Get signed blocks.
Generates a Pedersen Commitment: *commit = blind * G + value * G2. The commitment is 33 bytes, the blinding factor is 32 bytes.
blind: Sha-256 blind factor type
value: Positive 64-bit integer value
Get SHA-256 blind factor type.
blinds_in: List of SHA-256 blind factor types
non_neg: 32-bit integer value
Gets “range proof” information.
The cli_wallet includes functionality for sending blind transfers in which the values of the input and output amounts are “blinded.”
Note: In the case where a transaction produces two or more outputs, (e.g. an amount to the intended recipient plus “charge” back to the sender), a “range proof” must be supplied to prove that none of the outputs commit to a negative value.
proof: List of proof’s characters
Proves with respect to min_value the range for Pedersen Commitment which has the provided blinding factor and value.
min_value: Positive 64-bit integer value
commit: 33-byte pedersen commitment
commit_blind: Sha-256 blind factor type for the correct digits
nonce: Sha-256 blind factor type for our non-forged signatures
base10_exp: Exponents base 10 in range [-1 ; 18] inclusively
min_bits: 8-bit positive integer, must be in range [0 ; 64] inclusively
actual_value: 64-bit positive integer, must be greater or equal min_value
Verifies that commits + neg_commits + excess == 0.
commits_in: List of 33-byte Pedersen Commitments
neg_commits_in: List of 33-byte Pedersen Commitments
excess: Sum of two list of 33-byte Pedersen Commitments where sums the first set and subtracts the second

Verifies range proof rewind for 33-byte Pedersen Commitment.
nonce: Sha-256 blind refactor type
commit: 33-byte pedersen commitment
