Blockchain Sharding and Relay Consensus for Scalability

The patent segments the blockchain network into multiple sharded chains, where each chain operates independently with its own consensus mechanism. This allows parallel processing of transactions across multiple chains, significantly increasing computational speed while maintaining security through the collective strength of all chains. The segmentation principle resolves the contradiction by distributing the computational load across multiple independent units rather than requiring a single complex consensus mechanism to handle all transactions sequentially.

The patent introduces a relay chain as an intermediary that coordinates between multiple sharded chains. The relay chain handles cross-shard communication and finality, allowing individual sharded chains to operate with simpler, faster consensus mechanisms while still achieving global security and consistency through the relay chain's mediation. This intermediary structure enables speed improvement in individual chains without sacrificing overall system security.

By segmenting the network into multiple sharded chains, the system can accommodate a large number of nodes without compromising security. Each shard maintains its own security independently, so adding nodes to one shard does not directly impact the security of other shards. This segmentation allows the system to scale participation horizontally while maintaining reliable security boundaries across all segments.

The patent applies local quality by allowing different security parameters and consensus configurations in different sharded chains based on their specific requirements. Each shard can be optimized for its particular use case while contributing to the overall system security. This local customization enables scalable participation with nodes joining specific shards appropriate to their capabilities and requirements, without forcing a one-size-fits-all security model across the entire network.

The patent divides block validation responsibilities across multiple sharded chains, where each chain validates blocks independently within its own context. This segmentation allows parallel validation operations to occur simultaneously across chains, maintaining high security through distributed validation while achieving fast block creation speeds through parallel processing. The security is preserved because each shard's validation is independent and thorough, while the overall system benefits from the aggregate speed of all shards working concurrently.

The relay chain acts as an intermediary that coordinates block validation across sharded chains. Individual sharded chains can perform rapid local validation without needing to wait for all other chains to complete their validation processes. The relay chain aggregates these validations and ensures global consistency, allowing fast local validation while maintaining overall security through coordinated finality.

The patent uses preliminary action by pre-generating random values (nonces) that are committed in advance before block creation. These pre-committed random values ensure fairness in the selection process, as all participants can verify that the randomness was not manipulated after the fact. At the same time, the committed randomness provides predictability for the selected block maker, allowing the network to know in advance who will create the next block while maintaining the fairness of random selection.

The system incorporates feedback through verifiable random function (VRF) proofs that allow nodes to verify the fairness of the random selection process. The VRF provides cryptographic proof that the random value was generated correctly and not manipulated, giving feedback to the network about the integrity of the selection. This feedback mechanism maintains fairness while providing enough predictability for the selected block maker to prepare and for the network to anticipate the next block creator.
