+# What
+
+Part time Monero coding for 3 months. Have a couple of distinct things i want to address and start working on first:
+
+1. Decentralized remote node scanning/selection for both CLI and GUI wallets  
+Provide an easy to use option for Monero remote node users. A feature to sync the wallet and send transactions without relying on any centralized service or specific remote node.
+
+2. Improving GUI requests processing to prevent GUI unresponsiveness and lagging.  
+Improve communication between GUI wallet and the daemon, hardware wallets.  
+Is an important issue that affects UX and overall product quality.
+
+3. Additionally will be working on the GUI and CLI code, submitting bug fixes and addressing the ongoing issues, putting my efforts where it is appropriate
+
+# Who
+
+I'm Xiphon, pretty familiar and contributed to Monero core and GUI codebase, helped to implement subaddress support and other missing parts in CCS backend.

+# Proposal
+
+10 hours per week at 55 USD/hour rate for a total of 111 XMR. XMR/USD rate is based on the 14-day moving average exponential on Kraken from 5 April 2019, which is approximately 59.36 XMR/USD.
+
+## Decentralized remote node scanning/selection for both CLI and GUI wallets  
+
+As a part of this approach I've implemented `--public-node` (already merged) mode. Once it is enabled user's daemon starts to advertise its public RPC port to others through P2P.  
+And also committed `--no-sync` cli switch that optionally prevents a daemon from downloading the blockchain.
+
+Regarding the proposal I plan to introduce `--bootstrap-daemon auto` mode that will lookup for available public nodes (collect the list over P2P) and then proxify (utilizing current `--bootstrap-daemon` implementation) any incoming RPC request to automatically selected remote node.
+
+Both used in conjunction `--no-sync --bootstrap-daemon auto` on the wallet side and having enough volunteers running their nodes in `--public-node` mode will achieve the specified goal (CLI wallet).
+
+Finally, I will integrate it into GUI wallet to enhance the Simple Mode.
+
+## Improving communication between local daemon and GUI wallet
+
+Current GUI wallet lags and UI becomes unresponsive for quite a noticeable and annoying time during wallet operations. Hardware wallet communications (Ledger/Trezor) freeze the UI as well.
+
+Will locate the code parts that block the UI in order to implement background and/or kind of async requests processing. Might involve some related optimizations and speedups.
