Fenine delivers enterprise-grade throughput and latency:
Throughput Analysis Mathematical Model :TPS max = G limit G tx × T block \text{TPS}_{\text{max}} = \frac{G_{\text{limit}}}{G_{\text{tx}} \times T_{\text{block}}} TPS max = G tx × T block G limit For standard transfers (G tx = 21 , 000 G_{\text{tx}} = 21,000 G tx = 21 , 000 G limit = 30 M G_{\text{limit}} = 30M G limit = 30 M
TPS = 30 , 000 , 000 21 , 000 × 3 ≈ 476 TPS \text{TPS} = \frac{30,000,000}{21,000 \times 3} \approx 476 \text{ TPS} TPS = 21 , 000 × 3 30 , 000 , 000 ≈ 476 TPS Metric Fenine Ethereum BNB Chain Polygon Block Time 3s 12s 3s 2s Finality 18s 12.8m 18s 128s TPS (Transfers) ~476 ~24 ~160 ~150 TPS (ERC20) ~154 ~8 ~53 ~50 TPS (Swaps) ~67 ~3 ~23 ~22 Gas Limit 30M 15M 140M 30M
Latency Distribution Real-world mainnet metrics:
Block Propagation: ├─ P50: 150ms ├─ P95: 300ms └─ P99: 500ms Transaction Confirmation: ├─ 1 block: 3s (50% finality) ├─ 3 blocks: 9s (87.5% finality) └─ 6 blocks: 18s (98.4% finality)
Recommended Confirmations :
Small transactions: 3 blocks (9s)
Medium value: 6 blocks (18s)
High value: 12 blocks (36s)

Zero Migration Effort Deploy Ethereum contracts without any changes:
// Your existing Ethereum deployment script import { ethers } from "hardhat" ; async function main () { const Contract = await ethers . getContractFactory ( "MyContract" ); const contract = await Contract . deploy (); await contract . waitForDeployment (); console . log ( "Deployed to:" , await contract . getAddress ()); } // Works on Fenine without modifications!
Network Configuration (hardhat.config.js):module . exports = { networks: { ethereum: { url: "https://eth-mainnet.alchemyapi.io/v2/YOUR-API-KEY" , chainId: 1 }, fenine: { url: "https://rpc.fene.app" , chainId: 89 // Everything else is identical! } } };

EIP-1559 Fee Market Fenine implements dynamic base fee adjustment:
BaseFee n + 1 = BaseFee n × ( 1 + 1 8 × G used − G target G target ) \text{BaseFee}_{n+1} = \text{BaseFee}_n \times \left(1 + \frac{1}{8} \times \frac{G_{\text{used}} - G_{\text{target}}}{G_{\text{target}}}\right) BaseFee n + 1 = BaseFee n × ( 1 + 8 1 × G target G used − G target ) Parameters :Parameter Value Description Gas Target 15M Target gas per block Gas Limit 30M Maximum gas per block Elasticity 2x Max/target ratio Adjustment ±12.5% Max change per block Base Fee Burn 100% All base fees burned
Total Transaction Fee :Fee = ( BaseFee + PriorityFee ) × G used \text{Fee} = (\text{BaseFee} + \text{PriorityFee}) \times G_{\text{used}} Fee = ( BaseFee + PriorityFee ) × G used Where:
BaseFee → Burned (deflationary)
PriorityFee → Validator reward

BaseFee break-even ≈ 67 gwei \text{BaseFee}_{\text{break-even}} \approx 67 \text{ gwei} BaseFee break-even ≈ 67 gwei Comparison :
Ethereum average: 30-50 gwei (deflationary)
Fenine average: 1-5 gwei (inflationary, but low)
Fenine peak: 100+ gwei during congestion (highly deflationary)
