zkEVM (Zero-Knowledge Ethereum Sanal Makinesi)
zkEVM'ler, zincir dışı hesaplamaların doğruluğunu doğrulamak için sıfır bilgi kanıtlarını kullanan EVM uyumlu yürütme ortamlarıdır, bu da ölçeklenebilir ve özel Ethereum işlemlerini sağlar.
zkEVM'ler, sıfır bilgi kanıtları oluştururken Ethereum işlemlerini ve akıllı sözleşmeleri yürütmek üzere tasarlanmıştır. Bu kanıtlar, temel verileri ifşa etmeden işlem geçerliliğinin doğrulanmasını sağlar. Bu yaklaşım, hesaplamayı ana Ethereum zincirinden kaldırarak ölçeklenebilirliği önemli ölçüde artırır ve işlem maliyetlerini düşürür. Farklı türdeki zkEVM'ler, mevcut uygulamaların taşınma kolaylığını etkileyen, EVM ile farklı uyumluluk seviyeleri sunar.

Imagine [Ethereum](/tr/terms/ethereum) is a busy city, and a zkEVM is like a super-fast train station built nearby. It processes lots of passenger requests (transactions) really quickly off to the side, and then sends a single, tiny report back to the main city saying everything was done correctly, without slowing down the main city.
🤓 Expert Deep Dive
zkEVMs represent a sophisticated application of zero-knowledge proof technology to enhance blockchain scalability, particularly for Ethereum. The fundamental challenge is bridging the gap between the EVM's execution model and the algebraic structures required by ZK-proof systems (like SNARKs or STARKs). Different zkEVM designs employ distinct strategies to achieve EVM compatibility while enabling ZK-proof generation. Type 1 zkEVMs aim for full EVM equivalence, meaning any valid EVM execution is also a valid zkEVM execution, often requiring complex circuit designs to represent EVM opcodes and state transitions. Type 2 and Type 3 zkEVMs relax strict EVM equivalence for greater ZK-friendliness, potentially sacrificing some compatibility for improved proof efficiency. Type 4 zkEVMs focus on abstracting the computation into a general arithmetic circuit, requiring a transpilation step from EVM bytecode. Key technical considerations include the efficient representation of EVM's Merkle Patricia Trie for state storage, handling of complex opcodes (e.g., hashing, precompiles), and managing the proof generation overhead. The security of a zkEVM relies on the soundness of the underlying ZK-proof system and the correctness of the EVM emulation within the ZK-friendly domain. Trade-offs involve the degree of EVM compatibility versus the efficiency and complexity of proof generation.
