Welcome to PCHAIN weekly report.
To keep the community updated, we summarize our latest progress and activities of the PCHAIN project here.

Development Progress

The team keeps improving the consensus mechanism. A few major improvements include:
1. Maintain Pchain TestNet 1.0 for testing
2. Finish first phase of test cases for new version of Pchain
3. Keep refactoring the process of balance transferring between child-chain and main chain
4. Keep coding for the enhanced PDBFT consensus
5. Investigate solution for cross-chain transaction
6. Keep improving the auto-test framework

PCHAIN News

PCHAIN Testnet2.0 will be upgraded again and launched on Nov 30

PCHAIN Testnet 2.0 will officially go live on Nov 30, when three features will also be updated:
1. PDBFT 2.0 consensus mechanism to reduce network traffic and improve consensus efficiency.
2. New PCHAIN system architecture to dock with EVM smoothly.
3. Black box automation test framework to continuously test the PCHAIN network.

Four patent applications for PCHAIN technology have been successfully accepted

On October 15, four patents related to blockchain technology applied by PCHAIN to National Intellectual Property Administration, PRC have been successfully accepted. Mainly include:
1. Method, device, computer readable storage medium, and computer program product used for blockchain formation consensus.
2. Method, device, and computer readable storage medium for determining the transaction verification node of the blockchain.
3. Methods, devices, and storage media used to determine the consensus of blocks in the blockchain network.
4. Methods, devices, and computer storage media for blockchain systems.

PCHAIN has achieved an average of 25% TPS performance improvement compared to Ethereum

The first figure is the flame diagram of the function call of Tx executed by EVM after optimization of PCHAIN.

The second picture is the original function call flame diagram of EVM executing Tx.

The third figure shows the relative time increase of CPU after optimization.

The experiment shows that PCHAIN’s performance optimization can obtain 25% TPS performance improvement on average.

The theme of blockchain challenge is posted by PCHAIN for Junction1300+ contestants
