The rationale behind this suggestion is rooted in the security and verification processes within blockchain technology. By standardizing ECDSA signing, the network aims to enhance consistency and reliability in the validation of transactions, which is a critical aspect of maintaining the integrity of the blockchain.

ECDSA, or Elliptic Curve Digital Signature Algorithm, is widely recognized for its efficiency and robustness in cryptographic operations. Its signatures are relatively small, making them suitable for systems where bandwidth and storage are at a premium. The DER, Distinguished Encoding Rules, format ensures that these signatures are encoded in a universally accepted manner, thus facilitating interoperability among different systems and applications.

Incorporating ECDSA signing into all script types would potentially streamline the transaction verification process by providing a uniform method of proof of work across the network. This could lead to a more secure and simplified framework for participants, reducing the likelihood of errors and inconsistencies.
