1. A method for moderation in a permissioned blockchain using a hash-oriented scheme, comprising:
generating, by a processing device of a processing server, a first hash value by hashing a first reference value;
generating, by the processing device of the processing server, a block proof including at least the first hash value, a second hash value, a third reference value, and a block value;
verifying, by the processing device of the processing server, a block header included in a most recent block of a blockchain using the block proof;
receiving, by a receiver of the processing server, a new block value;
generating, by the processing device of the processing server, a new block header including at least the first reference value, a second reference value, a fourth reference value, and the new block value;
generating, by the processing device of the processing server, a new block for the blockchain including the new block header and one or more transaction data values; and
transmitting, by a transmitter of the processing server, the new block to one or more additional nodes associated with the blockchain.
