traceability.

This makes PChain a truly breathtaking technical breakthrough as the first multichain solution to be compatible with EVMs. It allows it to operate at a level of speed and scalability that other blockchains cannot compete with and offers the first solution that will be able to sustainably serve large scale industrial applications of blockchain technology.


But PChain is not just solving the issue of scalability, but also the issues of interoperability as it offers cross-chain functionality to a wide array of public blockchains, including Bitcoin, Ethereum, Bitcoin Cash and a host of others. The scope of the project is therefore far beyond not just Rootstock but also more complete interoperability solutions like Polkadot, which uses a one-size fits all approach, where PChain can support the smart contract call of non-native tokens.

PChain is one of the first along with the likes of Zilliqa to pioneer the technique of sharding to improve performance. However, again, its secret-weapon of having a multichain structure gives it an unfair advantage that such single-chain projects cannot compete with.

Dr. Feng Cao: “It‘s the 1st multichain supporting EVM in the world. A number of performance-enhancing efforts are designed from the perspective of improving Transaction Processing and stochastic consensus, such as Dfinity [17], Zilliqa [18] and Aelf [19]. Different from these work, PCHAIN improves the overall performance of the blockchain from the perspective of Data Processing and Sharding through a multi-chain structure, and designs a new consensus approach based on multi-chain structure.

Discuss PCHAIN Scalability with Xinshu Dong from Zilliqa,Terry from IOST and Zhuling from aelf.

Multiple Applications already agreed to be built on the PChain blockchain, with many further projects in the pipeline

Unlike a lot of new blockchain projects, PChain has not just partners but has also already negotiated for several exciting applications to be built on it. The details are not yet ready for public consumption, but we can give you a sneak preview by telling you that a major cultural blockchain project recognised by Japan’s Blockchain Association will be one of the first projects to be implemented on the PChain blockchain.

A very exciting anti-quantum blockchain project created in collaboration with Tsinghua University, China’s leading research university will also be using PChain due to it being the only blockchain with the advanced features required for this kind of project. Other applications are also in advanced negotiations.

This demonstrates that big players in Asia are already willing to use PChain instead of the likes of Ethereum and NEO, due to the scalability and interoperability benefits and the trust they have in China’s biggest blockchain superstar. It also hints at the regional advantage that PChain will enjoy over the likes of Rootstock, Polkadot and Zilliqa when it comes to Asian applications interested in sidechain, interoperability and sharding solutions.

PChain’s DEMO


PChain’s Demo — https://www.youtube.com/watch?v=-yKzLNJA7Ao

Dr Feng shows us a live prototype of PChain working flawlessly with very fast transactions with one main chain and two child (side) chains (PChain explorer). A total of 32 validators (nodes) are used using a novel PDBFT consensus algorithm which is a lot more efficient than PBFT algorithm. N vs N-Square. A live demo was shown how to build a simple smart contract which can feed data from external source, www.fifa.com, in the example shown. And show in details how the debugging of the smart contract and how the results is derived. Do note that the very hype Quarkchain only has 5 nodes in their private testnet demo.

Ria Roque

Hi admin just wondering how you’re tech is different from quarkchain

jeff cao

you can count how many different nodes between the demo of these two projects :)

Ria Roque

Hi Jeff yes isn’t it because you do transactional sharding that’s why you have more nodes and quark does state sharding? Sorry I don’t really understand how the number of nodes could affect transaction process 😅

jeff cao

the number of nodes is an important parameters on decentralization,which is one of the key feature of a good public blockchain

jeff cao

or we can say it will be much easier to have a demo on 5 nodes than on 20 nodes,let alone 32 nodes. The meaning of 32 nodes is larger than 20 nodes which is the bottleneck of traditional pbft algo

This live demo is actually 100% qualify to be called a live private testnet and much better than many other projects’ testnet. It shows how solid is the PChain team. Their prototype already a lot better than many MVPs.

PChain will be a game changer for blockchain with the smart data extension, and the ability to support native EVM, and cross chain capability of BTC, BCH and ERC20 tokens (do note cross chain capability is not implemented yet in the demo).
