J.P.Morgan, the world’s largest investment bank, launched a pilot in 2017 for their newly
developed Interbank Information Network (IIN) in order to leverage blockchain technology for
fast and secure information transfer between banks. The network runs on the Ethereum-based
protocol Quorum, that was also developed by J.P.Morgan with enterprise needs in mind. Over

payments between institutional accounts. The asset will not be accessible to the public, and all

Currently, a privacy feature will be added using a new Zether -based extension. Zether is a fully
decentralised payment mechanism. The latter normally uses zero-knowledge (ZK) proofs to
conceal account balances and transfer accounts, but the new anonymous extension was added
to hide participants’ identities.
Most privacy coins might be suffering from regulations as they can be used for illicit activities.
For example, Japan’s Financial Services Agency (FSA) was considering banning exchanges
from listing privacy coins altogether. However, unlike these, the privacy feature is only
accessible to participants that have already passed the J.P.Morgan KYC.
