How it works

Mint your digital currency

Straightforward minting
of a digital currency or a Central Bank Digital Currency (CBDC) with the Cashbutler patented technical concept.

1. Set the denomination
Decide how many times one unit can be divided (equivalent to euros and cents)

2. Set the value
Decide the worth of one value based token – set it as a digital representation of an asset or as a market-driven currency.

3. Distribute currency
Allocate tokens directly to user wallets or via intermediators through encrypted transfers.

Security checks

Authentication and verification
Transactions are authenticated and verifyed through encrypted communication with the issuer and/or through an encrypted peer-to-peer-network.

Fraud proof
Each token recieves a new id upon authentication with the issuer, which makes it impossible to double spend a token.

All transactions are traceable through a constantly updated list of transactions – a shared digital ledger.

4. User wallet
The user can now transfer tokens to other wallets. Each transfer are scrutinised according to the security checks.

Examples: Transfer of different currencies

Currency: Central bank digital currency (CBDC).
Scenario: Carl pays for a taxi ride using his CBDC.

Currency: Big corporate internal units.
Scenario: Sales team pays an internal invoice to the marketing team.

Currency: Shopping mall bonus points.
Scenario: Anna buys socks for bonus points at the mall.

Currency: CBCD + University Campus Credits.
Scenario: James transfers CBCD to Martha, who buys lunch with Campus Credits.

Patented concept

By using the CashButler patented technical concept, you will never infringe on others intellectual property rights and are therefore shielded against legal proceedings regarding technical issues. This means that you don’t need to worry about how to create your digital currency. Instead, you can focus on your core business.

We have a patented technical concept for digital real-time and highly secure blockchain transactions of e-currencies or tokens with a dynamic Distributed Ledger Technology (DLT). In short, the patent states how transaction takes place between user devices or entities through Dynamic Checks, which is an extremely efficient way to handle a digital currency – and its creation doesn’t involve energy- and cost-intensive mining. Each Dynamic Check can be transferred as a whole, or in divided pieces according to its predetermined denomination, which each contains information about its:

  • Identity
  • Value
  • Verification of issuing entity
  • Smallest transferable unit of currency (daughter checks)

Our patent also states how user devices acts as a storage area for Dynamic Checks and that they are connectable to a currency system. A security application module in the devices verifies authenticity of a transfer between devices and also verifies that the receiving device is an authorized receiver. This verification can either be executed between users (a so called on-chain transaction, within the ledger) or with the issuer (off-chain transaction).

To put it simple – by using our patented concept you will get a traceable and secure digital currency with instant transfers.

Why should I consider CashButlers technical concept?

There are a number of reasons, for example

  • The patent is a shield against legal proceedings regarding technical issues.
  • Eliminates the need to develop a concept from scratch.
  • Ensure highly secure instant transactions with dynamic, biometric and cryptographic security.
  • Digital encrypted security – the currency can be authenticated at anytime.
  • Unlimited payments and e-currencies are able to function within the same platform.
  • All currencies can be handled by a single “digital wallet” in an app (e.g. QuickPass).
  • Enables wallet to wallet transfer without the need for banking.

How does Cashbutler differ from other technologies?

Bitcoin: A decentralized digital currency without an institutional issuer, where users create new coins by using proof of work, so called mining.
Ethereum: Use “proof of concept” rather than proof of work to approve new coins. The Ethereum platform does include a method for minting digital currency (ERC-20), but only within the platform and not off-chain.
Mobile payment systems: Systems such as the Brittish Paym, the Danish Mobilepay and the Swedish Swish, is not digital currencies but rather a simplified method for customers to transfer old Fiat money (i.e. cash) between accountholders.

CashButler: A patented technology that enables issuers to create true digital currencies that can be used in different platforms – without the time and energy consuming mining.
