區塊鏈外包 區塊鏈定製外包開發 就找北京動點軟件

區塊鏈的基本原理理解起來並不難。基本概念包括：

• 交易（Transaction）：一次操做，致使帳本狀態的一次改變，如添加一條記錄；
• 區塊（Block）：記錄一段時間內發生的交易和狀態結果，是對當前帳本狀態的一次共識；
• 鏈（Chain）：由一個個區塊按照發生順序串聯而成，是整個狀態變化的日誌記錄。

若是把區塊鏈做爲一個狀態機，則每次交易就是試圖改變一次狀態，而每次共識生成的區塊，就是參與者對於區塊中全部交易內容致使狀態改變的結果進行確認。

基於區塊鏈底層技術，提供智能合約定製開發服務，並可實現對應區塊 鏈應用的落地。

根據您不一樣的業務需求，編寫貼合所需應用場景的智能合約，並能經過智能合約構建出執行必定商業邏輯的區塊鏈應用。助您快速部署智能合約，更加便捷地開發基於區塊鏈的應用。

用通俗的話闡述：若是咱們把數據庫假設成一本帳本，讀寫數據庫就能夠看作一種記帳的行爲，區塊鏈技術的原理就是在一段時間內找出記帳最快最好的人，由這我的來記帳，而後將帳本的這一頁信息發給整個系統裏的其餘全部人。

這也就至關於改變數據庫全部的記錄，發給全網的其餘每一個節點，因此區塊鏈技術也稱爲分佈式帳本（distributed ledger）

When the unknown person going by the name of Satoshi Nakamoto created blockchain technology in 2008, he had a single vision: a peer-to-peer electronic cash system. What he didn’t realize is that his creation was not limited to this one application. The ability to be integrated into various industries from logistics to healthcare, from energy to agriculture has led to blockchain being referred to by many as a disruptive innovation.

Although blockchain is gaining popularity quickly, it has yet to be embraced by the public sector. As Aanchal Anand from the World Bank put it, 「The blockchain is an exciting new technology that can potentially produce solutions to several of our pressing development challenges. At the same time, there are many unanswered questions.」

「The most effective way to get these questions answered is to bring global innovators, investors and policy makers together, to co-create solutions that contributed to the achievement of sustainable developing goals (SDGs) through a multi-sector, multi-stakeholder process.」 said Xiaochen Zhang, the founder of FinTech4Good. 「Our goal is to bring blockchain solutions providers and the development community together for a constructive conversation. China’s blockchain leaders are very important for this debate.」

Blockchain4SDGs Alliance brings together institutions and global leaders to provide thought leadership and investment advisory to scale up blockchain4SDGs solutions. The global Blockchain4SDGs Roundtable was held in January in Washington DC and participated by around 200 industrial leaders, investors, and policy makers from all over the world.

The event featured some of the most promising blockchain for SDGs solutions in areas such as energy trading, digital asset management, economic identity of the poor and healthcare including several Chinese blockchain applications.

Robert Zakon, the White House Presidential Innovation Fellow, shared the latest initiatives that were currently being taken to accelerate innovation, such as blockchain technology in the U.S..

Ying Cao, from Energy Blockchain lab, introduced their ground breaking blockchain based emissions trading application with great length. Shanyuan APP combines blockchain technology with big data to induce positive philanthropical behaviors. Seratio Blockchain 2.0 created a new way to forecast the where, what and how of impact interventions. BIX™ Bank System supports four types of financial transactions with three types of currencies – US dollar, BIXCoins™ (virtual currency), and Bitcoins (crypto currency) which may push the technology carver in the financial industry to another level.

According to the chairman of the Beijing Blockchain Application Association, Yedong Zhu, 「The application of blockchain technology in bitcoin, and in the financial sector is already very exciting. Its application in other sectors will bring even more trans-formative changes to our life in the future.」

However, 「Why hasn’t Wall Street embraced blockchain?」 Daniel Spuller, Director of the DC based Chamber of Digital Commerce, said:「They are starting to, but it would take an entire change to the culture up there, all the pipes are in order and they would have to rip up everything and start brand new.」 The challenge of its adoption in non-financial sector will be even greater.

Ashis Gadnis, the CEO of Banqu, added, 「I have never found an event that made a meaningful connection between blockchain and the SDGs. I was the first one, about six months ago, banging on every door, with my partners, I was the first one to speak at the UN Assembly that went: ‘Guys, you have got to connect blockchain to the SDGs’ and when I saw Xiaochen’s email, I was like, YES!」

Since SDGs are highly relevant to the welfare of the whole society, government and other public agencies need to get actively engaged in the conversation to fully harness the power of blockchain technology. From its birth, the technological advancement of blockchain is through global collaboration. In Yedong Zhu’s word, 「The blockchain 3.0 will require even more of such intensive collaborations. 」
