Exclusive report On May 28th, the 2019 Global Blockchain Technology Development Forum (GBF), sponsored by the Organizing Committee of the 2019 China International Big Data Industry Expo, undertaken by the China Academy of Information and Communications Technology, and co-organized by TelInfo and Odaily, was grandly opened in Guiyang .
Wang Xiaoming, founder and CEO of HPB Core Chain, delivered a speech on the theme of "HPB Core Chain: Innovating Blockchain Infrastructure".
He said that currently there are four main factors hindering the blockchain: TPS performance, high transaction costs, security risks, and poor user experience.
Wang Xiaoming proposed to innovate the blockchain infrastructure by combining software and hardware. The BOE acceleration engine of HPB core chain can realize 100% true randomness by collecting random fluctuations of physical quantities such as voltage and temperature of the hardware, and can solve many commercial application scenarios such as shaking car numbers, welfare lottery and game lottery, etc.
In his speech, Wang Xiaoming revealed that HPB has cooperated with dozens of ecological partners including UnionPay, LAYA.BOX, and China Electronics Technology. In addition, well-known domestic universities such as Tsinghua University and Shanghai Jiaotong University have also reached cooperation with HPB.
Wang Xiaoming also introduced the relevant details of the HPB node plan: HPB nodes are all over the world, mainly in China, Europe, America, Japan, South Korea, Southeast Asia and other countries and regions; there are 150 nodes in the world, 31 high-performance nodes; 70% of them are campaign nodes, 24 % invited nodes, 6% held by the foundation. It is reported that the HPB node plan was announced in June 2018.
Finally, Wang Xiaoming said that he believes that we have entered the era of web 3.0 and let the data return to the individual. "In the past, we paid 80% to the platform, and we got 20%. In the 3.0 era, it may be reversed. We get 80%, and the platform may be 20%. This technology can really promote the overall prosperity of the economy. and energy, so I'm very honored to be part of this industry."

Distinguished guests, good morning. I am the founder of HPB core chain. The topic I share today is "Innovating Blockchain Infrastructure".
Our HPB is the world's first self-developed programmable chip, which improves the performance of blockchain processing business through the combination of software and hardware.
As practitioners in the blockchain industry, we have been trying to change the future. Before changing the future, we must first look at the history of the industry and the problems it faces.
Let's take a look, what exactly is a blockchain?
First compare the respective advantages of the current system and the blockchain. In the current system, data is stored and processed centrally, so it is vulnerable to network security attacks, but its performance is very good, which is its advantage.
The data in the blockchain system is distributed and encrypted, so its security is greatly improved, but because of the distributed storage and processing of data, its performance is very low.
Take a look at the blockchain 1.0 bitcoin. In 2008, the bitcoin point-to-point electronic cash system was proposed. This is a representative of bitcoin landing ATM machines. From 0 to thousands of units, it has shown exponential development. Bitcoin is being used by more and more people. It is well known and has become a global digital currency.
Why do we need Ethereum when we have Bitcoin? Because Bitcoin can’t satisfy us when we want to build a complex operating system. This is the reason why Ethereum was born. It provides programmable transactions in addition to providing distributed storage. It is precisely because of the existence of systems like Ethereum that programming transactions become Possibly, programming transactions are a digital economy with a scale of hundreds of trillions, which is a very potential market.
Bitcoin and Ethereum are innovations in the industry, but it is a pity that they cannot be widely used due to system and performance reasons. Let's take a look at the current problems of the blockchain:
The first problem is its TPS performance. Many public chains, including Ethereum, experience network congestion for more than half a month, which means that it takes half a month for a transaction to be confirmed after submission, which is obviously unrealistic.
There are also high transaction costs, which will be high when there is congestion.
Then there are security risks, including the imperfection of smart contracts, resulting in losses of more than tens of millions in a single transaction. The existence of these security problems makes some key industry applications, such as financial industry applications, unable to solve the current problems.
Then there's the poor user experience. In addition, the cost for engineers to switch from traditional technical architecture to blockchain technical architecture is very high, and effective learning and production are prohibitive.
These are several major issues currently facing the blockchain industry.
So how do we try to solve these industry problems?
Our hardware is called BOE, and we have been in mass production for one year. It includes three core modules.
The first is BOE-based heterogeneous parallel computing technology to improve node performance.
We all know that blockchain performance has several aspects. The first is stand-alone computing performance, the second is network concurrency, and the third is control algorithm.
HPB has done hardware acceleration in these three aspects respectively. Every transaction in the blockchain needs to be signed, so the efficiency of the signature technology directly leads to the performance of the entire system. The current industry practice is to use software to make signatures. Its upper limit is about 2000 transactions per second. The chip performs hardware signatures, reaching 1,000 transactions per second, plus the calculation and signature cache of the CPU, these three can add up to 25,000 to 30,000 transactions. This is because such a high-performance signature technology allows us to The whole performance reaches 5000 pens per second, what is the concept? Even many key applications may run on such a system, so this technology has laid a good foundation for large-scale commercial use. The entire blockchain technology is basically built on the unit.
The second is to combine BOE to provide simple and reliable true random number services.
There have been many security incidents in the blockchain field, with a single loss in the tens of millions, so random numbers are a very good solution.
Our idea is to obtain some data of the physical world through hardware, because the physical world is an inseparable dimension. There is hardware in our system, through which the data of the physical world such as voltage and temperature are collected, so as to obtain truly irremovable random numbers.
The random number mainly includes three aspects: the first aspect is to collect the voltage and temperature, and then take several decimal places to get a random number. The second is to fully combine the mechanism of the blockchain consensus process, add this random value to the previous random number to generate the random number of the current blockchain, and make the second security guarantee. Third, if you want to get this random number, how do you do it? You need to get the value of the previous block to guess, the time left for you is very short, and these values are unpredictable, even if you get it, it must be verifiable. data discarded. Therefore, through these three points, the hardware random number is completely guaranteed.
Random numbers seem to be a more technical topic. Let me talk about a few examples to help you understand. For example, your welfare lottery, or real estate lottery. If these things have a very feasible process, we are willing to participate. Once the real doubts are solved, including finance, many key scenarios may be built on the blockchain.
Many previous guests introduced how we enable blockchain technology to empower entities, because blockchain is completely isolated, an independent world, and cannot interact with the outside world.
But with such a hardware system, it will be possible to connect with systems including the Internet of Things in the future, which means that it is possible to graft with entities. I think through the explanation of these cases, everyone can see the application value of random numbers in the blockchain.
The third is to combine BOE to provide reliable data privacy protection on the chain.
A lot of data is open and open source, but data also needs privacy protection, so we provide trusted and secure computing hardware intelligent virtual machines, and a secure privacy smart contract.
Through these two tools, your data will run in an isolated hardware environment, which greatly improves security. In addition, data transmission, input, and output are all encrypted to ensure data security. From these points of view, security solutions allow some key applications to try to use the blockchain.
These are the three core modules of BOE.
Finally, the blockchain public chain is to be globalized. Our main chain has been online for one year. Currently, nodes are spread all over the world, mainly in China, Europe, America, Japan, South Korea, Southeast Asia and other countries and regions. There are 150 nodes in total and 31 high-level nodes. performance node. Some of these nodes are generated by elections, and we also invite some credible universities and research institutions to join in to make the whole system more credible. We currently have many partners, both domestic and national.
In addition to business partners, we also cooperate with scientific research institutes. We and Tsinghua University jointly established a blockchain technology innovation and regulatory policy research fund.
A brief look back at the history of the internet and blockchain. From the Internetization of media information, to web2.0, to today, I believe that the era of web3.0 has truly come, and data returns to individuals.
thank you all!
thank you all!
