Wallet serialization blocks update to secp256k1 0.24.0 #2282

Open tmpolaczyk opened 2 years ago

After updating to secp256k1 0.24.0, the wallet does not allow to unlock previously created wallets with this error:

[2022-10-17T15:37:24Z ERROR witnet_wallet::actors::app::error] Internal Error: repository failed: database failed: bincode failed: io error: unexpected end of file

We need to find out why is that happening, and implement some workaround to allow us to update to secp256k1 0.24.0 or greater.

This seems to be because of the ExtendedSK type, it is used to store the master key, and the derived internal and external keys.

See the master_key and account_key functions here: https://github.com/witnet/witnet-rust/blob/8304d479a1d78ad6b3266af30d468004384086ac/wallet/src/repository/keys.rs
