denisnazarov··on Why blockchains won't revolutionize publishing
Check out some of the experiments the users of Mirror are running. They have used Mirror to crowdfund their writing, raising almost 75 ETH so far, and are also selling NFTs to sustain their writing practices.

denisnazarov··on A Beginner's Guide to NFTs
Best explanation of NFTs and virtual goods I heard was from pmarca and bhorowitz on Clubhouse yesterday:

- The Honus Wagner baseball card is $0.50 of physical goods (cardboard/ink) and $3M of virtual goods

- A Basquiat painting is $100 of physical goods (paint and canvas) and $1M of virtual goods

- A rare Nike sneaker is $5 of physical goods (plastic/rubber) and $500 of virtual goods

NFTs are going to take this phenomenon to Internet scale.

We made the conceptual leap from physical gold to digital gold with Bitcoin. We will do the same for all other objects with cultural value with NFTs.

denisnazarov··on Colony: A platform for open organizations
For 1: The colony fixes the bug and creates a fork of the contract state (balances, etc) before the hack, so everyone has the same balance but there is no longer a bug. There should be consensus on using this fork going forward because everyone that has created value or invested is incentivized to do so.
denisnazarov··on Tendermint 0.10.2
> serves as a building block for Proof of Stake networks.

Can you elaborate on this, as there is almost no mention of PoS in the post?

From a high level, your response to my previous comment can be interpreted as the validators being "hardcoded" upfront, which would be very different decentralization properties from PoW systems.

What assumptions does Tendermint make in contrast to PoW systems, and what applications do you see it being most useful for?

denisnazarov··on Tendermint 0.10.2
How does Tendermint consensus compare to Nakamoto consensus? Are 2/3 of the nodes expected to be honest? How is validator membership established/enforced?

Should not affect the majority of the collection. For now you should be able to click to the source and find the original image there. Sorry for the inconvenience!
denisnazarov··on Show HN: Mediachain Attribution Engine
Hey HN!

I'm Denis, one of the people working on Mediachain! We're really excited to launch Mediachain Attribution Engine today!

We think it's the best image search engine for creators. You can find free, high quality images that you can share and re-use, with attribution automatically baked in.

Mediachain Attribution Engine makes it easy to find a great image that you can feel good about sharing or using in your blog post, presentation, website, etc.

You can upload any image from the web to find out who made it and where it came from. If Attribution Engine doesn’t know the creator, it’ll suggest visually similar images that are licensed for re-use and give credit to the author.

Attribution Engine is the first application powered by decentralized, open data in Mediachain and is built on top of the newly launched protocol architecture (v1.0).

Creators can sign up to register works and developers can use the data in their own apps, or contribute directly to Attribution Engine by following our quick start guide.

denisnazarov··on Mediachain enivisions a blockchain-based tool for identifying artists’ work
The goal of Mediachain isn't to enforce scarcity of media online, but to help creators benefit from the scale of sharing. Today, an image can easily go viral without viewers knowing who the author was. Mediachain makes sure that the creator can be present wherever the content goes, automatically.

Our view is that bits are easily reproduced and there is no way to stop that, and until now there's been no easy way for creators to benefit from that. Mediachain allows creators to connect directly to their audiences through the content itself. This way, gratitude can be exchanged through attribution, and in the future, even a payment directly through the content.

denisnazarov··on Mediachain: A Distributed Metadata Protocol built on IPFS
Thanks dang, should we try resubmitting the RFC then?
denisnazarov··on Mediachain enivisions a blockchain-based tool for identifying artists’ work
We're creating a completely open, decentralized media library and our goal is to help creators reach their audience directly through their content.

We believe that value should follow the content, instead of flowing from a platform.

Today, Mediachain helps preserve attribution for creative works wherever they go, so you can know the creator of that anonymous viral image you see in your feed.

In the future the same infrastructure will enable financial exchange directly between a creator and their audience through their works.

We've written some more about the implications of Mediachain here: https://blog.mediachain.io/the-gif-that-fell-to-earth-eae706... https://blog.mediachain.io/what-a-blockchain-for-music-reall...

denisnazarov··on Mediachain enivisions a blockchain-based tool for identifying artists’ work
The perceptual recognition technology is similar to Shazam or Google Image search (or Tineye), identifying media based on how it looks or sounds.

This allows Mediachain to always point back to information about an image, even if its metadata is stripped out as it goes viral, for example. Near duplicate image detection is quite far along and works well for images that are cropped, distorted, etc.

More on our approach in this post: https://blog.mediachain.io/perceptual-resolution-9c00ad5ca55...

Details on the implementation in this RFC: https://github.com/mediachain/mediachain/blob/master/rfc/med...

denisnazarov··on Mediachain enivisions a blockchain-based tool for identifying artists’ work
Our goal is to make the monetization of media follow the content, instead of flowing from the platform like it does today.

Today, Mediachain can automatically link an image to who made it. That same channel can be used to transfer value directly through content in the future. We believe that this will create a huge opportunity for developers to build new media applications that reward creators directly through their content, no matter where it is.

denisnazarov··on Mediachain enivisions a blockchain-based tool for identifying artists’ work
Any metadata that is stored in EXIF or part of the file can be easily stripped out. This is why Mediachain uses perceptual recognition technology similar to Shazam or Google Image search to identify media based on how it looks or sounds, automatically resolving to metadata stored in Mediachain. Near duplicate image detection is quite far along and works very well even for images that are cropped, distorted, etc.

More on our approach in this post: https://blog.mediachain.io/perceptual-resolution-9c00ad5ca55...

denisnazarov··on Mediachain enivisions a blockchain-based tool for identifying artists’ work
The short answer is reputation. Consumers of the data should be able to filter by cryptographic signature to prioritize users that have more reputation over ones that don't. A timestamp is just one piece of metadata.

For example, on a platform like Soundcloud there are many Rhiannas but it is obvious which account the "real" Rihanna is because she has the most followers, likes, etc. Popularity can be another data point.

Projects like Blockstack already offer solutions that take a similar approach, allowing you to link your social media accounts so your identity is more trustable.

We also envision developers and trusted organizations like Creative Commons or DPLA creating indexes on top of Mediachain to help users filter the data.

Distributed Systems Engineer

A seasoned systems engineer with experience or interest in distributed, decentralized, and peer-to-peer systems. An empathetic human being who understands open data can’t thrive in an environment that isn’t healthy and inclusive.

You should be comfortable confronting a massive problem and deciding, “I’ll start here.” It’s the hardest part of a project like this and we’re still only scratching the surface. We’d love to hear about any relevant experience you have designing and iterating on large projects.
