Aleth
Aleth est un client Ethereum C++ et une implémentation de nœud complet. Il fournit un exécuteur de machine virtuelle pour exécuter et déboguer le bytecode, un débogueur d'état de blockchain et une bibliothèque de sérialisation pour encoder et décoder les données en utilisant le format Recursive Length Prefix.
Le projet inclut un outil de minage dédié pour produire des blocs et comparer la performance du matériel de hachage. Il se distingue en outre par un débogueur d'état qui analyse les changements d'état pré- et post-exécution et génère des traces d'exécution étape par étape pour la machine virtuelle.
L'implémentation couvre les opérations de nœud incluant la découverte de pairs via des bootnodes, la synchronisation d'état basée sur des snapshots et la gestion des clés cryptographiques pour signer les transactions. Elle fournit également un framework pour vérifier la stabilité du consensus, simuler la logique des smart contracts et déployer des contrats au sein de réseaux privés.
