21.1 Staking Requirements
RandProof employs a low-stake, high-decentralization model. Unlike traditional Proof-of-Stake systems where staking secures consensus, RandProof’s security is guaranteed by fifteen independent entropy sources (DRAND, NIST, Chain-Native VRF, Commit-Reveal, Block Timestamp, and ten more -- see Section 3.3). Node staking serves primarily as sybil resistance and skin-in-the-game for honest behavior, not as the primary security mechanism.
Staking Philosophy: Lower barriers to entry maximize decentralization while maintaining economic security through:
-
Sybil attack deterrence: Cost to create many fake nodes remains non-trivial
-
Slashing penalties: 100% stake loss for misbehavior (double-signing, offline nodes)
-
Multi-layer security: 15 entropy sources make node-level attacks irrelevant
| Chain | Minimum Stake | Asset | Approx. USD | Rationale |
| Base / OP / ARB / Linea / Polygon / World Chain | 0.005 ETH | ETH | ~$20–30 | Low-cost EVM chains |
| Solana | 0.5 SOL | SOL | ~$50–75 | High-throughput, low-fee |
| Sui | 5 SUI | SUI | ~$25–40 | Fast finality |
| TON | 10 TON | TON | ~$20–30 | High-speed, low-cost |
| Cardano | 50 ADA | ADA | ~$20–40 | Academic-grade security |
| BNB | 0.1 BNB | BNB | ~$30–50 | High liquidity |
| Avalanche | 1 AVAX | AVAX | ~$20–40 | Subnet architecture |
| Moonbeam | 0.5 GLMR | GLMR | ~$20–30 | Parachain economics |
| Polkadot | 5 DOT | DOT | ~$30 | High-value chain |
| Ethereum | 0.01 ETH | ETH | ~$30–50 | Mainnet premium |
Note: Stake amounts are calibrated to balance decentralization (maximizing node count) with sybil resistance (deterring fake nodes). The 15 entropy sources provide the actual security guarantee, making node-level attacks economically irrational regardless of stake size. Minimum stakes are calibrated so that no chain's USD-equivalent floor falls materially below ~$20 (the assumption used in the Sybil-cost analysis, Section 23.2.2); quantities are repriced if sustained price movement pushes any chain outside the $20-60 band.
