But where exactly is the image data stored?

If you read the source code ( https://etherscan.io/address/0xb5fe93ccfec708145d6278b0c71ce... ), you'll see that it only stores links to images in the Ethereum blockchain. Thus it is the buyers responsibility to make sure that the image stays. The best way to do that would probably be to store it on IPFS or something else. [Edit] The (probable) reason why they're not storing the images on Ethereum is that that would…

Just how expensive would it be? I mean, for every pixel they are getting 0.001 ethers so surely a part of that could have been used for storing inside the blockchain? That would make it completely permanent.

> I can't think of any internet stars I'm particularly desperate to see go into politics, and that's not because I'm delighted by the status quo This is a good point, but consider how a lot of politics is kept off of typical social media channels, either due to overarching censorship or decency concerns, because of concerns about repelling advertisers, or simply because the main issues we are fed have mostly to do wi…

I think you must inhabit different social media worlds from me. I see an enormous amount of politics on social media, which tends to be even more lowbrow and fear-driven than the mainstream media for reasons which have nothing to do with capital and everything to do with clicks.

Well, I'd argue that what you're seeing is a second-tier of power/wealth-hungry individuals. The first tier occupies our political leadership.

The behavior is basically identical, but with dramatically different payouts. Both involve finding a tribe and riding that tribe's enthusiasm to greater notoriety and wealth.

By the way, here's a GIF of what the buying process looks like: https://gfycat.com/BleakSimilarGermanspaniel This is the part that blows my mind, it feels like magic every time. (P.S. Thanks for your support, Chris!)

That GIF is neat, but I don't see your ad when I look at the page.

It looks like they did it on the Rinkeby Testnet for that demo so they wouldn't have to spend real Ether.

Very cool, thanks for sharing! Another challenging dimension is to balance what the EVM is good for with the problem you're actually trying to solve. It's certainly interesting to work in an environment where inefficiency literally translates into money. Going for literally every pixel is too expensive, so we went for deci-pixels (10x10 pixel blocks). Incidentally, the original Million Dollar Homepage took the same a…

How expensive is the search for empty blocks going to be towards the end? Would it be possible to introduce a more efficient algorithm in the future, or would it invalidate past sales?

We have an array index lookup for empty slots, the search should be constant time throughout.

A follow-up question: can you insert javascript:{ stuff } as the URL your ad links to? I'm actually curious if you could make "dangerous ads" where a stray click from a logged in account would trigger a transaction.

Good point, I added a check specifically for this.

Also, what if somebody links to an enormous, hundred-megabyte sized image?

You pay for gas when you send a transaction (i.e. buy an ad or publish an ad). For displaying, if you browse with Mist or MetaMask, you're pulling the data from the blockchain. When you don't, we show you the ads statically by using a Ethereum gateway. Either way, reading doesn't cost gas, just bandwidth to keep the blockchain in sync.

Thanks. How is the Ethereum blockchain suppose to support hosting this data forever if nodes don’t get paid for it?

The data literally is the blockchain.

Ethereum provided two types of data storage. One you pay for bytes used but your script has access to this like normal memory.

The other type is outputting log events. DAapps can't read these but blockchsin explorers can read them directly from the underlying blockchain data.

Author here. My friend and I have been doing some smart contract audits, and we wanted to build a fun contract ourselves. We remembered the Million Dollar Homepage from 12 years ago, and decided to reimagine what it would look like today _on the blockchain_. Not an ICO, more of an experiment / art project. We present, the Thousand Ether Homepage: https://thousandetherhomepage.com/ The smart contract itself: https://e…

I would love to start an art project that can buy me an Aston Martin :)

I did a few community cryptocoin projects, they haven't afforded me anything (yet) but served as learning experiences, I consider them art projects, there is:

YC Coin: distributed karma for HN on the Ethereum blockchain (ycco.in)

Also Facebook Coin, instagram Coin and reddit Coin (just add co.in).

Perhaps the best "art" project is www.dotcomco.in itself. If you liked the dotcom bubble you will love the cryptocoin bubble, so I mesh the two. One domain owner has contacted me willing to list their domain for sale and was willing to pay the listing price of 1BTC.

I am also an attorney and begun offering community smart contract/blockchain services (loyalty programs and asset-backed tokenization) to my clients and I use the above as my portfolio of work. So far I have had a local craft brewery interested in me developing a blockchain loyalty program and some private aircraft owners interested in creating tokens representing economic interests in their planes.
