Summary

Identified two security vulnerabilities in hypderledger fabric, examined their effects, and proposed two solutions.

Extracts

"First, the identity of an endorser is known to all members within a channel, which opens a gateway for DoS attack on endorsers in order to either block transaction pertaining to a client, or to degrade network efficiency. Second, the technology is prone to wormhole attack i.e. within a channel, compromising a member leads to leakage of ledger information of all members, to everyone outside the channel."
