# Unit Zero
Unit Zero is a blockchain network operating on top of the Waves blockchain. It introduces a novel approach to blockchain architecture, merging high performance and scalability with robust security and decentralization. The concepts implemented in Unit Zero are planned to be extended to interconnected chains of Units ecosystem.
# Core Features of Unit Zero
- Ethereum Virtual Machine (EVM) Compatibility: This feature enables the swift deployment of decentralized applications (dApps) within the Unit Zero network.
- Fractal Consensus Model: Unit Zero relies on consensus provided by Waves, concentrating its efforts on efficient transaction processing.
- Economic Incentives for Network Growth: The network rewards block generators with its native token, UNIT0. This token serves as fee asset and plays a pivotal role in the Units ecosystem DAO. Initially, UNIT0 will have a zero supply, fostering scarcity and adding value from the onset of the network's launch.

# How the Network Operates
Some nodes from the Layer-0 network (Waves) also participate in the Layer-1 network (Unit Zero).
Consensus within the Layer-1 network is maintained by the Chain Contract deployed on the Layer-0 network:
- Generators commit to participating in Layer-1 block generation by invoking the Chain Contract.
- Each block on Layer-0 marks an epoch in Layer-1. During an epoch, a generator is selected to produce Layer-1 blocks.
- The Chain Contract employs a modified Fair PoS, calculate a time delay for each Layer-1 generator, determining when it is eligible to generate blocks.
- The generator packages Layer-1 transactions into blocks, signs them, and invokes the Chain Contract to record the block metadata on Layer-0.
- The Chain Contract enables resolving potential forks in the Layer-1 network. The primary chain is the one extended by generators possessing over half of the Layer-1 generating balance.
For more details about the protocol, refer to the Extended Consensus White Paper.
# Tokenomics
A node is required to maintain a minimum of 20,000 WAVES in generating balance within the Waves network.
The generating balance in the Unit Zero network initially relies on the intermediary token L2MP (see the token info in Waves Mainnet) for the first two years following the network's launch. L2MP holders can stake their tokens to the Stake Contract on the Waves network, indicating their delegated node. The amount of L2MPs delegated to a node constitutes its generating balance in the Unit Zero network. A node's probability of being selected to produce Unit Zero blocks during an epoch is directly proportional to its generating balance.
Rewards for block generation in the Unit Zero network are disbursed in the base token, UNIT0, including:
- 2 UNIT0 per epoch;
- Transaction fees.
# Unit Zero Node Architecture
The Unit Zero node consists of two components:
The Execution Client processes transactions and updates the blockchain state. Execution Clients intercommunicate within a peer-to-peer network and handle JSON-RPC API requests.
For instance, Hyperledger Besu may serve as an Execution Client.
The Consensus Client is responsible for block addition and achieving consensus among network participants.
A Waves node with the ConsensusClient extension installed acts as the Consensus Client.
