The European Central Bank has released the results of its ‘tiered approach’ on an experimental digital euro. According to the report, blockchain networks Tezos, Hyperledger Fabric, and NEM are fully compatible with the current fiat-based system.
Cryptocurrencies, such as bitcoin, ethereum, and several other altcoins have gained immense popularity over the last couple of years, establishing themselves as potential competitors of fiat currencies.
This, in turn, has led many leading central banks all over the world to contemplate launching their own versions of digital currencies. While several countries are already researching the possibilities, the European Central Bank (ECB) has been working on an experimental ‘digital euro’, testing different compatible solutions since September 2020.
The ECB assessed different design features to validate whether it was possible to combine centralized technology with distributed platforms based on distributed LEDGER technology (DLT). From the numerous approaches tested and evaluated, the ECB found that the blockchain networks Tezos, Hyperledger Fabric, and NEM are fully interoperable with existing fiat systems, allowing several use cases and supporting various features of a potential CBDC in the future.
A New Report Indicates Interoperability With ECB Fiat Systems
According to the report titled Digital Euro Experiment Combined Feasibility – Tiered Model, ECB and several central banks from the European Union, including France, Spain, Italy, Luxembourg, and Belgium tested Tezos and the other two networks in a tiered CBDC architecture based on a hierarchical structure in which a distributed ledger system interoperates with the fiat systems.
The report clarifies that Tier 2 systems, such as Tezos, seamlessly integrate with the existing Tier 1 systems that represent the current central bank architecture, offering not only interoperability but also enabling plug-and-play modules for private sector interfaces such as payment applications, banking infrastructure, and other financial services. Furthermore, this report also reinforces ECB President Christine Lagarde’s statement in June where she suggested that digital euros can complement cash instead of replacing it.
Compared to other blockchain networks like Bitcoin and Ethereum, Tezos uses a less power-consuming delegated proof-of-stake (DPoS) consensus protocol to work in parallel with other blockchains, thus offering high scalability and security. In addition to the recent test by ECB, Tezos has also been part of other digital euro tests, including the successful wholesale CBDC clearance in 2020 by the Bank of France and Societe Generale.
The tiered experiment by ECB showcases the potential of Tezos and other compatible blockchains, giving the central banks control over the CBDC while enabling flexibility, innovation and resilience.
