Blockchain computer data distribution

A non-transitory computer readable storage medium storing instructions executable by a data processing apparatus and upon such execution cause the data processing apparatus to perform operations comprising:

• determining, by a computing device, that one or more subsequent blocks that are yet to be stored in blockchain include a payload that is not relevant to devices of a particular device type;
• in response to determining that the one or more subsequent blocks that are to be stored in the blockchain include the payload that is not relevant to devices of the particular device type, generating, by the computing device, a checkpoint block that includes checkpoint information that instructs devices of the particular type that access the checkpoint block to perform a blockchain navigation operation before accessing the one or more subsequent blocks;
• and
• storing, by the computing device, the checkpoint block that includes the checkpoint information that instructs devices of the particular type to perform the blockchain navigation operation, ahead of the one or more subsequent blocks in the blockchain.

A system comprising:

• one or more processing devices;
• and
• one or more storage devices storing instructions that are executable by the one or more processing devices to perform operations comprising:
• determining, by a computing device, that one or more subsequent blocks that are yet to be stored in blockchain include a payload that is not relevant to devices of a particular device type;
• in response to determining that the one or more subsequent blocks that are to be stored in the blockchain include the payload that is not relevant to devices of the particular device type, generating, by the computing device, a checkpoint block that includes checkpoint information that instructs devices of the particular type that access the checkpoint block to perform a blockchain navigation operation before accessing the one or more subsequent blocks;
• and
• storing, by the computing device, the checkpoint block that includes the checkpoint information that instructs devices of the particular type to perform the blockchain navigation operation, ahead of the one or more subsequent blocks in the blockchain.
