## Brief intro into monero Team's main goal: **Fungibility** --- # Fungibility - Refers to assets that are interchangeable and indistinguisable - Inherently requires financial privacy and security --- # Where it's different from bitcoin - Sender anonimity - Recipient anonimity - Invisible transaction amounts - Effort for uniform game-theoretic consensus (ASIC resistance) --- # This lets us defend against - Price manipulation - Financial surveilence - Supply chain violations - Discrimination - Tainting --- # Short note on ethics - Monero has "great" reputation on darknets - Nor monero core neither MRL support these usecases directly --- # How we achieve? - Sender anonimity - Ring signatures - Recipient anonimity - Stealth addresses - Invisible transaction amounts - Confidential transactions - Near-uniform consensus advantages - CryptNight (and others) --- # Ring signatures - Lets Alice to sign a message (UTXO) on behalf of a passively selected group - Validation only requires that the key was in that group - No further information is required about identity --- # Multilayer Ringsigs (RTRS/StringCT) - New version of Ringsigs break the original transaction to n pieces - every piece is thrown into a different anonimity group... - ...multiple times --- # Confidential transactions - Alice doesn't sign/publish the original amount spent - Commits to a value and proves (zero-knowledge) that it's between 0 and her balance - RingCT is mandatory in the network since 2017 september ---  --- # Stealh addresses - Sender's original address is not contained on the ledger - Unique in every transaction - No to be confused with subaddresses! - Contains a sufficiently large random nonce, impossible to guess the originating pubkey --- # Kovri - Monero's own fork of I2P - Hides identity on a network level (somewhat similar to Tor) - Goal to support a general P2P/Dapp need --- # CryptoNight, Cuckoo Cycle and current research - Hashcash game-theoretically favors miners - Highly vulnerable to centralization - Monero's goal is to make this favorization uniform again - We extensively research candidate algorithms --- - basic strategy is to use a resource that's not scalable in this industry - Memory speed is not - Both CryptoNight and Cuckoo Cycle requires high memory speed - One cannot achieve significant advantage with funds only --- # How can I get in? - MINE AND PARTICIPATE!
