Hi HN,I built a simple tool to solve a problem I've faced as a developer and freelancer: how can you definitively prove a file (like code, a contract, or a design) existed at a specific time?It's called Akashi Notari, and it’s a simple utility for creating an on-chain "Proof of Existence." It lets you anchor any file's cryptographic hash on the blockchain (supports Base, Ethereum, Optimism)....
In this post I brainstorm ideas to solve the sibyl attack problem. I believe bringing together location-proof service (FOAM - https://foam.space/), staking and face recognition algorithms can solve the problem.
Will be happy to hear your thoughts and critique!

This is the third post. Here I try to imagine the ideal system. What the project might look like in the case of it's success? What if all social connections in the world are replicated? Who may benefit from a database like this?
Will be happy to hear your thoughts and critique!

As I already mentioned in hackernews (https://news.ycombinator.com/item?id=18988497) I'm writing a series of posts, which I'll then transform into whitepaper.
This is the second post. It proves the six degrees of separation idea. It turns out Microsoft, Facebook and Neil deGrasse Tyson all agree that the world is connected in less than 7 handshakes. There is also some simple math, confirming that the idea works, and my further plan.
The post is for non-technical readers.
Will be happy to hear your thoughts and critique!
I would like anybody to be able to do the same. Or maybe invent other use cases. Here is the source code: https://github.com/porobov/million-ether-homepage-2-contract.... It is well documented and can be used for education (smart contract upgradeability, oracles, ERC-721 token, web3).
The project is called The Million Ether Homepage. It is like the well-known Million Dollar Homepage but with some blockchain-powered cool features: - buy pixels and own them for life (or for as long as Ethereum is available) - sell or rent pixels out with no commission - put ads to the pixels you own and replace it anytime - trade pixels through 3rd party decentralized exchanges (ERC721 token standard implemented). - the price for a 10x10 pixels block starts with $1 and doubles every 10% sold.
The first version was launched back in 2016. It collected $11k for charity. This version also sends 80% of income to charity.
It is at Minimal Viable Product stage and a bit clumsy. You'll need Metamask extension for your browser and some ether.
Would love to hear your thoughts.
I have a vision, but I don't know how to get there yet. So I decided to start showing my thoughts online. I'm writing a series of posts, which I'll then transform into whitepaper. This way I hope to learn best (by explaining) and maybe get some help in brainstorming.
This is my first post. It is about personal motivation. In short: "My mission is to move the world towards peace and I believe it is possible by uniting the whole world in six handshakes".
If you have any project that come to your mind or any people involved in a project like this, or other interesting bits of information please let me know. I would be very happy to hear from you.
I've tried it several times and want to do it more. I fasted for 2 days max. It is like hangover upside down. You feel terrible for 2 days. But once you start eating again, you feel like a newborn.
Google on Evernote Ex-CEO Phil Libin's experience. Again, please be careful. Read on the process of quitting hunger first.
Be healthy!
I'm excited because I believe it can bring us to a more peaceful world.
