<p>Under the hood, Monero is a powerhouse of technology and code. Work on the code base is very versatile: it concerns maintaining the current code, fixing bugs, implementing new innovations, etc. It is easy to get lost in all the developments of the past six months, but we’ll take a look at a few major development highlights, and what we may expect for the upcoming October protocol upgrade.</p> <p>Under the hood, Monero is a powerhouse of technology and code.

<p>On March 9, 2019, Monero had its scheduled upgrade on block 1788000. The scheduled network upgrade introduced four major changes. First, the dynamic block size algorithm was adjusted to better accommodate short-term spending sprees while keeping long-term growth sensible. Second, a PoW tweak (CryptoNight-R) curbed the ASICs previously present on the network.</p> <p>On March 9, 2019, Monero had its scheduled upgrade on block 1788000.

Second, a PoW tweak (CryptoNight-R) curbed the ASICs previously present on the network. Third, an encrypted payment ID was added to each transaction to improve transaction homogeneity. Fourth, the development team simplified amount commitments by shrinking the size of amount encodings and using deterministic masks. These changes made transactions smaller and were deemed safe to apply by the Monero Research Lab. Since the update, several major focus areas have received attention.</p>

<p>The starting screens/startup wizards were rebuilt from scratch, with the most notable change being the inclusion of simple mode. This new startup option was created to get new users up and going as quickly as possible by utilizing a simplified UI and connecting to a remote node by default The GUI also saw new screens, such as a merchant page, which allows the GUI to be used as a point-of-sale system, as well as support for multiple accounts (made possible by subaddresses).</p> <p>The starting screens/startup wizards were rebuilt from scratch, with the most notable change being the inclusion of simple mode.

<p>Another major success was the added ability for users to utilize the GUI with their Trezor hardware wallets. The last major inclusion is the new white theme designed by knufflebund.

<p>Back in January 2019, Monero Research Lab and several developers attended the Stanford Blockchain Conference. This conference explores the use of formal methods, empirical analysis, and risk modeling to better understand security and systemic risk in blockchain protocols. The same month they’ve discovered patterns in Monero nonces, due to varying search strategies employed by different miners.</p> <p>Back in January 2019, Monero Research Lab and several developers attended the Stanford Blockchain Conference.

<p>A lot of discussion took place around deprecating or eliminating Payment IDs, due to privacy impacts and confusing UX. After much discussion, wallets hid this feature for the April update, and most wallets will completely remove the feature in the October update. Exchanges, payment processors, and other services should upgrade to support Monero subaddresses as soon as possible, which offer greater privacy and a better user experience.</p> <p>A lot of discussion took place around deprecating or eliminating Payment IDs, due to privacy impacts and confusing UX.

<p>A lot of work has been performed by the Research Lab team in researching several new ring signature alternatives. These schemes include the likes of: <a href="https://eprint.iacr.org/2019/550" target="_blank">Spartan</a>, <a href="https://eprint.iacr.org/2019/508" target="_blank">RingCT3.0</a>, and <a href="https://lelantus.io/lelantus.pdf" target="_blank">Lelantus</a>. They have shared an analysis of Lelantus, including prototype code for Monero-to-Lelantus output migration, and plan on reviewing <a href="https://eprint.iacr.org/2019/580.pdf" target="_blank">Omniring</a> next, which would massively improve Monero’s privacy.</p> <p>A lot of work has been performed by the Research Lab team in researching several new ring signature alternatives.

<p>In addition to these reviews from external sources, MRL has been working up schemes of their own, which include the likes of <a href="https://eprint.iacr.org/2019/595" target="_blank">DLSAG</a> and CLSAG. DLSAG would enable non-interactive refund transactions for interoperable payment channels which would, in turn, enable second-layer solutions on Monero such as Lightning Network and atomic swaps. CLSAG (compact linkable spontaneous anonymous group) is a similar ring signature scheme to what is presently used, but is ~25% smaller and ~20% faster to verify transactions, all as a low-impact change.</p> <p>In addition to these reviews from external sources, MRL has been working up schemes of their own, which include the likes of <a href="https://eprint.iacr.org/2019/595" target="_blank">DLSAG</a> and CLSAG.

<p>In December, a video program “Breaking Monero” was introduced. It helps newbies to understand how the weaknesses and flaws of Monero. While this might seem like a strange goal on the surface, it’s important to remember that only by highlighting and discussing these flaws can we hope to overcome them, both technologically and as a community. So far, the topics covered include: a ring signatures introduction, 0-decoy and chain reactions, chain splits (key image reuse attack), input selection algorithm, unusual ringsize, remote nodes, timing attacks, poisoned outputs (EAE attack), public mining pools, input/output metadata, and blockchain explorer opsec. These are also available for viewing on the Monero Community Workgroup YouTube channel.
