## Which Major Cryptocurrencies Use EdDSA Instead of ECDSA?

While Bitcoin and Ethereum primarily use ECDSA with the secp256k1 curve, several major cryptocurrencies and blockchain platforms have adopted EdDSA, often with the Ed25519 curve. Examples include Cardano, Stellar, Monero, and the Avalanche platform.

These projects often prioritize the improved performance, simpler implementation, and enhanced security properties that EdDSA offers over the older ECDSA standard.

        "caption": "A close-up photograph captures the mirrored surface of a polished optical disc slightly angled atop a finely machined metal spindle assembly, set against an absolute black background creating high contrast and intense reflection. This visual juxtaposition symbolizes the integration of stable physical infrastructure with the inherently volatile digital asset ecosystem, particularly concerning cryptocurrency derivatives. The precision mounting suggests the rigorous algorithmic requirements for decentralized exchange settlement and the critical need for low-latency order book matching in decentralized options protocols. The reflective plane acts as a metaphor for modeling complex payoff structures inherent in customized credit default swaps referencing decentralized finance DeFi collateral pools. Furthermore, the setup evokes concepts related to data partitioning integrity within sharded consensus mechanisms or the precise alignment required for cryptographic key management security across distributed ledger technology nodes. This image speaks to the infrastructural backbone supporting sophisticated financial engineering applied to digital scarcity assets, where slippage control in peer-to-peer swaps hinges on this level of mechanical and digital precision."
