+# DeFi and Peer To Peer Exchange
+
+![alt_text](img/defi_exchange.png )
+
+
+DeFi is an amazing trend which banks should try to leverage, if not for internal usage, to provide a more transparent and safer way for their customers to exchange their currencies (digital and fiat) in a fully regulated environment.
+
+We have all the building blocks available to make this work.
+
+Thanks to the digital twin this is implemented in a fully peer2peer way, while using DeFi Smart Contracts on the blockchain.

+# Digital Currency Wrapping
+
+![alt_text](img/cryptocurrency.png )
+
+
+In Addition to allowing a user to directly integrate with an outside digital currency, we also suggest allowing wrapping of the outside currencies e.g. a wrapped BitCoin (BTC).
+
+This Wrapped BTC is then stored on the main or dedicated digital currency chain (can even be one chain per wrapped asset). The IBC (see below) allows the wrapped BTC to be used by the user from their wallet and digital twin.
+
+The Original BTC is stored offline in the Knox Security Vault using our Quantum Safe Storage Codec. This allows for ultimate security and flexibility for users.
+
+The bank can choose to allow users to exchange digital currencies with the external world or not, through IBC (Inter Blockchain Protocol, see below), this can be easily achieved. The bank can even choose to become a liquidity provider for the existing digital currency world (optional).
+
+Revolut, for example, has chosen to keep the digital currencies in their internal system, and the user can only exchange from their own fiat currency to the digital currency and back. We believe though that it's nicer to allow the user to exchange digital currencies with the outside world if it matches the Bank’s Regulatory requirements.
+
+It is possible to introduce multiple stages e.g. in the digital bank ecosystem, users can freely exchange currencies with each other (stays on chain). Once they want to go off chain, extra checks are done to make sure there is no fraud involved, it can then take a certain time before it executes.

+The ability to use multiple secure areas which can be used to provide offline storage of keys and digital currency cold wallets.

+![alt_text](img/distributed_storage.png "image_tooltip")
+
+
+Each Knox Security Vault is an ultra safe area. Thanks to our Quantum Safe Storage system, it is not possible to retrieve a key even if a hacker would be in one safe, as a combination of three safes is required to recover information.
+
+We suggest using the key storage in the following way: each wallet from a user stores the encrypted dispersed key distributed over four or five Knox Security Vaults. Only in the case of a disaster and user strong identification, an user could get access (in the case of death of the customer, to hand-over to the relatives).

+# Peer2Peer Reputation System 
+
+Reputation is a very important part to any financial system. This allows users to see the reputation of the people they are transacting or doing business with.
+
+We are developing a unique peer2peer reputation system to allow the power of network effects to come up with strong verification and reputation proofs. We think this might become an important added value that any financial institution  government could deliver to its customers/citizens.
+
+Such a system can easily be integrated and extended by a standard KYC and AML system.
+
+This goes had in had with the Proof of Authenticity system.

+# Proof of Authenticity
+
+Proof of Authenticity (PoA) is an algorithm that allows peers to verify that people, products and statements on the ThreeFold Grid are genuine. It acts as a reputation engine to validate any information on the grid. 
+
+## Why Proof of Authenticity
+
+Any system that contains a vast amount of information, should require proof of authenticity.
+
+We believe users should be able to measure authenticity in relation to
+
+- The people they connect with;
+- The products and services they access;
+- The information they consume.
+
+Therefore, to automate information search in a decentralized and trustful environemnt, an algorithm that is able to scale information verification in a neutral way is required. 
+
+Proof of authenticity puts forward a very simple method to verify the genuiness of information.
+
+Here's an example of how PoA works in a decentralized context:
+
+- Someone fills in their profile with their personal and professional data. 
+- A former colleague finds their information and verifies their information as being authentic. 
+- Once a user gets verified e.g. 10 times, they can be trusted to be real and genuine. 
+
+The above can also apply to products, statements and more. In that sense, PoA can solve multiple digital challenges such as:
+
+- The verifiability of information and news 
+- A non-biased way to rate products and services. 
+- website authenticity 
+- etc.
+
+## Applicability
+
+POA can be used for any type of information but one of the first ones is identity, KYC/AML is a mechanism to identify people but peer authentication is a very powerful way to extend this with.
