Methods, apparatus, and systems for controlling internet-connected devices having embedded systems with dedicated functions

A method for controlling a plurality of Internet-coupled device nodes (310a, 310b), the method comprising:

• A) conducting first blockchain transactions from a first blockchain wallet having a first address to a second blockchain wallet having a second address, wherein:
• the first blockchain transactions include the second address and at least one first node command and/or at least one first node parameter for at least a first device node (310a) of the plurality of Internet-coupled device nodes;
• the first blockchain transactions are posted to a first blockchain (330a);
• B) conducting second blockchain transactions from the second blockchain wallet to the first blockchain wallet, wherein:
• the second blockchain transactions include the first address and at least one second node command and/or at least one second node parameter for the at least one first device node (310a) or at least one second device node of the plurality of Internet-coupled device nodes;
• and
• the second blockchain transactions are posted to the first blockchain;
• C) transmitting first device node data from the first device node to at least three rendezvous servers using an encryption protocol;
• D) periodically updating a public-private key pair used by the first device node in C) to transmit the first device node data to the at least three rendezvous servers;
• and
• E) querying each of the at least three rendezvous servers for the first device node data;
• F) determining that a majority of the at least three rendezvous servers has the same node data;
• and
• G) uploading a copy of the first device node data to at least one first management server based upon the determination that a majority of the at least three rendezvous servers has the same first node data.
