In this work, we propose a stateless blockchain called CompactChain, which
compacts the entire state of the UTXO (Unspent Transaction Output) based
blockchain systems into two RSA accumulators. The first accumulator is called
Transaction Output (TXO) commitment which represents the TXO set. The second
one is called Spent Transaction Output (STXO) commitment which represents the
STXO set. In this work, we discuss three algorithms - (i) To update the TXO and
STXO commitments by the miner. The miner also provides …
