I built something like this 2 years ago. And it's 3D! http://etheria.world

Would be interested in hearing if/when you received attention to it and how ETH prices affected users willingness to spend 1+ETH to play/us. Any future plans to keep it going and add to it?

There's no way a single shared blockchain would be able to serve the whole world. The number of transactions per second is one thing. The size of the chain is another. If we all start throwing money transactions AND idle drawings into the same bucket, it will overflow. Something needs to change. The current architecture clearly does not scale. Maybe something more like Pascal Coin would be better able to scale up to…

I do not invest in ETH. The reason why varies, but essentially I hold a belief that various portions of their stack have various levels of trust which are not well understood. For example, the Ethereum community has "allowed" people to use poorly constructed libraries to build contracts that were later invalidated by someone "goofing around". Other incidents show the stakeholders are willing to change core code to get their stored values back (or their associates stored values back). These issues are not to say the core chain of Ethereum is of low trust. It is not.

You are correct in assuming there is no way for a scalable and fast blockchain to store data that serves the worlds needs. Ethereum is built on the promise to do away with current decentralized services, by way of allowing the identity and value used to be placed on their chain and executed using some programmable logic, in a way that is trustworthy.

Of course we've been doing this for years with centralized services. Images drawn by people, for example, have no business being in a chain, but they could be "pinned" to the chain by way of some loose, lower trusted consensus than the main chain. A few of us could store it for a price using IPFS/Filecoin while others of us make a statement that we know the file in question exists by signing an entry on a main chain - instead of just putting the image there in total.

I think a few dozen tiles were purchased at 1 ETH when it was about a dollar per ETH. People seemed to like it although it was challenging to build things. I can see in the contract data that some people bought tiles, mined blocks, but didn't understand how to place the blocks on the tiles, so the blocks remain hidden.

Anyway yeah I'm thinking of resurrecting it soon. I've kept an entrepreneurial/techie ear open since I built it and I think I finally know what I want to do to bring it back to life.

As far as ownership, I'll probably just buy all the remaining tiles myself (the money goes to me anyway) and then sell at more reasonable prices on the secondary market.

I agree completely. A shared ledger is a great idea, but not when anyone can write almost anything into it. Then it starts turning into some sort of massive torrent that has to be synced around the world.

If you've tried recently to sync up a self-hosted ETH wallet app, you've probably noticed what an incredibly long time it takes to get the whole blockchain. Meanwhile the HDD is thrashing around like crazy; if you're not using an SSD then forget it. Wallet apps like Parity are a little more forgiving (probably smarter in how they handle the blockchain), but still, it's dozens of gigabytes already.

To me, the single, shared, universal blockchain idea seems more like a proof of concept. It's also pretty hard to ask every node in the network to see every possible transaction. I am virtually certain that whatever ends up taking over the world will not operate that way. Things just don't scale like that.

Ah back when Ethers were $7 each instead of the $800 today

The real question is whether your poor investment decisions are relevant to the discussion of this thread

These are commodities, broken things about them makes the more valuable or scarce, just like when an oil pipeline is destroyed in a conflict zone. Your opinion about oil has no bearing on you making money.

Have a look into blockchain sharding. There is also Lightning and Plasma, though they are far less promising.

What is your rationalization for saying Lightning is not promising? I think that, given the state of the ecosystem, spreading opinion around as fact is not healthy.

It sounds like Lightning is attempting to solve an unsolvable NP-hard math problem regarding routing. [1]

The Lightening network is mostly a gimmick attempt to save the design failures of scaling from the BTC communities refusal to increase network bandwidth in order to save disk space.

That and for the Lightening network to work without opening up a dozen "deposit channels" into everywhere you shop, users will be pushed into larger liquidity hubs, i.e. payment processor middlemen which is ironic given this is exactly what Satoshi's white paper sought to avoid.

Y'all need to calm down a little.

It was supposed to be provocative

someone took a hard look at the project and made up irrelevant reasons not to participate in owning the underlying gas of the network, forfeiting a 11,800% profit from $7 after the DAO incident to $830 today, and maintains that opinion while continuing to masquerade them as related!
