Systems and methods for creating a consistent blockchain including block commitment determinations are disclosed herein. An example method includes receiving a request for blockchain data from an application or a user, receiving proposed canonical heads from a plurality of blockchain nodes, receiving votes to determine a correct state for a consistent blockchain that includes a canonical head, the blockchain data being included in the consistent view of a blockchain, determining the canonical head based on the votes, determining a commitment level for at least one block in the consistent view of the blockchain, providing the consistent view of the blockchain to the application or the user, and exposing the commitment level for the at least one block.

Systems and methods for improving reliability in blockchain networks using sharding are disclosed herein. An example method includes assigning a unique identifier to a user, applying a deterministic function, such as a consistent hashing algorithm, to the unique identifier to select a unique set of nodes that are assigned to a shard for the user, wherein the nodes are a subset of available nodes, receiving a request for blockchain data from the user, generating a response to the request using a consistent view of a blockchain obtained from the unique set of nodes, and transmitting the response to the request to the user.

Systems and methods for improving reliability in blockchain networks using sharding

Systems and methods for rate limiting API service requests at an API service platform. An example method includes receiving a plurality of client service requests, determining when a safe operating threshold has been exceeded by the received requests to create a system overage or debt. In the case where it is determined that the safe operating threshold has been exceeded, determining the degree to which the safe operating limit has been exceeded, and rate limiting one or more clients transmitting service requests, identified as having the highest service request rates to eliminate the overage or debt.
