The Blockchain built for real world
apps with D-DPoS mechanism
Tomi Wen / Founder of DBX.ONE
Trust: what blockchain offers
• In theory, sufficient competition and effective administration
provide the base mechanism of credit.
• In practice, regulation by people filled up with loopholes, tycoons
rarely be constrained due to their size and power.
• Blockchain (decentralized, "code is law", blockchain structure
etc.) offers a Trust Machine.
Paradox @ Blockchain Today
• IT and Internet aim to speed up information transmission.
• Impossible Triangle in Blockchain:
• No proper blockchain today could support great scale data
transmission with high TPS/Safety and reliability.
Decentralization High TPS with low cost Safety
PoW: too much cost
What happened to Ethereum?
Gas is too expensive.
Confirmation is too slow.
A value system becomes an ERC20 pure token system.
DPoS: too many Trumps
• Less decentralization, higher performance
• 21 block producers and ECAF
• Node selection: rule of law of token/money
• Is EOS truly (properly) decentralized?
Flowing Block Producers
A queue of Block Producers
• Random selected nodes to reach consensus
• Decentralized random function
• LIVE campaign——ranking all the time
DDPoS: A new approach to have it all
• DDPoS (Data-based Delegated
Proofof Stake) is the consensus
mechanism of DBXChain
• 1,000,000+ TPS (Parallel Side
Chain)
• Data security
• Proper decentralization
Time-weighted contribution
• A Quartet contract : Buyer,
Seller, Tester, Trinity Node
• Contracttrade =
< Account(s), Location(s),
DApp(s), Sampling, No. of Tri,
Fees, Terms >
Code is Law / Contract

Editor's Notes

  • #4: 数字技术网络是解决高效信息传输、高效决策的关键性工具 而目前的区块链网络还无法实现实现大规模、高速度的商业化运用;目前仍没有一条公链可以支撑大规模数据交换类应用。 区块链的不可能三角:去中心化、高效低能、安全
  • #5: 在区块链世界,目前仍没有一条公链可以支撑大规模数据交换类应用,即使是号称开启了智能合约时代的以太坊,其在数字金融领域的价值毋庸置疑,但是其共识机制设计与网络结构,在趋利投机的狂热中将以太坊中的绝大部分人,推向了挖矿获取Token、利用以太坊发币的现状。大量单纯的逐利行远远背离了V神的最初构想,也与其白皮书上的愿景愈行愈远。
  • #6: 不要认为区块链接就是发币,区块链的终极目的是变革生产关系,进而极大提升生产力,通过应用为社会服务。越过以太坊,当前大热项目EOS通过DPoS机制改变了大量节点证明而导致的效率低下问题,在应用开发的道路上更进一步。但是,EOS目前的超级节点竞选,反应出EOS已经被“巨富”绑架,成为了一个“中心化”项目。单纯DPoS机制下,贿选问题无可避免,少数节点可在短时间内贿兑或购入大量节点投票,以期套取超级节点收益,21个节点可能更集中地受控于数量更少数的利益主体,整个网络运行受极少数人掌控。此外,作为一个募资超过40亿美元的项目,开发团队以细密的免责条款将责任撇除得干干净净,然而就在不久前EOS的巨大安全漏洞就被360伏尔甘团队发现,暴露出EOS项目的巨大风险与治理问题. http://tech.ifeng.com/a/20180628/45040933_0.shtml
  • #7: DBX采用了“流动”的三体节点(承担记账及其他功能的重要节点),实现了“超级节点”的实时投票竞选,避免了贿选问题带来的安全漏洞。DDPoS中一个关键创新是时间加权证明,并通过动态递归模式的数学模型来调控票的权重,为提供了更大规模、更长时间数据贡献的节点赋予加权,从而显著增加了操纵选举的成本和项目安全性,将DBX打造成一个真正意义与实践能力的公平公链。
  • #8: 大规模数据应用高并发量、安全、有限去中心化 DBX公链总结了之前的成功公链的经验,通过大量技术验证开发了一套创新型共识机制和合约机制。DBX的共识机制即是DDPoS(Data-based Delegated Proofof Stake),是基于Bitshare的DPoS共识机制及石墨烯技术的创新升级版,致力于支持实现高并发量与高速稳定传输的数据类应用。

  • #10: 在DBX链中,数据质量检验会遵循严格的代码检验的原则,通过调用相关的数据检验DApp执行,所以不会产生人为偏见、人为操纵以及交易违约。此外,通过第三方程序检测数据质量,需要至少成交一次交易验证,才会发放系统奖励。上述机制会鼓励更多的人上传优质数据,避免部分用户刷量和重复上传数据。只要用户“站着”上传了优质数据,由市场交易确认了质量与需求,就可以“躺着”赚取DBX。
  • #12: 为更多数据驱动型区块链项目提供公链支持与基础设施,可以让这些项目专心深耕应用场景、提升效能。当前DBX的另一重点放在生态建设,目前DBX已经与若干实力出众的实体经济项目启动合作,明确通过DBX链为其提供底层公链支持,以DApp形式来实现其区块链+实体经济的商业应用,共同建设DBXChain大生态。
  • #13: 目前DBX已经上线一款DApp“数据游戏”,通过建立了基于区块链的数据众包、人人数据受益的方式来开展大规模协作。在“数据游戏”中,用户可以收集损坏共享单车照片、上传方言语句片段用于机器学习。使用过的用户会发现,拍照上传会只获得很少的DBX,而数据经过验证与购买后,会获得更多的DBX报酬。
  • #14: 目前DBX已经上线一款DApp“数据游戏”,通过建立了基于区块链的数据众包、人人数据受益的方式来开展大规模协作。在“数据游戏”中,用户可以收集损坏共享单车照片、上传方言语句片段用于机器学习。使用过的用户会发现,拍照上传会只获得很少的DBX,而数据经过验证与购买后,会获得更多的DBX报酬。
