Building for the Blockchain
Yet so far I still see almost <i>nothing</i> on the block chain (beyond its core currency use case) that is useful outside the domain of block chain stuff.<p>The only exception is things like Sia, and that&#x27;s not cost or convenience competitive with Amazon S3 or Backblaze.<p><i>Where is the value here?</i> When I visited this I was expecting to see at least something about building something useful for... something... Building <i>what</i> for the blockchain?<p>Oh kitties. Yeah.<p>I am absolutely aware of the fact that early stage tech often looks like a toy, but here&#x27;s the thing. PCs were a toy but it didn&#x27;t take long at all (VisiCalc, etc.) before they had actual uses. BBSes were a toy but they were immediately useful to their users for trading data and messaging.<p>We are now about eight years into block chain and beyond its one core use cases there is almost nothing. Whatever value has been delivered seems extremely minor compared to the vast sums of money being spent, making this perhaps the worst ROI I&#x27;ve ever seen.<p>Can someone provide a counter example? What are people doing in the real world with this stuff?
