PCHAIN News

PCHAIN’s First Cross Chain game is online !

On December 7th, PCHAIN Lottery, the first cross chain game on Testnet 2.0, was officially launched. It completed cross-chain interaction with BCH based on PCHAIN chain 1. A winner would be randomly generated in this game every 24 hours. Participants can bet tBCH to game after depositing for free. The larger tBCH amount you bet, the greater chance you will win. In each period, 3 lucky participants whose ranking is No 9/ No 99 /No 199, can share 30% reward from the pool. Each one will get 10% of the total betting. Meanwhile, the winner gets 70% rewards. Welcome to join and try the high performance with BCH at Lottery.

Besides, welcome to contact us for comments and questions, and PCHAIN will gradually improve the game.

PCHAIN’s Smart Data Partnerships

By the end of November, there have been 16 smart data partners of PCHAIN, which will cooperate on different research directions and technology developments around smart data, work together to the construction of PCHAIN’s bottom ecosystem, and jointly innovate blockchain technology to make large Scale blockchain industrial applications possible.

PCHAIN Innovative Consensus Algorithm :PDBFT 1.0

PDBFT 1.0, a innovative consensus algorithm of PCHAIN, solved the deficiencies of the traditional POW and PBFT. A consensus algorithm based on POW requires a significant amount of computing power, resulting in a lower TPS (transactions per second) and has the possibility of fork. A consensus algorithm based on PBFT improved efficiency, but resulting a higher cost of communication. PCHAIN adopted a new consensus mechanism — PDBFT, which includes many new features. Regular replacement of validator set allows the validator to join and exit the mechanism more freely. Active change of the leader makes it more difficult to attack the leader. A reduction in the communication cost of broadcasting the votes from O(n2) to O(n) greatly improves the extendibility of the protocol and makes large-scale applications possible.

PCHAIN was invited to dbcrypto Telegram AMA

PCHAIN founder and CEO Dr Feng Cao and CTO Steven Lv was invited to dbcrypto Telegram AMA on Dec.05.2018. PCHAIN Testnet2.0 has attracted a lot of attention, 71% new users have visited it within 48 hours after Testnet2.0 launched. During this AMA, many people raised questions about TPS on Testnet 2.0.

As PCHAIN CTO Steven Lv responded: PCHAIN Testnet 1.0 get TPS of 123,424 with 256 child chains, and every child chain contributes about 400 TPS. Now we have optimized the system and one child chain can reach about 600 TPS. So with the scale of 1.0, Testnet 2.0 can get TPS of about 180,000.

Announce next AMA

On Dec 11th, at 10PM(UTC+8), PCHAIN partner GTEX will join PCHAIN next Telegram AMA. GTEX , committed to become the world’s first digital asset distribution platform in the field of gaming and would work together with PCHAIN in the field of game applications in the future.

The first use case concept in PCHAIN:CO2 Smart Contract

After Hack Junction 2018, PCHAIN made a deep communication with winner team CO2 Smart Contract. Both parties hope to put the concept into action as soon as possible. CO2 Smart Contract makes supporting climate action 100% transparent. It can work on a stable public chain. In short, a landowner gets scientific data proving how much CO2 eq tons he/she can save by sustainable land management. The data helps landowner to receive environmental aid based on the information. Blockchain helps to record contracts between the landowners and supporters of climate action decentralized and publicly.
