Protocol Comparison

hashtag
Key differentiators for 1Money Network's BCB, BFT consensus:

  • BCB ensures consistency (all honest nodes agree on the same value) and validity (if the broadcaster is honest, honest nodes output its message)

  • Transactions are processed without blocks, enabling streaming validation and instant finality (<1 second)

hashtag
Architectural Implications

  • BCB Optimizations: 1Money’s BCB avoids block-based bottlenecks and complex state replication, prioritizing payment speed and compliance.

  • Security: 1Money’s permissioned validators and deterministic BFT enhance resilience against long-range attacks possible in PoS.

Feature

1Money (BCB/BFT)

PoS (Ethereum/Solana)

Classic BFT (PBFT/Tendermint)

Consensus Focus

Speed: leaderless, equal priority to all transactions

Block validation + state replication

State machine replication

Finality

Instant (<1 sec)

Ethereum: ~12 min; Solana: ~400 ms

Varies (seconds to minutes)

Throughput

250,000+ TPS (theoretical, in testing)

Ethereum: ~280 TPS; Solana: ~800 TPS

≤1,000 TPS

Fault Tolerance

≤⅓ malicious nodes

≤⅓ stake-controlled nodes

≤⅓ malicious nodes

Specialization

Payments-only, no smart contracts

General-purpose (DeFi, NFTs)

General-purpose

Fee Model

Stablecoin-denominated, fixed

Volatile (ETH) or low fixed (SOL)

Varies

In summary, BCB systems like 1Money specialize in high-throughput payments with instant finality, while PoS and classic BFT target broader decentralized applications at the cost of speed or complexity.
