3.0.ipv8.attestation.identity.database.to_list(obj: Any | None) → list: If no results are found in the database, the cursor will return None. This function always returns a list.

class 3.0.ipv8.attestation.identity.database.IdentityDatabase(file_path: str)

Bases: 3.0.ipv8.database.Database

Database to store identity layer data.

This database stores: meta information of different pseudonyms, both ours and those of others. This database does not store: commitments and schemes for proving knowledge of data.

LATEST_DB_VERSION = 1

insert_token(public_key: 3.0.ipv8.types.PublicKey, token: 3.0.ipv8.attestation.tokentree.token.Token) → None: Inject a Token belonging to a certain public key into this database.

insert_metadata(public_key: 3.0.ipv8.types.PublicKey, metadata: 3.0.ipv8.attestation.identity.metadata.Metadata) → None: Inject Metadata belonging to a certain public key into this database.

insert_attestation(public_key: 3.0.ipv8.types.PublicKey, authority_key: 3.0.ipv8.types.PublicKey, attestation: 3.0.ipv8.attestation.identity.attestation.Attestation) → None: Inject an Attestation made by some authority for a certain public key into this database.

get_tokens_for(public_key: 3.0.ipv8.types.PublicKey) → set[3.0.ipv8.attestation.tokentree.token.Token]: Get all tokens in the tree of a certain public key.

get_attestations_by(public_key: 3.0.ipv8.types.PublicKey) → set[3.0.ipv8.attestation.identity.attestation.Attestation]

Get all attestations made by a certain public key (for others).

This is the signing authority.
