A system and method providing Proof of Location or Proof of Location and Velocity consensus in a blockchain network using radio frequency (RF) signals. Nodes validate the location of other nodes in the network using PING-PONG round trip signal propagation time to determine maximum distances to other nodes. These maximum distances are then shared between nodes, whereupon the nodes use computational techniques to resolve validated, geospatial location of the other nodes. The sharing of measured maximum distances to local nodes is a form of Proof of Location consensus. The validated geospatial locations (and velocities) of local nodes are then written to the blockchain, creating a time history for each node. This information may be used by the blockchain operating rules to implement any number of security and other operational functions. The ability of the invention to operate without need for time synchronization between nodes is an advantage of the system.

Methods and systems are presented for providing a framework for facilitating multi-party computation within a sharding environment. After a blockchain is divided into multiple shard chains, a multi-party computation system obtains attributes associated with a first shard chain. The attributes may represent characteristics of the first shard chain, characteristics of transactions recorded in the first shard chain, and characteristics of the computer nodes configured to manage the first shard chain. Based on the attributes, the multi-party computation system determines a multi-party computation scheme that specifies a minimum threshold number of nodes required to participate in a transaction validation process and at least one required node required to participate in the transaction validation process for the first shard chain. The multi-party computation system configures the computer nodes configured to manage the first shard chain to perform the transaction validation process according to the multi-party computation scheme.
