### Various implementations

- ECDSA
Polkadot SDK provides an [ECDSA](https://en.wikipedia.org/wiki/Elliptic_Curve_Digital_Signature_Algorithm){target=\_blank} signature scheme using the [secp256k1](https://en.bitcoin.it/wiki/Secp256k1){target=\_blank} curve. This is the same cryptographic algorithm used to secure [Bitcoin](https://en.wikipedia.org/wiki/Bitcoin){target=\_blank} and [Ethereum](https://en.wikipedia.org/wiki/Ethereum){target=\_blank}.

- Ed25519
[Ed25519](https://en.wikipedia.org/wiki/EdDSA#Ed25519){target=\_blank} is an EdDSA signature scheme using [Curve25519](https://en.wikipedia.org/wiki/Curve25519){target=\_blank}. It is carefully engineered at several levels of design and implementation to achieve very high speeds without compromising security.

- SR25519
[SR25519](https://research.web3.foundation/Polkadot/security/keys/accounts-more){target=\_blank} is based on the same underlying curve as Ed25519. However, it uses Schnorr signatures instead of the EdDSA scheme.
