An almost 50% reduction in public key size can be realized without changing any fundamentals by dropping the Y coordinate.
Bitcoin How do private and public keys work?
This created considerable difficulty in backing up one’s keys, considering backups have to be run manually to save the newly-generated private keys. If a new key pair set is generated, used, and then lost prior to a backup, the stored satoshis are likely lost forever. Many older-style mobile wallets followed a similar format, but only generated a new private key upon user demand. Wallet programs create public keys to receive satoshis and use the corresponding private keys to spend those satoshis. Wallet files store private keys and (optionally) other information related to transactions for the wallet program. Your private key is a unique secret code validating wallet ownership and facilitating transactions.
