Security system and method for using a blockchain service through privacy-aware blockchain arbitration server

A computer-implemented security method for using a blockchain service through a privacy-aware blockchain arbitration server, the method comprising:

• submitting, by an administrator, a configuration block to a privacy-aware blockchain arbitration server;
• defining, within the blockchain configuration block, a typed block which contains at least one block creator constraint and one block approval policy;
• creating a typed block, by a blockchain participant;
• sending the typed block to the blockchain arbitration server;
• determining, by the blockchain arbitration server based on the block creator constraint, which of a plurality of block submitters is approved to submit a block to the blockchain;
• determining, by the approvers, to approve adding a submitted block to the blockchain;
• summing, by the arbitration server, the number of approvals and disapprovals on each block;
• whereby, if the accumulated approvals and disapprovals of blocks satisfy the block approval policy, adding, by the blockchain arbitration server, the block to the blockchain;
• sending, upon receiving a query from the blockchain participants, the queried blocks to the querying participants;
• whereby if the accumulated approvals and disapprovals of blocks don't satisfy the block approval policy, deleting, by the blockchain arbitration server, the block;
• and
• verifying, by the blockchain participants upon receiving blocks from the blockchain arbitration server, whether received blocks satisfy each of the block creator constraint and block approval policy.

A computer-implemented security method for using a blockchain service through a privacy-aware blockchain arbitration server, the method consisting of:

• submitting, by an administrator, a configuration block to a privacy-aware blockchain arbitration server;
• defining, within the blockchain configuration block, a typed block which contains at least one block creator constraint and one block approval policy;
• creating a typed block, by a blockchain participant, the blockchain participant including
• at least one of the following:
• the administrator, a block viewer, a blockchain approver, and a nonparticipant;
• sending the typed block to the blockchain arbitration server;
• determining, by the blockchain arbitration server based on the block creator constraint, which of a plurality of block submitters is approved to submit a block to the blockchain;

• verifying, by the blockchain participants upon receiving blocks from the blockchain arbitration server, whether received blocks satisfy each of the block creator constraint and block approval policy;
• and
• creating, by the blockchain participant, at least one role change creation, a role change creation regulating the roles of the administrator, the blockchain approver, the block viewer, and the nonparticipant.
