UCO - a cryptocurrency programmed to grow

UCO cryptocurrency is designed for large-scale use and therefore mass adoption. The economic model provides for an automated currency destruction that mechanically favours the first investors through programmed deflation. for more details please visit the ARCHEthic Public Blockchain website.

New Blockchain Generation

Sustainable, Scalable, Secure and Inclusive


3.6 Billion times less energy consumption, by using the ARCH (Atomic Rotating Commitment Heuristic) consensus based on heuristic miners' election and a polymorphic worldwide replication. Each Uniris transaction only needs 0.42w of energy (0.1g of sugar).

Smart-er Contracts

In addition to running the blockchain itself, Uniris smart contracts provide the community On-Chain governance. Uniris smart-contracts are natively triggerable, upgradable, formal and easy to program helping in development of reliable applications.

Aviation Safety

Beyond just PoW (51%) or dBFT (66%), the Uniris blockchain provides a collaborative & Formal Proof-of-Work allowing to handle 90% of malicious miners, ushering an inclusive and new age of decentralized security based on the standards of aviation safety (fraud risk < 10-9).

Super Fast & Limitless

Without impacting the global validation, the heuristic polymorphic replication provides a linear increase of the capacity (in storage and number of validations) allowing to reach million transaction validations per second ... no magic just read the Yellow Paper.

Biometrics & Decentralized Identity

The 100% decentralized and inclusive wallet

Tamper proof authentications

Pure "individual keys" based on internal finger scan. The device is also able to check the individual stress levels (fear, sleep, ...) without any risk of disclosure, loss or forged authentication.

No key storage (ZKP)

The keys are generated on the fly through a secure element and deleted. The keys only allow to decipher the decentralized keychain - the identification of each secure element is part of the Proof-of-Work obviating the need to steal biometric keys.

For Worldwide Population

The keys' generation is performed from the biometric measurements, so no need to have a personal device to authenticate, any authorized device will work like your own. Providing a new age of biometric authentication without risk of disclosure.

Dencentralized Identity

Uniris blockchain makes it possible to store, share and manage all the digital identities through smart contracts. It also helps in managing organization structures, delegation of power, reputation & certification and finally make the individual's identities self-sovereign.

Providing all the use-cases from a single organization / foundation is both inefficient and far too restrictive. Our wish is that each of you should contribute to this new order of decentralization. We took special care to ensure that the programming language of smart-contracts is both simple to understand and easy to modify. No need to worry about how a user will be able to identify themselves inside use cases, or even to know the level of security associated, everything is included natively.
In the following weeks, we will start a bounty Airdrop token campaign based on the "Core Blockchain" development, the communication will happen soon. So please register your interest to be a part of it.

Frequently Asked Question

A blockchain is, in the simplest of terms, a time-stamped series of immutable record of data that is managed by cluster of computers not owned by any single entity.

Each of these blocks of data (i.e. block) are secured and bound to each other using cryptographic principles (i.e. chain).

The blockchain network has no central authority — it is the very definition of a democratized system.

Since it is a shared and immutable ledger, the information in it is open to anyone and everyone to see.

Hence, anything that is built on the blockchain is by its very nature transparent and everyone involved is accountable for their actions.

A cryptocurrency (or crypto currency) is a digital asset designed to work as a medium of exchange that uses strong cryptography to secure financial transactions, control the creation of additional units, and verify the transfer of assets.

Blockchain is the technology that enables the existence of cryptocurrency (among other things).

A cryptocurrency is a medium of exchange, such as the US dollar, but is digital and uses encryption techniques to control the creation of monetary units and to verify the transfer of funds.

By the Mathematical Proof.

If sender sends files on a P2P network with cryptographic authentification, cryptocurrency is sent and files are received by receiver.

Blockchain connects sender and receiver on a peer to peer network with cryptographic encryption, being a shared ledger brings trust, transparency and immutability, it removes the need for a traditional intermediary of trust.

Smart contracts combined legal contract with code to automate specific term of agreement between parties.

Their goals is to simplify the daily lives of users by automatized behavior and to ensure execution by the terms of the agreement.

For example, in validating a vote without having to travel, in connected objects, in health care, in supply chain, etc.

Blockchain technology opens up an infinite number of possibilities and positively affects all areas.

These papers provides a deep dive into the Technical, Structural, Economical, Financial aspects of Uniris Blockchain.

Yellow Paper is for a deep understanding of Technical aspects of Uniris and is divided into 5 seasons.

Whitepaper is for deep understanding of Tokenomics, Financials, etc of Uniris.

ARCH Consensus or "Atomic Rotating Commitment Heuristic (ARCH)" is a new generation of Consensus which delivers an open-permissionless consensus for all.
  • Atomic Commitment is the form of "absolute" consensus that implies 100% concordant responses for the acceptance or refusal of the transaction validation
  • Heuristics is the set of algorithms, softwares and parameters that manage the entire network, allowing the network to elect in a decentralized and coordinated way the nodes in charge of validating and storing transactions chains.
  • Rotating the network being fully distributed (no central or privileged role), the nodes elected for each operation are constantly changing so that no node can predict which nodes will be elected until the transaction arrives.


The project is with the highest security in the whole blockchain ecosystem.

In a world where all our digital trust is limited to large institutions such as banking, Google or Amazon, it is difficult to find your way around.

Today, blockchain technology makes it possible to achieve a higher level of security.

In this case UNIRIS has the highest level of security in the entire Blockchain ecosystem and gives you back the control over your data and digital identity.

No need for intermediaries.

Uniris is also officially certified by the French National Council of Industry, which aims to identify solutions that can contribute to the security of major events such as the Olympic Games Paris 2024.
