Table 2: Cont. of authenticated members, attacking a small number of them dramatically decreases the efficiency of the system. In response to these attacks, the authors propose a novel protocol named Eges, which uses different groups of authenticated members for different blocks and hides them in the pool of fake committee nodes. In this way, Eges ensures the high resistance of the system towards DoS and network partition attacks, and simultaneously achieves low latency. Nevertheless, heretofore, none of the BCs protected the properties of owners in the case that the user's private key was lost or stolen and there was no way to recover it. This shifts all the responsibility from the intermediaries to the single owners of wallets and slows down the large-scale adoption of BC technology. [PERSON] et al. [58] consider that the establishment of relevant common policies with the purpose of overcoming the abovementioned issues would boost the adoption of BC technology since, presently, different countries react individually in this sense and generate further confusion. On the other hand, [PERSON] et al. [59], in their research, developed recoverable transactions.
