Provided is a process that includes: obtaining a first request by a first program associated with a first sub-partition of a first partition of a tamper-evident data store of a decentralized computing platform to read data stored in either (i) a second sub-partition of the first partition of the tamper-evident data store of the decentralized computing platform, or (ii) a second partition of the tamper-evident data store of the decentralized computing platform; determining with a subset of peer computing nodes of a set of peer computing nodes that the first program is authorized to read from the second sub-partition or the second partition; and in response to the determination, causing the requested data to be read from the second sub-partition or the second partition.
