How UNUS SED LEO Works?
No Central Control
LEO operates on the Ethereum blockchain, a decentralized network of computers (nodes) distributed globally, independent of control by banks or governments.
These nodes collaborate to validate transactions, ensuring system transparency and attack resistance, granting users greater autonomy and enhancing network resilience.
Blockchain Foundation
LEO's blockchain infrastructure leverages Ethereum's public, immutable digital ledger that records every transaction.
Transactions are grouped into blocks and linked through cryptographic hashing to form a secure chain.
Anyone can view the records, establishing trust without intermediaries.
As an ERC-20 token, LEO benefits from Ethereum's established security protocols and wide ecosystem compatibility.
Ensuring Fairness
LEO relies on Ethereum's Proof of Stake (PoS) consensus mechanism to validate transactions and prevent fraudulent activities such as double-spending.
Validators maintain network security through staking ETH and operating nodes, receiving rewards in ETH.
The innovation includes energy efficiency and high transaction throughput compared to earlier consensus models.
Secure Transactions
LEO utilizes public-private key cryptography to protect transactions:
- Private keys (similar to secret passwords) are used to sign transactions
- Public keys (similar to account numbers) are used to verify ownership
This mechanism ensures fund security while maintaining pseudonymous transaction privacy.
As an ERC-20 token, LEO inherits Ethereum's security features, including smart contract auditing capabilities and multi-signature wallet support.

LEO tokens were initially issued through an Initial Exchange Offering (IEO) at a purchase price of 1 USDT per token, with iFinex planning to raise $1 billion through this token sale.
