1. A computing device of a decentralized network comprising:
a network interface configured to couple the computing device to the decentralized network;
a hardware processor; and
a non-transitory computer readable storage medium storing program instructions for execution by the hardware processor in order to cause the computing device to:
transmit a request for a value associated with a key, wherein a hash of the value is stored in a first adaptive radix trie (ART) associated with a first block in a fork in a blockchain, and wherein the first block is an ancestor of a current block in the fork in the blockchain;
transmit a second request for a proof that the hash of the value received in response to transmission of the request is valid;
determine an ART root hash of the first block using a head shunt proof and a first segment proof received in response to transmission of the second request, wherein the head shunt proof is based on a hash of data derived from a second ART different than the first ART that is associated with a second block in the fork in the blockchain that precedes the first block, wherein the second block is another ancestor of the current block in the fork in the blockchain;
determine a second ART root hash of the current block using a second shunt proof received in response to transmission of the second request, a second segment proof received in response to transmission of the second request, and the determined ART root hash of the first block;
compare the determined second ART root hash of the current block to a third ART root hash provided by a second computing device; and
validate that a third ART associated with the current block represents an accurate digest of a materialized view of the fork in response to a determination that the determined second ART root hash matches the third ART root hash.
