Digital identity means recording some important information in blockchain so that it can be verified and tracked by the public. Using a consortium blockchain to do this can also save money when compared to a public blockchain.

Pros
- For consortium blockchains, the consensus algorithm is usually called PoA (Proof of Authority). Instead of solving a difficult mathematical problem in PoW or holding a large amount of cryptocurrencies in PoS, in PoA, a list of authorized block miners is used to determine which nodes are allowed to create new blocks. The chain has to be signed by the majority of miners, then it becomes a permanent record. It is more efficient and secure since the miners are fewer and more reliable.
Cons
- Schnorr has too little effect to be considered as one of the potential solution.
