Consensus Mechanism

Arichain utilizes a Delegated Proof-of-Stake (DPoS) consensus mechanism with a unique multi-VM validation approach that ensures security and performance across all supported virtual machine environments.

Delegated Proof-of-Stake Overview

Validator Set Configuration Arichain operates with a carefully balanced validator set designed for optimal performance and decentralization:

• Active Validators: TBD block-producing validators ensuring fast block times

• Total Validator Set: TBD validators providing security and redundancy

• Byzantine Fault Tolerance: Network remains secure with up to 1/3 malicious validators

• Geographic Distribution: Validators distributed globally for network resilience

Performance Characteristics The consensus mechanism is optimized for Multi-VM operations:

• Block Time: TBD seconds for fast transaction finality

• Transaction Throughput: TBD TPS with TBD active validators

• Finality: Immediate finality without probabilistic confirmation delays

• Multi-VM Validation: Parallel validation of EVM and SVM transactions

Authority-Based Initial Operation

To ensure network stability during the initial launch phase, Arichain implements an authority-based operation model:

Phase 1: Authority-Based (Current)

• Pre-selected trusted validators ensure network stability

• Deterministic block production schedule prevents initial chaos

• Focus on performance optimization and ecosystem development

Phase 2: Community DPoS (Future)

• Gradual transition to community-selected validators

• Stake-based validator selection with democratic governance

• Full decentralization while maintaining performance standards

Multi-VM Block Validation

Arichain's consensus mechanism includes specialized features for Multi-VM environments:

Combined Transaction Processing

• Validators receive transaction bundles from both EVM and SVM mempools

• Parallel execution of VM-specific transactions

• Multi-VM state reconciliation before block commitment

Enhanced Security Model

• Multi-signature validation requiring consensus from validator majority

• Multi-VM state verification through cryptographic proofs

• Automatic rollback mechanisms for failed Multi-VM operations

Economic Incentives and Failure Protection

Validator Rewards

• Block rewards paid in native ARI tokens

• Transaction fee distribution among active validators

Network Security

• Economic security through validator stake requirements

• Slashing mechanisms for malicious behavior

• Progressive penalty system for different violation types
