STD-Chain——以太坊智能合约Solidity以及IPFS星际文件协议

马云曾在中央网信办主管媒体《网络流传》杂志颁发署名文章,谈企业责任。文章中说:“好的企业,要用贸易手法办理社会问题、敦促社会成长,而不是寻找社会裂痕去成长。办理的社会问题越大,企业就越伟大。假如能为国度办理问题,那就是一个国度企业。”马云建设的阿里巴巴团体,将电商、物流、金融等各项业务做得十分精彩,那么盛大公链是不是一个好项目?

Ma Yun once published a signed article in "network communication" magazine, which is in charge of the central network and information office, on corporate responsibility. "Good enterprises should use commercial methods to solve social problems and promote social development, rather than looking for social loopholes to develop," the article said. The bigger the social problems solved, the greater the enterprise. If it can solve the problem for the country, it is a national enterprise. " Alibaba group, founded by Ma Yun, has excelled in e-commerce, logistics, finance and other businesses. Is?STd—chain?a good project?

STD-Chain——以太坊智能合约Solidity以及IPFS星际文件协议

STD-Chain参考DPOS+BTF共鸣机制的利益,独创了POFProofoffaith(信仰证明机制)让STD-Chain网络能超高速运转,制止区块网络拥堵,安详高效的生意业务确认;另外,STD-Chain还通过兼容以太坊智能合约Solidity以及IPFS星际文件协议,来实现不变,更具可扩展性以及更开放的区块链应用系统构建。

Referring to the advantages of dpos + BTF consensus mechanism, STD chain has created pofpooffaith (proof of belief mechanism) to enable the STD chain network to operate at ultra-high speed, avoid block network congestion, and secure and efficient transaction confirmation. In addition, STD chain is also compatible with Ethereum smart contract solidness and IPFs interstellar File Protocol to achieve stability, More scalable and more open blockchain application system construction.

以太坊智能合约Solidity

1.编写智能合约代码,并编译成字节码。

2.陈设智能合约。进程是向“0”地点发送一笔带有智能合约字节码数据的生意业务,这个生意业务会生成该智能合约的地点,并将字节码存储在该地点下的状态树中。

3.执行智能合约(挪用智能合约函数)。向智能合约地点发送一个生意业务,该生意业务携带被挪用的智能合约函数信息及挪用参数,携带的信息遵循ABI编码协议。

4.智能合约地点收到这样的挪用合约函数的生意业务,首先会解码数据,按照功效查找到对应函数的进口,再传入参数执行该函数。

5.执行函数的进程是状态转换的进程,执行完成后会扣除挪用者相应的Gas耗费。

6.状态转换的进程会全网同步并被再次执行验证,确保执行功效一致,这样通过验证后的生意业务会记录到区块中,同时更新状态数据。

IPFS星际文件协议

IPFS(InterPlanetaryFileSystem,又称星际文件系统)是一种点对点的漫衍式文件系统,旨在毗连所有有沟通的文件系统的计较机设备。在某些方面,IPFS雷同于web,但web是中心化的,而IPFS是一个单一的Bittorrent群集,用git客栈漫衍式存储。换句话说,IPFS提供了高吞吐量的内容寻址块存储模子,具有内容寻址的超链接。这形成了一个广义的MerkleDAG数据布局,,可以用这个数据布局构建版本文件系统,区块链,甚至是永久性网站。IPFS团结了漫衍式哈希表,带有鼓励机制的块互换和自我认证定名空间。IPFS没有单妨碍点,节点不需要彼此信任。

盛大公链在IPFS中存储和共享数据将内容添加到IPFS网络后,它会存放在那边?

作为对等数据存储系统,IPFS答允每个用户(对等)在当地托管他们想要的任何数据。首次向IPFS添加新内容时,实际上只是在用户本身的计较机上以适合于通过IPFS协议共享的名目对其举办配置。凡是,用户会在本身的计较机上安装IPFS,然后在该计较机上建设IPFS的新实例(也称为节点)。那就是用户的数据在当地存储的处所,由内容地点(CID)引用。IPFS中存储的数据可以回收多种形式,可是最常见的用例之一是传统文件的共享,我们将在后续中具体相识。

STd—chain stores and shares data in IPFs. After adding content to IPFs network, where will it be stored?

As a peer-to-peer data storage system, IPFs allows each user (peer) to host any data they want locally. When new content is added to IPFs for the first time, it is actually set up on the user's own computer in a format suitable for sharing through the IPFs protocol. Typically, users install IPFs on their own computer and then create a new instance (also known as a node) of IPFs on that computer. That's where the user's data is stored locally, referenced by the content address (CID). Data stored in IPFs can take many forms, but one of the most common use cases is the sharing of traditional files, which we will learn more about later.
