Central Bank Digital Currency (CBDC ) is a digital form of fiat money, likely to be implemented on a distributed ledger to better control the issuance, flows, and ownership of the digital currency. CBDCs are not yet a standardized term and no rule-making, however, we can recognize some characteristics:
Central bank-issued digital money and a liabilityΒΉ of the central bank
Backed by the government in the same way that current forms of fiat currency are backed
Distinct from existing accounts at Federal Reserve Banks
[1]: Liabilities are what the bank owes to others. Specifically, the bank owes any deposits made in the bank to those who have made them. The net worth or equity of the bank is the total assets minus total liabilities. ().
Started in February 2020, EuroTz is a Proof of Concept proposal to build a collateralized Euro stable coin on the Tezos Blockchain.
It is a token that can be used on the Tezos public Blockchain or
on a Tezos private Blockchain;
It is backed 1:1 by euro fiat deposits made in reputable banks Β²;
It is auditable in real time (the 1:1 backing is verifiable in
real time);
It can be emitted by a duly licensed and regulated financial
institution based in the EU.
[2]: For each coin issued on the blockchain, one equivalent monetary unit, also known as fiat (EURO, USD, GBP, etc) is escrowed.
First, it creates a Euro backed digital currency(100% covered by
euro deposits in a hive-off account via PSD2 standard) that can
ease interbank exchanges and consequently exchanges between
consumers.
On top of this stable coin can be built a software ecosystem
allowing to tokenize OTC derivatives (bonds, options, structured
products...);
It offers a secure mechanism of Delivery versus Payment(DvP) to
ensure a well unwound of digital assets trading.
One of the most innovative aspects is the possibility for a
digital asset owner to swap its asset for another one, while
downplaying fees and securing the swap.
Delivery versus payment is a mechanism that links a securities transfer and a fund transfer in such a way as to ensure that delivery of securities occurs only if payment of funds occurs,
It provides compliant, atomic and flexible transactional features
with no intermediaries;
It can automatically handle reporting and regulatory requirements
and all the post-deal lifecycle steps;
It is traceable and fully supports AML and KYC can provide market
data to products requiring them and connectivity to secondary
markets supporting heterogeneous products;
Smart contract securities that will be created on the Tezos blockchain can embed this functionality.
First, through a retailer platform, a consumer who wants to buy EuroTz has to connect to his traditional bank account(in euro) via the PSD2 standard and receive the equivalent amount in EuroTz on his Tezos wallet.
However, the consumer doesn't necessarily need to be familiar with the native Tezos address or hold a Tezos account, the transfer management will be managed in the backend by a Feeless transfer/approval contract process.
Provide Business Process management/statistics that help to manage
the euroTz Back-office interaction.
Transactions are translated into business workflows
At each process step, an administrator can have a global view of
the current transactions state in real time, so he can perform
manual verifications on the transactions (KYC / AML, verification
of sufficient funds of an address. This process offers a
compliance mechanism to euroTz ).
Camunda BPM (Business Process Manager): an open-source workflow and decision automation platform.
A contract called EventSink is used as an alternative to the events. After each successful transfer or approval, an internal call to the eventSink contract is fired as an event summarizing information relevant to the event.
