"Private Transactions" TAG

Following the publication of an in-depth research report concerning the field of Zero-Knowledge Proofs (ZKPs), Smith + Crown has been keenly tracking research breakthroughs and major implementation releases related to these proof systems in their application to scaling and privacy issues that have hereto troubled base layer blockchain networks. As previously discussed, ZKPs provide the ability to succinctly...

AZTEC uses a UTXO model similar to Bitcoin’s. AZTEC uses ‘notes’ instead of balances, with notes encrypting a number representing a value (i.e. a number of ERC-20 tokens). Notes have owners, with ownership defined by an Ethereum address, and the owner must provide a valid ECSDA signature for the note to be spent: the protocol’s...

MimbleWimble’s privacy-focused design, which hides amounts transacted and where addresses do not exist, can appear unintuitive to those more accustomed to either Bitcoin’s UTXO model or Ethereum’s accounts-based approach. Cryptoassets built on the MimbleWimble protocol, such as both Grin and BEAM, enjoy several privacy features, most notably the obfuscation of amounts being transacted and the...
