1. A system, comprising:
a non-transitory memory; and
one or more hardware processors coupled to the non-transitory memory and configured to read instructions from the non-transitory memory to cause the system to perform operations comprising:
monitoring operations of a plurality of computer nodes associated with a shard chain in a plurality of shard chains;
detecting a change of one or more attributes associated with the shard chain based on the monitored operations;
determining, for the shard chain and based on the change of the one or more attributes, a multi-party computation scheme for validating transactions conducted through the shard chain, the multi-party computation scheme specifying a minimum number of computer node requirement for validating the transactions;
determining a key required for performing a transaction validation computation according to the multi-party computation scheme;
decomposing the key into a plurality of shares of the key based on the minimum number of computer node requirement; and
configuring the plurality of computer nodes according to the multi-party computation scheme, wherein the configuring comprises distributing different subsets of the plurality of shares of the key to different computer nodes in the plurality of computer nodes according to a distribution arrangement that enables a first subset of the plurality of computer nodes that meets the minimum number of computer node requirement to re-generate the key based on first shares of the key stored on the first subset of the plurality of computer nodes, and prevents a second subset of the plurality of computer nodes that does not meet the minimum number of computer node requirement from re-generating the key based on second shares of the key stored on the second subset of the plurality of computer nodes.
