区块链技术,将如何解决现有清算机制的问题呢?
要回答这个问题,事实上需要依次回答三个问题:
1. 现有清算机制是怎样的?
2. 这种机制存在怎样的问题或缺点?
3. 区块链技术是怎样解决这种问题的?
到目前为止,银行金融体系的清算机制,经历过两个阶段:
A. 无专门的第三方清算机构
B. 有权威中心化第三方清算机构
A. 无专门的第三方清算机构情况下
机制:
各家银行相互之间直接进行清算。它们需彼此搭建通信网络,独立记账而没有一个共同总帐,然后互信核对账目,进行清算和结算。
缺点:
1. 成本高:
(1)每家银行要有独立的信息系统,来核算自己的收支状况。
(2)任何两家银行之间,都需搭建通信网络。如果总共有m家银行,任意两家有账务往来,则需搭建通信网络数量 = m! / [2! (m-2)!]。这是一个庞大的网络数量和相应的费用。
2. 账本记录准确性难以保证:
(1)用户把钱存在银行,也就是说银行欠用户的钱。账务记录却由欠钱的银行负责。这难以确保账本准确性,但用户只能选择相信。
(2)没有总帐,各银行一本分账,更容易出现不一致性,给核对带来更多复杂度。
3. 效率低:
(1)跨行清算速度慢。各家银行之间,都需要花费大量时间、金钱,互相查帐。一家银行若同n家银行有账务往来,则有n家清算对象。
(2)重复记账,一笔转账会有两笔记录,分别在关联的两家银行账薄上。
B. 有权威中心化第三方清算机构情况下
机制:所有银行都接入清算机构,通过它与其它银行进行清算和结算。清算机构记录所有跨行交易,形成中心化的总帐,各行通过总帐可以筛选出自己的分账。各银行无需相互间搭建通信网络,就可以通过清算中心进行通信。
相比前者,优点是:
1. 成本降低:通信网络数量,从m! / [2! (m-2)!]下降到m。
2. 效率提升:清算中心拥有所有跨行转账记录的总帐,避免记录的重复性,降低了核对的复杂度,促进了效率提升,加速了清算的速度。
接入银行数量不断增加后的缺点:
1. 成本提升:接入银行数量超过一定数目后,再增加新的银行,会导致工作量和成本的显著增加。此外,各种服务项目收费,以及处理不同系统接口的业务集成和流程的辅助成本增加。都导致成本增加。
2. 效率降低:清算机构变得庞杂,管理难度增加。此外。衍生出处理各种不同系统接口的业务集成,流程环节增多,结算变得层级多且复杂。效率随之降低。
3. 总帐安全性难以确保:清算中心的中心化危险,当遇到黑客攻击、恐怖袭击、地震等不可抗力情况下,难以确保总帐安全和正常清算不被破坏。
以上,我们了解了中心化清算机制存在的问题,那么区块链技术将如何解决它呢?
C. 区块链技术下的清算和共享总帐
机制:
所有交易执行和清算,发生在区块链网络。所有成员可以共享总帐,无需通过专门的清算中心。
前者的问题/缺点,在区块链技术中得到很好的解决:
1. 成本降低
(1)它是由去中心化的无数节点在共识机制下自动化执行清算、记账,成本主要是电力和设备,不是中心化组织架构不会像中心化机构一样因交易量不断增加导致行政管理等成本显著增加。
(2)不存在各种中间环节、辅助流程等,因此节省了此类额外费用
2. 效率提升
(1)去除复杂性:交易执行由非对称加密的公私钥对保障,清算、记账由节点负责,去除了各中间环节,避免大型中心化机构的笨重、多层级、效率低的缺点,降低了交易结算的复杂性
(2)速度提升:交易发起后,清算、结算几乎达到同步。
3. 总帐安全性得到保障
(1)总帐有无数份,随时更新、保存在各节点,避免了中心化遭受集中攻击或不可抗力的危险。
(2)总帐难以篡改。交易由时间戳进行标记,确保唯一性,并经各节点验证,确保准确性。加入总帐的区块,由共识机制确保准确性,并经各节点验证。

区块链还是很好解决的,加上它的共识账本,基本杜绝了数据作假的可能

这个其实我觉得只要出一个是可以稳定币价的项目,那么完全可以解决这个问题的。
然后再解决几个像,交易速度快确认快,界面友好等特点就好了。

不能做假,还怎么骗补贴呀。
很多国企就是靠补贴才能活着。

区块链最容易落地的就是在金融领域杜绝假账的存在,通过区块链记账

区块链还是挺好的,但是虚拟币好像不能从区块链分离出来吧
