1. A system, comprising:
a microprocessor; and
a computer readable medium, coupled with the microprocessor and comprising microprocessor readable and executable instructions that, when executed by the microprocessor, cause the microprocessor to:
generate a first transaction block in a first blockchain,
wherein the first transaction block in the first blockchain comprises a first token that points to first blockchain data and a first table identifier that identifies a first tokenization table where the first blockchain data associated with the first blockchain is provided;
generate a first transaction block in a second blockchain,
wherein the first transaction block in the second blockchain comprises a first token that points to first blockchain data and the first table identifier that identifies the first tokenization table where the first blockchain data associated with the second blockchain is provided and a second token that points to second blockchain data and a second table identifier that identifies a second tokenization table where the second blockchain data associated with the second blockchain is provided;
detect a first event, wherein the first event is to forget the first blockchain data associated with the first blockchain in the first tokenization table; and
in response to detecting the first event, forget the first blockchain data associated with the first blockchain in the first tokenization table,
wherein the first blockchain data associated with the first blockchain in the first tokenization table is covered by a tokenization hash in the first transaction block associated with the first blockchain, and
wherein the first tokenization table is different than the second tokenization table.
