2、通过教程购买DDD

DDD是Scry.info项目的数字代币符号。Scry.info是一个基于区块链的量化数据提供和交易平台,目标是提供一个智能化区块链社会的数字合约引擎,让开发者和个人都可以在里面寻找到来自体育、娱乐、交通、气象、金融、农业、基因模型等数据源,并且鼓励全球更多的社区开发者、跨国组织、公司和个人写入数据源参与到区块链数据节点的集群智能认证中。

 

 

项目愿景


SCRY.INFO希望提供一个智能化区块链社会的数字合约引擎,让开发者和个人都可以在里面寻找到来自体育、娱乐、交通、气象、金融、农业、基因模型等数据源,并且鼓励全球更多的社区开发者、跨国组织、公司和个人写入数据源参与到区块链数据节点的集群智能认证(Using AuthenticationinCertification agreement Based Swarm Intelligence)中。

 

 

应用场景


1、面向所有预测市场应用的共享真实数据服务
在当前整个区块链生态中预测类应用是一个相当庞大的市场,然而很多预测类应用往往需要自行将现实数据引入区块链,而且由于这些开发商开发的初衷聚焦于应用之上,所以其他应用很难共享某一个预测市场应用中引入的数据。这样既造成了区块链资源的浪费也因为某个预测应用的用户基数过小导致表决结果真实度的不足。
SCRY.INFO提出统一的公共数据服务的概念,旨在打破每个预测应用之间的数据壁垒,例如A预测应用的数据在B预测应用缴纳了足够的费用的前提下也可以提供给B应用使用,费用统一使用SCRYCOIN进行结算。在这个基础之上,用于预测市场的数据也可以提供给商业报告,民意调查等类型应用使用,协议之中规定的各项流转费用,保证了各方参与者的权益。
2、数据提供者以及数据消费者的信息市场
如何让数据互通起来,发挥数据更大的价值呢?
SCRY.INFO为数据提供者提供了一套灵活的机制:除去为数据需求者提供其指定的数据,也可以独立发布数据,通过SCRY.INFO将这种数据推向整个市场:任何需要数据的数据需求者都可以通过向数据提供者以及数据公证人缴纳一次性查询费,来获取数据以及验证服务。这样就保证了数据提供者的独立性,降低了其对现有数据需求者的依赖。
这里数据消费者实际上是一个比较广泛的群体,如商业报告提供者就是一种典型的数据消费者,因为一般的商业报告中往往需要引用大量的可审查的数据,而SCRY.INFO的数据交易模型正好满足了这方面的需求。
例如:假设有一个数据提供者A创建了一份供应协议合约Y,并且通过了公证环节。这时报告提供者B在自己的报告合约Z中需要Y中的数据,这时,B支付查询费并查询Y中的数据并将数据保存在自己的Z合约中,并且确保在Z验证函数中含有对Y中验证API调用的代码。将来如果因为需要B出示Z合约中证明这份数据的来源时,求证者只需调用Z提供的验证代码即可。
3、商业智能投票热点营销工具
商业智能投票与市场热点营销调查也是一个高度依赖数据的行业。例如,一个商业主体想要调查到人们对于旗下品牌往年冬季服饰颜色的看法,以便为今年冬季服饰颜色的设计做个参考。按照以往经验,会有以下做法;发传单,然而这样人力成本高昂,效率低下;在官网上发起投票,送礼品,然而官网知名度低,参与人少;会向第三方中心化的机构购买数据,然而收费不低,并且真实性无法保障。
SCRY.INFO正希望为他们提供高效的服务,例如:
品牌商机构可以在SCRY.INFO发起一个公投协议合约(悬赏性质)并填入相关选项,描述,公投人数上限,合法公投比例等参数,然后发布。SCRY.INFO生态中的参与者注意到这个悬赏令,直接进入到公证环节,来对设定的选项进行投票。投票成功结束后,参与者拿走赏金(SCRYCOIN),NGO得到样本数据,双赢。且品牌商在明年,后年等都能查看此次结果,这样通过不断积累,SCRY MSPs(促进参与者互动和交易的多面平台)可以形成以年为单位的用户意向趋势表,为他们未来迎合市场的政策提供真实可靠的数据指导意见。
4、面向个人以及企业的存证服务
同时,SCRY.INFO提供的数据协议通过特殊设置后,也能够提供现实生活中,诸如财产公证,遗嘱公证之类的存证服务。这类服务不光具备传统意义上的功能,还具有一些独特的优势。首先,这些电子协议具备区块链去中心化以及不可更改的特性,这些特性对于存证来讲尤其重要;其次,SCRY.INFO提供的协议本身具有可引用的特性,由此带来的是以一种明确的形式逻辑可证且可审查的方式对这些存证直接使用,这是传统意义上的存证服务难以做到的。
具体使用方式为:首先构建一个委托供应协议合约,并将数据写入者以及数据公证人设置为白名单模式,同时指定数据写入者以及数据公证人的身份,之后数据写入者以及数据公证人在写入数据以及公证数据时都附带上各自针对这张合约的签名数据,提交合约以后便产生了一份多方签名认定的数据存证。
在技术方面,既然是以数据储存为核心的区块链,那么如何储存数据就成为了他们最需要突破的技术难关。
SDBC是一个新的去中心化的数据存储区块链,目前的小数据放置在ETH上,大点的数据通过索引的形式放在IPFS上,但这些第三方存储或多或少都不太满足SCRY.INFO对数据的存储和查询行为。他们计划开发一个比较符合SCRY.INFO查询业务的用于存储和查询的区块链,能为SCRY.INFO提供存储量更大,数据更安全,查询速度更便捷的基础服务。
为了达到他们的数据储存需求,开发中有几个重要目标:
1)保证存储数据的完整性:通过对数据分块存储,这些数据块存在于全网节点的某一个位置。使用MerkleTree对其进行完整性验证,但也会针对查询做存储的优化处理,配合查询使用。
2)数据存储的安全性:设置不同的安全级别来对存入的数据进行签名(DSA,RSA,ECDSA等),以及多方签名的形式.使用MerkelTree来对节点的合法性进行验证。使用密码学安全的伪随机数生成器(CSPRNG)来生成私钥,并通过椭圆曲线算法来得到对应的公钥。计划使用对公钥变形之后的地址来作为每个节点的标识,即公钥由经过SHA运算之后变为地址的形式:Base58(identification+公钥+head4(SHA256(SHA256(公钥)))等。
3)能提供类似SQL的简易化操作命令来完成对较为复杂的业务查询:提供一个类似Azure云数据库的轻量级的分布式关系型数据存储和处理。计划采用基于三维分档布隆过滤器表(TF)的SCRYO-Top查询算法。试验结果表明,该算法能够避免重复访问数据对象,并能以较低的误判率实现大规模数据的高效查询处理。与NRA和BPA相比,当属性列表超过4个时,开销明显降低,适合面向大规模数据的查询处理应用。

Project Vision


SCRY.INFO hopes to provide a digital contract engine for an intelligent blockchain society so that developers and individuals can Find data sources from sports, entertainment, transportation, meteorology, finance, agriculture, genetic models, etc., and encourage more community developers, multinational organizations, companies and individuals around the world to write data sources and participate in blockchain data nodes In Using AuthenticationinCertification agreement Based Swarm Intelligence.

Application scenarios


1. Shared real data service for all prediction market applications
Prediction in the entire current blockchain ecosystem Prediction market applications are a huge market. However, many prediction applications often need to introduce real-world data into the blockchain by themselves. And because the original intention of these developers is to focus on applications, it is difficult for other applications to share a prediction market application. data introduced in. This not only results in a waste of blockchain resources, but also causes a lack of authenticity in the voting results because the user base of a certain prediction application is too small.
SCRY.INFO proposes the concept of a unified public data service, aiming to break the data barriers between each prediction application. For example, the data of A prediction application can also be provided to B prediction application on the premise that B prediction application pays sufficient fees. When used by B application, all fees will be settled using SCRYCOIN. On this basis, the data used for market prediction can also be provided for business reports, opinion polls and other types of applications. The various transfer fees specified in the agreement ensure the rights and interests of all participants.
2. Information market for data providers and data consumers
How to make data interoperable and maximize the value of data?
SCRY.INFO provides a flexible mechanism for data providers: in addition to providing data requesters with their specified data, it can alsoPublish data independently and promote this data to the entire market through SCRY.INFO: any data demander who needs data can obtain data and verification services by paying a one-time inquiry fee to the data provider and data notary. This ensures the independence of the data provider and reduces its dependence on existing data demanders.
Data consumers here are actually a relatively broad group. For example, business report providers are a typical data consumer, because general business reports often need to quote a large amount of reviewable data, and SCRY.INFO The data transaction model just meets this need.
For example: Suppose a data provider A creates a supply agreement contract Y and passes the notarization process. At this time, report provider B needs the data in Y in its own reporting contract Z. At this time, B pays the query fee and queries the data in Y and saves the data in its own Z contract, and ensures that it is in the Z verification function. Contains code for verifying API calls in Y. In the future, if B needs to prove the source of this data in Z contract, the verifyer only needs to call the verification code provided by Z.
3. Business Intelligence Voting Hot Marketing Tool
Business Intelligence Voting and Market Hot Marketing Survey is also an industry that relies heavily on data. For example, a business entity wants to survey people's opinions on the colors of its brand's winter clothing in previous years, so as to provide a reference for the design of this year's winter clothing colors. According to past experience, the following methods will be used: handing out leaflets, but this is expensive and inefficient; launching voting on the official website and sending gifts, but the official website has low visibility and few participants; purchasing data from a third-party centralized organization. However, the fees are high and the authenticity cannot be guaranteed.
SCRY.INFO is hoping to provide them with efficient services, for example:
Brand organizations can initiate a referendum agreement contract (reward nature) on SCRY.INFO and fill in the relevant options, description, maximum number of referendums, and legality Referendum ratio and other parameters are then released. Participants in the SCRY.INFO ecosystem noticed this bounty order and directly entered the notarization process to vote on the set options. After the voting ends successfully, the participants take away the bounty (SCRYCOIN), and the NGO gets the sample data, a win-win situation. And brands can view the results next year, the year after, etc. Through continuous accumulation, SCRY MSPs (a multi-faceted platform that promotes participant interaction and transactions) can form a year-by-year user intention trend table to cater to them in the future. Market policies provide real and reliable data guidance.
4. Certificate deposit services for individuals and enterprises
At the same time, the data protocol provided by SCRY.INFO can also provide certificate deposit services in real life, such as property notarization and will notarization, after special settings. This type of service not only has traditional functions, but also has some unique advantages. First, these electronic agreements are decentralized and immutable on the blockchainCharacteristics, these characteristics are particularly important for evidence storage; secondly, the protocol itself provided by SCRY.INFO has citation characteristics, which brings about a clear formal logic provable and reviewable way. The deposit certificate can be used directly, which is difficult to achieve with certificate deposit services in the traditional sense.
The specific usage method is: first build a commissioned supply agreement contract, set the data writer and data notary to whitelist mode, and specify the identities of the data writer and data notary, and then the data writer When the data notary writes the data and notarizes the data, they will attach their own signature data for this contract. After the contract is submitted, a data certificate certified by multi-party signatures will be generated.
In terms of technology, since it is a blockchain with data storage as its core, how to store data has become the technical difficulty they most need to break through.
SDBC is a new decentralized data storage blockchain. Currently, small data is placed on ETH, and larger data is placed on IPFS in the form of indexes. However, these third-party storages are more or less The data storage and query behavior of SCRY.INFO is not very satisfactory. They plan to develop a blockchain for storage and query that is more in line with SCRY.INFO's query business, which can provide SCRY.INFO with basic services with larger storage capacity, safer data, and faster query speed.
In order to meet their data storage needs, there are several important goals in development:
1) Ensure the integrity of stored data: By storing data in blocks, these data blocks exist in a certain location in the nodes of the entire network . MerkleTree is used to verify its integrity, but it will also be optimized for storage and used in conjunction with queries.
2) Security of data storage: Set different security levels to sign the stored data (DSA, RSA, ECDSA, etc.), as well as in the form of multi-party signatures. Use MerkelTree to verify the legitimacy of the node. Use a cryptographically secure pseudo-random number generator (CSPRNG) to generate the private key, and use the elliptic curve algorithm to obtain the corresponding public key. It is planned to use the address after deformation of the public key as the identification of each node, that is, the public key is changed into the form of the address after SHA operation: Base58 (identification+public key+head4 (SHA256 (SHA256 (public key)))), etc.
3) Can provide simplified operation commands similar to SQL to complete more complex business queries: Provide a lightweight distributed relational data storage and processing similar to Azure cloud database. It is planned to use the SCRYO-Top query algorithm based on the three-dimensional binning Bloom filter table (TF). Experimental results show that the algorithm can avoid repeated access to data objects and achieve efficient query processing of large-scale data with a low misjudgment rate. Compared with NRA and BPA, when the attribute list exceeds 4, the overhead is significantly reduced, which is suitable forQuery processing applications for large-scale data.
