Introduction

A blockchain is a decentralized distributed ledger that combines data blocks in a chronologically end-to-end manner into a chained data structure that is cryptographically guaranteed to be tamperproof. Unlike traditional centralized databases, blockchains are fair, transparent, and tamperproof. It is this characteristic that gives the blockchain enormous potential in terms of technology and economy. It can be used in almost all industries, and it is the next-generation technological revolution a!er the Internet revolution.

With the development of digital cryptocurrencies such as Bitcoin, blockchain technology has received wide attention. Blockchain technology is a decentralized agreement, through data encryption, consensus algorithms and economic incentives, it has achieved a point-to-point transaction between nodes without mutual trust.

The introduction of the blockchain system supporting the smart contract represented by Ethereum has created new opportunities for the development of blockchain applications. Based on the trusted execution environment of the blockchain system, the smart contract platform enable complex operation of various digital assets on the blockchain, and open the door to rich decentralized application program (DApp). The development of digital currency trading system and smart contract application requires high performance and scalability of the blockchain system. However, the current mainstream public chain system has low performance and high cost, and it cannot provide fast and efficient services and a good user experience.

Blockchain technology can be of great value to all walks of life in both the technical and economic aspects. As long as there is a need to trust, blockchain technology can be used to build trust at very low cost and with high efficiency.

Blockchain technology has changed the production relationship. For thousands of years, transaction security has been guaranteed by reliable third-party intermediaries, such as banks, insurance companies, Alipay, real estate agents, etc., which help us build trust. Now BlackPearl is able to complete transactions at a very low cost and with higher efficiency through blockchain technology in a peer-to-peer manner without the need for third-party intermediaries.

The blockchain market is a market of several trillions of dollars. Great changes in production relations and business models have happened. The centralized servers are the greatest value based on the traditional Internet-based centralized model. However, in the ecosystem of blockchain, the most valuable asset is the public-chain infrastructure which carries massive data, transactions and business activities, there is huge commercial value existing with public chain.

The main problems are as follows:

The performance of the mainstream public chain is low. The TPS of Bitcoin can only reach 7 at the highest. The TPS of Ethereum can only achieve 10−20. The transaction is o#en severely blocked and cannot meet the needs of commercial landing.

The cost is high, the cost of a transaction usually exceeds the profit ceiling of most industries, limits the application to various industries, the value of the blockchain can not be realized.

The confirmation of a transaction is slow and does not provide immediate service and a good user experience. In the case of payment, Bitcoin payment requires one hour to complete, sometimes even one day if the congestion occurs, it is completely unacceptable for online merchant waiting for payments of the goods and services purchases.

Public chain comparison

Since the industry does not have an ideal third-generation public chain release, some so-called “third-generation public chains” have emerged during the transition period. In fact, they belong to the alliance chain in essence, at the expense of security to obtain certain performance improvements, and the essence is that those implementations have not broken through the "impossible triangle”. These alliance chains should belong to the over-provisioning scheme. A small number of super-nodes have a large security risk and cannot be completely decentralized. Once a situation of cheating happens, it will cause loss of the user's digital assets and damage the credibility of the entire chain. And even worse, the credit collapses of those public chains actually can cause a huge negative impact on the entire blockchain industry.

The whole development of the blockchain industry depends on the real breakthrough of the public chain technology, solutions to the "impossible triangle", the reductions of the transaction costs. Only when those progresses happen, the blockchain technology can be landed on a large scale

The entire BlackPearl.Chain is designed from ground up. It is totally different from Bitcoin, Ethereum and other public chain models. BlackPearl.Chain has solved the "impossible triangle".

 BlackPearl.Chain System Design goal and core solutions

Design goal

The BlackPearl.Chain team designed and developed the next-generation public chain that can carry large-scale commercial applications, meeting the following objectives:

● Fully decentralized; linear expansion; support for tens of millions of TPS with the increase of nodes; confirmation in seconds; extremely secure; resistance of quantum computing and biological computing attack; no waste of electricity resources; ultra-low Gas fee; Turing complete Smart contract platform.

● With VRF consensus and unique economic incentive model, create balance of each individual’s economical right and interest, integrate game theory into the blockchain to create SHD completeness.

● Support Billions of users and Trillions of devices to use BlackPearl.Chain simultaneously

Core solutions

In the current Ethereum design implementation, all consensus nodes store a complete blockchain, which stores all transaction states. This guarantees the safety of Ethereum, but it also limits the scalability of the blockchain. When the system's processing power is increased, massive data storage will limit the participation of ordinary users.

System Scalability: BlackPearl.Chain used a sharding technical solution to solve the scalability problem. As the number of nodes increases, the computational power of parallel computing increases, and the processing power of the system increases.

Storage solution: Data distributed storage technology is adopted to solve the storage problem of block data under high concurrency. Designed to solve the full expansion issue of blockchain by adding collecting nodes, sorting centers, super storage nodes, and storage sharding technique.

With scalability and storage solution, tens of millions TPS can be achieved.
