According to bip 143 (https://github.com/bitcoin/bips/blob/master/bip-0143.mediawiki), bitcoin transaction has the information about the input value as part of the witness.
i heard bitcoincash has also a solution for validating the input value (without going through all the blockchain), but i cant find this information in a transaction.
i tried to find it and read about the bch transaction structure and the only thing i found is this proposal: https://github.com/bitcoincashorg/bitcoincash.org/blob/master/spec/replay-protected-sighash.md
and im not sure if its indeed deployed into the bch blockchain.
is there any solution for this problem in bitcoincash?
