"A blockchain is a distributed database that maintains a continuously-growing list of data records hardened against tampering and revision... The blockchain is seen as the main technical innovation of bitcoin, where it serves as the public ledger of all bitcoin transactions." (Source: Wikipedia)

In a similar manner, the IP blockchain is also a distributed database that maintains a continuously-growing list of IP records sharing Bitcoin blockchain features such as non-repudiation, confidentiality, availability and integrity. The IP Blockchain serves as the public ledger for all forms of IP registration.
