mrl4_abstract: We identify several blockchain analysis attacks available to degrade the untraceability of the CryptoNote 2.0 protocol. We analyze possible solutions, discuss the relative merits and drawbacks to those solutions, and recommend improvements to the Monero protocol that will hopefully provide long-term resistance of the cryptocurrency against blockchain analysis. Our recommended improvements to Monero include a protocol-level network-wide minimum mix-in policy of n = 2 foreign outputs per ring signature, a protocol-level increase of this value to n = 4 after two years, and a wallet-level default value of n = 4 in the interim. We also recommend a torrent-style method of sending Monero output. We also discuss a non-uniform, age-dependent mix-in selection method to mitigate the other forms of blockchain analysis identified herein, but we make no formal recommendations on implementation for a variety of reasons. The ramifications following these improvements are also discussed in some detail. This research bulletin has not undergone peer review, and reflects only the results of internal investigation.
mrl5: Ring Signature Confidential Transactions
mrl5_abstract: This article introduces a method of hiding transaction amounts in the strongly decentralized anonymous cryptocurrency Monero. Similar to Bitcoin, Monero is a cryptocurrency which is distributed through a proof of work “mining” process. The original Monero protocol was based on CryptoNote, which uses ring signatures and one-time keys to hide the destination and origin of transactions. Recently the technique of using a commitment scheme to hide the amount of a transaction has been discussed and implemented by Bitcoin Core Developer Gregory Maxwell. In this article, a new type of ring signature, A Multi-layered Linkable Spontaneous Anonymous Group signature is described which allows for hidden amounts, origins and destinations of transactions with reasonable efficiency and verifiable, trustless coin generation. Some extensions of the protocol are provided, such as Aggregate Schnorr Range Proofs, and Ring Multisignature. The author would like to note that early drafts of this were publicized in the Monero Community and on the bitcoin research irc channel. Blockchain hashed drafts are available in [14] showing that this work was started in Summer 2015, and completed in early October 2015. An eprint is also available at http://eprint.iacr.org/2015/1098.
mrl6: Subadresses
mrl6: An Efficient Implementation of Monero Subadresses
mrl6_abstract: Users of the Monero cryptocurrency who wish to reuse wallet addresses in an unlinkable way must maintain separate wallets, which necessitates scanning incoming transactions for each one. We document a new address scheme that allows a user to maintain a single master wallet address and generate an arbitary number of unlinkable subaddresses. Each transaction needs to be scanned only once to determine if it is destinated for any of the user’s subaddresses. The scheme additionally supports multiple outputs to other subaddresses, and is as efficient as traditional wallet transactions.
mrl7: Sets of Spend Outputs
mrl7_abstract: This technical note generalizes the concept of spend outputs using basic set theory. The definition captures a variety of earlier work on identifying such outputs. We quantify the effects of this analysis on the Monero blockchain and give a brief overview of mitigations.
