Various embodiments relate to a method performed by a processor of a computing system. An example method includes determining a first cryptographic algorithm utilized in a first block of a first blockchain. The first block of the first blockchain has a first unique block identifier. A second cryptographic algorithm utilized in a second block of the first blockchain is determined. The second block of the first blockchain having a second unique block identifier. A first cryptographic algorithm status transition (“CAST”) event is defined if the second cryptographic algorithm is different than the first cryptographic algorithm. A first CAST record is defined upon occurrence of the first CAST event. The first CAST record includes the second cryptographic algorithm and the second unique block identifier. The first CAST record is digitally signed and stored on a second blockchain. The second blockchain may be referenced out-of-band of the first blockchain. Link to Full Patent
