i posted below about big pharma using blockchain to share private data as an example, as another: most of the gamers / digital art enthusiasts are newcomers to the "blockchain field" and only in it bc of the value they derive from the scarcity / durability and therefore tradability of these items

i would argue what blockchain has given us today with permissionless open finance, decentralized organizations / voting, NFTs / digital art, etc. is plenty of early indications of value. also the fact that the token business model exists is precisely the reason there's less of a traditional "ARR" mindset in the tools and apps.
the criticism isn't entirely invalid: the blockchain space has a lot of proving to do – there's a lot more work ahead than behind

That said there are many examples of blockchain being useful in smaller settings, e.g.:
> "Last June, 10 of the world’s largest pharmaceutical companies – including Johnson & Johnson, AstraZeneca and GlaxoSmithKline – announced they would pool data for an AI-based search for new antibiotics, which are urgently needed as antibiotic-resistant bacteria have proliferated across the world, threatening the growth of untreatable disease. > That historic agreement was made possible by the development of a secure, blockchain-based system that allows an algorithm to search rival companies’ data with full traceability – but without revealing commercial secrets to competitors. The advantage of using blockchain is that companies can trust the code rather than their partners." [1]

Asking "what is blockchain good for other than cryptocurrencies" is like asking "what is internet good for other than websites" pre-broadband
Blockchain TODAY is the backbone for a $200B financial system that lets you store or transfer billions of dollars worth of value within minutes for cents in transaction fees, completely peer-to-peer with no middle men
Scalable blockchains will generalize this same benefit to let developers add crypto into any kind of application (just like we had web-apps, we'll have crypto-apps):
– Instant global p2p payments
– Completely transparent, efficient marketplaces / clearinghouses with no switching costs
– Ability for users to own their own data and assets, removing liability for platform operators but also eliminating lock-in
– Open source, open state, serverless code that runs directly on-chain and thus can be built on with no platform risk (google "blockchain composability")
– Software that can be governed / controlled by the users that have stake in it

Hey Hackernews! We are excited to show you Flow Playground, the first time anyone can write smart contracts in Cadence, our new programming language
Cadence pairs linear types with object capabilities to create a secure and declarative model for digital ownership
All of this was built with love over the past couple of years by a small yet mighty team based in Vancouver, Canada
For more on resources, check out our blog post (https://hackernoon.com/resources-programming-ownership-on-th...)
Smart contracts are uniquely suited to managing ownership of valuable assets, but most programming languages – even those designed specifically for smart contracts – don’t have any native abstractions for managing ownership, until Resources.
Resources have 3 rules:
1. Each Resource exists in exactly one place: no duplication, double-spend, or accidental deletion
2. Ownership of a Resource is defined by where it's stored: no central ledger or smart contract
3. Access to methods on a Resource is limited to the owner
Check it out and let us know what you think
