Network for improved verification speed with tamper resistant data

A first node comprising:

• a processor;
• a memory device;
• and
• a computer-readable medium coupled to the processor, the computer-readable medium comprising code executable by the processor for implementing a method comprising:
• receiving, by the first node in a first committee of nodes in a computer network, a request including a node identifier to join a committee by a second node, the first committee managing a first shard of a main blockchain;
• providing, by the first node of the first committee to the second node, a proof of work process, the proof of work process being a function for which the second node provides an input to produce a solution;
• receiving, by first node of the first committee, the solution to the proof of work process from the second node, wherein the second node performs the proof of work process to produce the solution, wherein a plurality of nodes in the first committee verifies the solution;
• generating, by the first node of the first committee, a random string;
• determining, by the first node, a second committee of nodes for the second node using the random string, the second committee managing a second shard of the main blockchain;
• introducing, by the first node to the second committee determined using the random string, the second node, wherein the second committee displaces a node to allow the second node to join the second committee;
• and
• communicating, by the first node, information regarding the second node being in the second committee to other nodes in the computer network by broadcasting an IP address and a second committee identifier of the second node to the other nodes in the computer network,
• wherein the nodes in the first committee have addresses including their IP addresses and a first committee identifier that identifies the first committee of nodes, and the nodes in the second committee have addresses including their IP addresses and the second committee identifier that identifies the second committee of nodes, the first committee identifier and the second committee identifier being different,
• wherein in the method, the first committee of nodes is a leader committee and the nodes in the second committee of nodes are determined by hashing a random value generated by the first committee of nodes and the IP addresses of the nodes in the second committee to form a hashed value, and using a predetermined number of bits of the hashed value, and
• wherein the nodes in the second committee of nodes broadcast their IP addresses and the second committee identifier to the nodes in the first committee of nodes.
