Field-based peer permissions in a blockchain network

A non-transitory machine-readable storage medium, including instructions that when executed by a processor of a multi-tenant server, cause the processor to:

• generate an exchange object for the peer-to-peer blockchain network, wherein the exchange object includes one or more exchange fields and a mapping between each exchange field in the one or more exchange fields and a field of a physical object associated with each peer in the peer-to-peer blockchain network;
• determine a permission for each combination of exchange fields in the one or more exchange fields and peer in the peer-to-peer blockchain network;
• generate, on behalf of a first peer in the peer-to-peer blockchain network, a transaction object based on the exchange object, wherein the transaction object includes a set of field values for the one or more exchange fields and one or more field values in the set of field values are encrypted based on the determined permissions;
• and
• make, on behalf of the first peer, the transaction object available to a second peer in the peer-to-peer blockchain network to attempt to obtain consensus for altering a physical object corresponding to the first peer.

A multi-tenant server to manage data in a peer-to-peer blockchain network, the multi-tenant server comprising:

• a processor;
• a memory storing instruction that when executed by the processor cause the processor to:
• generate an exchange object for the peer-to-peer blockchain network, wherein the exchange object includes one or more exchange fields and a mapping between each exchange field in the one or more exchange fields and a field of a physical object associated with each peer in the peer-to-peer blockchain network;
• determine permissions for each combination of exchange fields in the one or more exchange fields and peer in the peer-to-peer blockchain network;
• generate, on behalf of a first peer in the peer-to-peer blockchain network, a transaction object based on the exchange object, wherein the transaction object includes a set of field values for the one or more exchange fields and one or more field values in the set of field values are encrypted based on the determined permissions;
• and
• make, on behalf of the first peer, the transaction object available to a second peer in the peer-to-peer blockchain network to attempt to obtain consensus for altering a physical object corresponding to the first peer.
