区块链大型巡回播放【第12期】#股份授权证明# &“行情解读”&“PI网友观点摘录

1、股份授权证明

区块链依靠共识机制技术核心，实现成为一个不可篡改、透明的数据可信任系统。当前主流的共识机制有，工作量证明、权益证明、股份授权证明等。权益证明机制使用确定的算法随机选择一个代表来产生下一个区块，缺点风险很明显，区块链的区块产生掌握在大户的手里。股份授权证明Dpos机制就是为了解决Pos机制缺陷而诞生，我们一起探讨股份授权证明？

1、Dpos核心思想：为了达成高效的共识，例如EOS每间隔1分钟通过投票选出前21名超级节点，前21名超级节点负责生产区块，主网会对这些超级节点进行激励代币。理论上，在Dpos中首先要选出一名代表，每个用户投票选择代表都会消耗一定的手续费，用户可以了解当前代表的生产状态，如果这个代表消极怠工错过了很多区块，那么系统将会自动发起投票下一个代表。

2、Dpos潜在风险：依稀还记得，柚子主网上线，团队发现全网生产区块有延时，生产区块节点出现小问题，立刻启动紧急修复。如果代表错过了签发区块的机会，有可能这条主链的长度可能会短，所以为了防止分叉所导致的影响，应该事发后及时亡羊补牢。网络延时也有可能使得代表没有及时广播新区块，导致所谓的区块链分叉。

Blockchain relies on the technology core of consensus mechanism to become a tamper-proof and transparent data trust system. The current mainstream consensus mechanism is, proof-of-work system, equity certificate, stock authorization certificate, etc. . The proof of interest mechanism uses a deterministic algorithm to randomly select a representative to generate the next block. The disadvantage risk is obvious. The block generation of the block chain is in the hands of the big users. Share authorization certificate Dpos mechanism is to solve the defects of the Pos mechanism was born, we discuss share authorization certificate?

1. DPOS core idea: in order to reach an efficient consensus, for example, EOS votes for the top 21 supernodes at 1 minute intervals, and the top 21 supernodes are responsible for producing blocks, which the main network will reward with tokens. In theory, in Dpos, a representative is first selected. Each user who votes for the representative will incur a certain handling fee. The user can know the current production status of the representative. If the representative is inactive and has missed a lot of blocks, then the system will automatically vote for the next delegate.

2, DPOS potential risk: vaguely remember, Pomelo Main Network Online, the team found that the network production block delay, production block node small problems, immediately start emergency repair. If the representative missed the opportunity to issue the block, it is possible that the length of the main chain may be short, so in order to prevent the impact of bifurcation, it should be timely after the incident. Network delays may also prevent the representative from broadcasting new blocks in a timely manner, leading to so-called blockchain bifurcations.

2、行情解读

每日行情走势，大饼从3月12号开始爬升，初始点为3800点，今日08月10号19点38分11743美元左右，近期走势明显，变盘已经到来，庄家向上明显。从日曲线看11000-11700之间目前支撑点很多，庄家买入挂单持仓0.85万BTC，上方阻力0.9万BTC。

持续五个月的走势，接下来到了变盘的时刻，再次测试12000高位历史压力点，突破之后稳住，小牛来临。

从15分钟曲线可以看出，比特币从11522美元爬升到12052美元一个相对高点，然后继续震荡起来目前处于11741点，相对指标USDT目前6.92，至于小牛是否开启，至于后市是否持续开启情况，看庄家心情。行情有所抬头，期待大行情来临。

3、小结

近期波动剧烈，小编结论很简单，没有金叉，没有支撑点，没有抛盘点，行情走势扑朔迷离，需要用户用心作出适合自己的判断！最近行情比特币在慢慢的拉升，不急不躁。

最近关注了可能8月15号上线的VOICE，可以加小编VX1093628138，备注送梯子。近期NEST\BTM\LINK这些吆币涨势喜人，注意自己的判断。
