Zincirler Arası İletişim (Cross-Chain Communication)
Farklı bağımsız blokzinciri ağlarının veri, token veya mesaj alışverişi yapmasını sağlayan protokoller ve teknolojiler.
Temel protokoller: token köprüleri (Wormhole), genel mesajlaşma (LayerZero, Axelar, CCIP), yerel birlikte çalışabilirlik (IBC, XCM), atomik swaplar (HTLC).

[Bitcoin](/tr/terms/bitcoin) ve [Ethereum](/tr/terms/ethereum)'un farklı diller konuşan iki ada olduğunu hayal et. Zincirler arası iletişim, adalar arasında gidip gelen bir çevirmen gemisi gibidir; mesajları ve paketleri taşır ve hiçbir adanın aldatılmamasını sağlar.
🤓 Expert Deep Dive
Köprü mimarileri: Lock-and-Mint (honeypot riski), likidite köprüleri (sermaye verimsizliği), mesaj iletimi (LayerZero, CCIP), IBC (light client ile güvensiz). En büyük hackler: Ronin ($625M), Wormhole ($320M), Nomad ($190M).
❓ Sık sorulan sorular
Why are cross-chain bridges so often hacked?
Bridges are high-value targets because they hold large amounts of locked assets. The most common attack vectors are: compromised validator keys (Ronin Bridge), smart contract bugs (Wormhole), and economic exploits on governance logic (Beanstalk). Trusted bridges with small validator sets are especially vulnerable.
What is the difference between a bridge and IBC?
A traditional bridge relies on external validators (a trusted third party) to attest that an event happened on the source chain. IBC (Inter-Blockchain Communication) uses on-chain light clients to cryptographically verify the source chain's state directly, requiring no trusted intermediary.
What is an atomic swap?
An atomic swap is a trustless exchange of tokens between two different blockchains using Hash Time-Locked Contracts (HTLCs). It either completes in full (both parties get their tokens) or fails completely (both get their tokens back). No bridge or intermediary needed, but both chains must support the same hash function.
