blockchain

The blockchain is meant for consensus, storing reddit comments or cat pictures is an expensive and inefficient misuse of the blockchain.

The title is somewhat inaccurate, as only the blockchain launched today, Ethereum itself is under active development.

Without a token, a blockchain is just a distributed database.

The grim trigger equillibrium would doom such a blockchain if it becomes successful (look up on wikipedia) 4.

The blockchain gives you most of that, although the storage bits are probably better served by something like Ethereum.

I agree, I think the website is failing because it doesn't touch on a key topic, one that you mention: How does Ethereum handle non-blockchain items?

More or less all the UK banks are at various stages of involvement with blockchain technology.

Hashes in the blockchain, when necessary, and then markets which will sell you a file when presented with the hash.

External systems can inspect the most recent values in the blockchain and act accordingly.

Just because a blockchain entry states 'x' doesn't give it any legal weight, and certainly doesn't transfer real world possessions or ownership.

Not without further integrations, but there are proposals for blockchain-based decentral name resolution etc.

While working on an installer for OpenStack I came up with the idea of implementing federation with the blockchain.

Scripts don't perform their effects in the "real world"; instead, they append values to a blockchain.
