Products that do what fallback() – write web apps in Solidity and serve HTTP over Ethereum does
Hi HN! I recently open-sourced a project I’ve been working on over my winter break: a Solidity web framework you can use to write web apps in Solidity (and more generally, a proof-of-concept implementation of an arbitrary network protocol over Ethereum). Here’s a demo web app on the Optimism Goerli testnet: http://simple.fallback.natecation.xyz/ Running this Solidity code: https://github.com/nathanhleung/fallback/blob/main/src/examp... There’s a lightweight TCP server script that’s listening on the demo app domain that forwards requests…

Hey HN! My name's Nadav Hollander, and I'm the Founder of Dharma. Dharma is building an open-source library that makes it really easy to programatically borrow and lend cryptocurrencies using smart contracts on the Ethereum blockchain. Today we're launching our Alpha Testnet release -- a command line tool that allows you to 1. Access a line of cryptocurrency credit from the command line in under 5 minutes 2. Easily build a bot that auto-invests in loans under hyper-customizable, programmable criteria Check it out: https://github.com/dharmaprotocol/dharma-cli Why I Think…

Hi All, I released an EVM/Solidity decompiler recently, here: http://www.eveem.org/ Since it uses symbolic execution underneath, the results are quite awesome. There is also an api that delivers a .json / middle language representation of every contract here: http://eveem.org/code/{{address}}.json The plan is to open-source it as soon as I clean up the code a bit. Spent the last two month crunch-time to get it delivered from scratch :)

Hi guys, I've written the first proof-of-mistake crypto token on top of Ethereum. You can see it at http://www.lostethereum.com/ It's basically a proof-of-burn substitute for users who mistakenly sent to the wrong address. It requires a web3 enabled browser, i.e chome with MetaMask, Parity, Mist, etc. This let's the web interface seamlessly interact with the Ethereum network. Let me know what you guys think.

I built this over the weekend. Any feedback is appreciated. Please note you will need a WebGL enabled browser. Thank you for checking it out. --UPDATE-- HN Traffic is strangling earthbit. There is sporadic downtime due to the web services I am using, if no transactions appear after a few seconds, then please try again in an hour.

Hi! I’ve always wanted a simple way to throw my Python projects online. Just to try things out, share them, or test a webhook with a real endpoint. But every time I hit the same wall: Buy a server, Set up HTTPS, Configure DNS, Get a domain. Write boilerplate to glue it together. It always felt like too much for something so small that I wanted to test. So Ive been hacking on Thread4 (currently in alpha): a tiny platform where you can write a Python function and go live instantly at yourname.thread4.eu. It’s not for production use, just quick testing, experimenting, or sharing your idea…

Please check out out project, Lite Engine[1], a Backend as a Service web application platform. We provide everything you need to rapidly prototype and deploy your single page applications: static file hosting for your html, css, javascript and other assets, a subdomain on our site, security with https, and a 'create your own API' with SQL over CORS and JSON. I think of this as "geocities with a CORS backend". For your backend we've developed a system we call API Queries. You'll define SQL queries, save them on the backend, then execute them with http post requests that return JSON responses.…

Hi guys, It is no secret that I'm pretty tired of the political infighting around Bitcoin. The environment got so toxic that I stopped most of my Bitcoin-centric development to focus on other projects. I'm pretty sure there are many developers who have felt the same way, and the result has been an explosion in alternative coins and technologies as developer resources have gone elsewhere. So, I started a simple experiment. What if we got rid of developers entirely, and just replicated and adapted the deflationary structure of Bitcoin on Ethereum. We could model the entire process as an…

Hi HN, I'm the creator of epress. After a lot of work, I'm excited (and a bit nervous) to finally share it with you. For years, I've been feeling like a digital tenant on the platforms I use every day. My content, my social graph, my online identity—they were all stored on someone else's servers, subject to their rules, algorithms, and business models. I could be de-platformed, my data could be sold, or an API I relied on could suddenly be put behind a paywall. I looked into existing decentralized alternatives. While many are great projects, I found they often shifted the trust from a big…

If we want better web3 experiences, developers need better tools. RPC nodes are really good at executing transactions, however they are notoriously cumbersome to set up, and reading large chunks of data is not very efficient: To show a list of transactions and receipts, nodes have to re-execute smart contract code on entire blocks. For every read call. Not great at scale. Which is why everyone is building ETLs to move data from the chain into their own database. This GraphQL API is our first step in allowing developers to spend more time on building product, rather than ETL infrastructure.

This is a model I’ve been thinking about lately. It demonstrates a pattern that I’m wondering could exist, where terminal applications, BBS-style shared user boards, and other expressions of creativity and sharing are created with web technologies but rendered into the terminal and accessed over SSH. I like that this brings back some kind of old days of the internet feeling and uses web technologies but sidesteps the public World Wide Web, even though it’s still on the internet. You can try it out too right now, and I’m thinking about making the self-hosting specialized applications part a…

I'd like to share a project I've been working on for the past few months. It's a distributed workflow engine written entirely in Go. Some highlights: * Tasks are executed in a Docker container * Can run stand-alone or distributed * Highly extensible * Able to enforce limits (CPU/RAM) per task * Web UI Would love the get your feedback on it, and find out if this could be useful.

Hi HN, While building RAG agents, I noticed a lot of token budget was wasted on formatting overhead (HTML tags, JSON structure, whitespace). Existing solutions felt too heavy (often requiring torch/transformers), so I wrote this lightweight, zero-dependency library to solve it. It includes strategies for context packing, PII redaction, and tool output compression. Benchmarks show it can save ~15% of tokens with negligible latency overhead (<0.5ms). Happy to answer any questions!

Hi HN, I’m one of the devs behind StarDesk, a P2P-first remote desktop we’ve been building for ~1 year. We started this partly out of frustration: some popular RDP tools haven’t seen meaningful updates in a long time, and long-standing issues are often left unaddressed. As devs, we really dislike software that stagnates once it “works well enough”. StarDesk is our attempt to do it differently. What we focus on: -P2P by default (relay as fallback) -Low RTT + low jitter > chasing max bitrate -Encoder / input path tuned for real-time interaction -Modern E2EE (TLS/DTLS) UX-wise, setup…

Hey everyone, we built a local-first, open-source framework to allows you to export and build applications with your personal data. This August, we built a digital footprint exporter (https://news.ycombinator.com/item?id=41325719) that allowed people to get back their personal data, but there was no way to interact with it. So we added a python package, improved the reliability of the exporting, and implemented a unified JSON structure across platforms. How it works: - Electron’s built-in webview element is used to navigate to the platform’s website and the user can connect…
