NETWORK ARCHITECTURES

Blockchain Infrastructure & Networks

Analyse comparative de l'écosystème financier décentralisé et institutionnel. Explorez les blockchains publiques (Permissionless) et les réseaux de consortium (Permissioned) qui redéfinissent l'infrastructure des marchés de capitaux.

Section A

Public L1 Architectures

Bitcoin

La couche de règlement suprême. Privilégie la sécurité et la certitude absolue de finalité (~60 min) au détriment de la vitesse de la chaine de base. La mise à l'échelle s'effectue hors-chaine via le Lightning Network (L2).

Consensus Proof of Work
Throughput (L1) ~7 TPS
Tokenomics 21M Cap / Deflationary
Use Case Store of Value
Deep-Dive Architecture
Whitepaper Explorer

Ethereum

L'ordinateur mondial décentralisé (PoS). Son architecture "Rollup-Centric" délègue désormais l'exécution des contrats intelligents à de multiples Layer 2 (Arbitrum, Optimism) pour absorber massivement le trafic DeFi.

Consensus Proof of Stake
Throughput (L1) ~15-30 TPS
Tokenomics EIP-1559 Burn
Use Case Smart Contracts (DeFi)
Deep-Dive Architecture
Whitepaper Etherscan

Solana

La machine à états haute fréquence. Conçue pour une latence d'exécution minimale via son asynchronisme (PoH). Opère structurellement à la limite matérielle des serveurs d'entreprise (Outages historiques).

Consensus PoH + PoS
Throughput (Real) ~3,000-4,000 TPS
Tokenomics Inflationary Schedule
Use Case High-Speed dApps / Trading
Deep-Dive Architecture
Whitepaper Solscan

BNB Chain

L'écosystème institutionnel de Binance. Un fork Ethereum qui sacrifie structurellement la décentralisation (Restreint à 21 validateurs stricts) au profit d'un trafic transactionnel retail massif (TVL).

Consensus PoSA (21 Vals)
Throughput (L1) ~100+ TPS
Tokenomics Auto-Burn System
Use Case Retail DeFi / Gaming
Deep-Dive Architecture
Whitepaper BscScan
Section B

Institutional & Permissioned Networks

Executive Summary : While public blockchains prioritize openness and censorship resistance, institutional networks focus on regulatory compliance, privacy, and capital markets infrastructure integration.

SWIAT

Infrastructure bancaire privée orientée Tokenisation d'actifs, Settlement institutionnel et conformité réglementaire Européenne/Suisse.

Network Type Permissioned Blockchain
Governance Consortium-driven
Monetary Model No Native Token
Use Case Digital Securities / Funds
Deep-Dive Architecture & Risk

Canton Network

Réseau institutionnel interconnecté basé sur les smart contracts Daml, visant la création d'une infrastructure de marché financier interopérable.

Network Type Interoperable Privacy Net
Smart Contracts DAML
Monetary Model No Native Token
Use Case Repo Markets / Bonds
Deep-Dive Architecture & Risk
Section C

Digital Money & Settlement Layers

Executive Summary : Les Stablecoins (USDT, USDC) ne sont pas de simples "cryptos", mais une infrastructure de règlement mondiale (Liquidity Bridge Layer) opérant au-dessus des couches publiques, essentielle pour les flux institutionnels transfrontaliers (Off-CBDC).

Stablecoin Infrastructure (USDT vs USDC)

Analyse structurelle des principales monnaies numériques privées fiat-backed. Architecture, modélisation des risques (Depeg, Liquidity Run) et mécaniques de flux (Mint, Burn, Yield).

Category Fiat-Backed Digital IOUs
Key Players Tether (USDT), Circle (USDC)
Systemic Role Global Liquidity Routing
Governance Centralized Issuer

Cartographie de la Hiérarchie Monétaire

Le système financier numérique ne se limite pas aux blockchains publiques. Il se structure en couches superposées (Layering), de la monnaie de banque centrale visant à garantir le règlement final, jusqu'aux actifs symbolisés (DLT) gérés par notre Risk Engine.
