Re:Show HN: Gitcoin GR8 audits powered by Ethereum and IPFS on Tuesday December 08, 2020 @08:42AM (#25344865)
Hey everyone, I helped build this.

The website tracks every grant (600+) on Gitcoin and audits all information related to it, especially off-chain data such as description, goals and related information. This gives full transparency to stakeholders while making awesome protocols like Gitcoin more accountable. We snapshot data every 10 minutes. store on IPFS (backed by Filecoin) along with cryptographic proofs on Ethereum (via Matic). The UI allows you to view changes and independently inspect audits.

You can search for any grant and we should have audits that go back to a few days. All new grants are automatically added and we are hoping to make more improvements that will allow end-users to better understand changes to complex information such as the CLR prediction curve, etc. Meanwhile, do let us know what you think about it, suggestions or critiques, on your Discord: https://discord.gg/WkYeZK3hC8

Hey everyone, I helped build this from scratch - happy to answer any questions here.

TL;DR: Using Stripe Identity, Svelte and our Ethereum API gateway, we built an app to generate tamper-proof passes as QR codes which can be easily verified on chain with least privacy implications.

The core tenet of this project is to offer a decentralized alternative to the traditionally accepted opaque process of granting of licenses and permissions, whether in the physical or the digital world. We are starting off with movement passes.

More details on how it works is on our whitepaper: https://www.notion.so/Adabdha-Project-dc221e127c6d4984b916f6...

A live demo is at http://app.adabdha.com.

Hi all, I helped build this and will be happy to answer any questions here.

TL;DR: Using Svelte and our Ethereum API gateway, I built an interactive tutorial to learn and code on blockchain in real time.

Long time HN lurker and an equally long YC reject :) finally breaking the shackles and shipping something on HN. A bit of a personal back story first.

After recovering from a critical health condition due to tampered blood tests and reporting, I started hacking on Ethereum to see if I could leverage the tech to solve this for others. When building a couple of prototypes and eventually my first side project (CryptoVigil) on Ethereum, I realized how painful it was to code on blockchain even for an experienced developer like me. Why wasn't there a Stripe or Twilio for blockchain that I could use to quickly prototype my app with just a few lines of code. With that vision, my co-founder @anomit and I have been working on this since 2 years.

Whether you are a student, a novice in the world of web development or a seasoned fullstack developer, our vision is to make blockchain development accessible to all. The tutorial framework itself will be open sourced once we collect feedback from the community and iron out a few kinks. Anyone can then contribute their lesson plans and spin off their own version if they wish so.

Would love to hear first impressions from fellow developers here. Feel free to break stuff on the interface too!

(It is a developer tool intended for desktop usage. Experience on a mobile browser will be sub-par.)

If you want to dig deeper, check out the docs of the core API. We dog-fooded it to build this very experience!

Re:Navigate tax season using Stripe Atlas on Wednesday January 10, 2018 @10:04AM (#16115357)
Wow, looks like they made it super easy to file franchise taxes. Directly through Atlas and no extra fees either!
Re:International Entrepreneur Rule on Saturday January 14, 2017 @03:11PM (#13400303)
The status is iffy and still no easy path to a permanent residence. They recommend the usual route of O-1A or EB-2 and no adjustment of status either.

Re:Startups that launched at Y Combinator S16 Demo Day 1 on Tuesday August 23, 2016 @12:38AM (#12341439)
Of course not, the cars & their license plates also give it away.
I have a powerful ROG Asus G750JX that I use as my main machine which has dual boot with OSX 10.9 and Windows 10. It was a bit of pain to set it up, haven't gotten the time to update it but it works mostly fine. Even the top end Macbook Pro is no match to the specs I have on this 2.5 year old ROG: 3.2Ghz i7, 32GB RAM, GTX 770M 3GB.

India uses something similar – IMPS. http://www.npci.org.in/aboutimps.aspx
Re:It’s time to explore the Pebble appstore on Monday February 03, 2014 @04:19PM (#7173565)
iOS only for now. Although they did tweet an Android screenshot on Friday. Consistently failing every deadline since Kickstarter days :/ However, kudos to the team, they deserve it for all the hardwork. I'm an early KS backer and they've delivered far beyond my initial expectations. Can't wait to check out 2.0 and appstore!
Re:AngelList Tests Charging For Job Posts on Thursday January 23, 2014 @01:55PM (#7110259)
They've been doing this for a while. I remember seeing this when I tried to post a job back in December.
Aside from the negative effects, at least we will no longer see HTTPS warnings on the web UI due to any non-ssl images being served by the email sender.
Re:Real-time notification mirroring from Android to your computer on Wednesday November 13, 2013 @10:22AM (#6725697)
Nicely done but Krome supports basic encryption. Would really like it if you guys can add that too.

Re:Square Cash on Wednesday October 16, 2013 @03:41AM (#6558484)
A point about spoofed email, Square always seems to ask the sender for a confirmation whether the email was spoofed or not. I tested this by sending it legitimately and through an unauthorized email server.

The only thing that was concerning was when I sent a spoofed email, the receiver was able to know the sender name (cash account name) – "ABC is about to send you cash". Very minor but it allows anyone to find out your name provided they know your email address.

Re:T-Mobile Rocks on Sunday October 13, 2013 @02:15PM (#6543529)
I love T-mobile whenever I am in the US. Coupled with Google Voice and Nexus 4 (LTE works!), I pay way less than an AT&T contract + phone. The only time I was unhappy with their coverage was in my apartment in Mountain View this fall. Apart from that, I've never had to call their customer service. Every time I come back to US, I simply recharge my account online and get going in minutes.

I am curious to try out the Walmart plan (refer comments) next time and cut my costs by half.

Re:Tikker – The wrist watch that counts down your life on Tuesday October 08, 2013 @08:53AM (#6514477)
For Pebble owners, a "watch app" would suffice?
Re:AppSeed – Turn sketches into functioning prototypes fast on Sunday September 22, 2013 @09:45PM (#6428812)
Interesting, so pretty much like POP App[1] except it also does OCR to understand the sketches to speed up the process.

I am seeing this happen with regular searches as well, not always but a few times randomly.

Re:Rackspace Launches Developer Discount on Wednesday September 04, 2013 @06:28AM (#6326606)
Good to hear you guys have finally updated your billing system. We and many others had refused to accept the $24k sponsorship because of the insane requirement.
