区块链大型巡回播放【第5期】#私有区块链# &“行情解读”&“PI网友观点摘录”

1、私有区块链

私有区块链又称为私有链，参与节点有特定的规制和限定，区块链全网数据设置了访问权限和修改权限。区块链内部互相连接，分布式数据库通过密钥加入到区块链节点网络。私有链有什么特点需要分享？

1、权限等级：它不像公链参与者是全民，比如，读取查看的权限可以开放给读者，也可以完全封闭，然而需要强调的是写入的权限仅在参与节点用户手里。

2、安全和成本：对于参与节点用户来说，私有链的权限最高，参与者可以随时随地修改规则，就是“皇帝”的待遇。对于私有链的风险点在于内部的用户，而不是外部像公链的51%攻击风险。私有链还可以对数据进行严格保密，权限掌控能力强。至于交易成本，由于仅有限个节点进行确认，所以交易成本相对很低。

Private blockchain is also known as private chain, the participating nodes have specific regulations and restrictions, and access rights and modification rights are set for the whole data of blockchain. The blockchain is interconnected, and the distributed database joins the network of blockchain nodes with a key. What are the characteristics of private chains that need to be shared?

1. Access level: unlike public chain participants, it is not universal. For example, access to view can be open to the reader or completely closed, but it should be emphasized that access to write is only in the hands of the users of the participating node.

2. Security and cost: for the users of the participating nodes, the private chain has the highest authority, and the participants can modify the rules at any time and place, which is the "emperor" treatment. The point of risk for a private chain is the internal user, not the 51% risk of an external attack like a public chain. Private chain can also carry out strict confidentiality of data, authority control ability. As for transaction costs, they are relatively low because only a limited number of nodes are recognized.

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03号19点37分11207美元左右，昨日中午插上天地针，直接把做合约的用户全部爆仓，近期走势明显，变盘已经到来，庄家向上明显。从日曲线看10300-11200之间目前支撑点很多，庄家买入挂单持仓1.0万BTC，上方阻力0.5万BTC。
