Only a small share of German households make use of the opportunity to regularly switch their electricity supplier in order to fulfill their needs. Besides the relatively low possible monetary savings, another reason is the fact of long running contracts. The process of supplier switching for stakeholders in the energy market is quite time-consuming. This is caused by inefficient design of the process steps due to a lack of automation, of common data management and of direct communication between these stakeholders. Two options for optimizing this by means of a blockchain-based system are described and discussed here. These allow simplified communication between participating parties and therefore potentially quicker completion of the process. They enable automation of the whole process, prevent delays due to inconsistent data and therefore, allow intraday switching. An exemplary proof-of-concept implementation on the Ethereum blockchain shows the feasibility of the approach. Nevertheless, the advantages and disadvantages when compared to an alternative automated implementation, which is not blockchain-based, are still to be thoroughly examined.

更快切换能源供应商–基于区块链的方法

只有一小部分德国家庭利用这次机会定期更换其电力供应商，以满足他们的需求。除了可能的相对较低的货币储蓄外，另一个原因是长期合同的事实。在能源市场中，为利益相关者切换供应商的过程非常耗时。这是由于缺乏自动化，通用数据管理以及这些利益相关者之间的直接沟通导致的流程步骤设计效率低下所致。本文描述和讨论了通过基于区块链的系统进行优化的两个选项。这些可以简化参与方之间的通信，因此有可能更快地完成该过程。它们可实现整个过程的自动化，防止由于数据不一致而造成的延迟，因此，允许日内切换。在以太坊区块链上的示例性概念验证实现显示了该方法的可行性。尽管如此，与不基于区块链的替代自动化实现相比，优缺点仍待彻底检查。
