The commission's vice-president Jyrki Katainen, responsible for jobs, growth and investment:
”There’s a risk of a new type of protectionism, not between nations but between old business models and new ones,” Katainen said.
There is no definition of what constitutes the sharing economy. The commission describes it as new business models, primarily based on transactions between users of collaborative platforms that trade in the temporary use of products or services.
It would be wrong to see the sharing economy as a zero-sum game, where established jobs would be superseded by newcomers, he said.Monique Goyens, director general of the European consumer organisation BEUC, said the sharing economy had many benefits that had to be embraced: ”It is shaking up the consumer experience and paves the way for new opportunities in many markets,” Goyens said.

is not concerned with privacy in the libertarian, crypto-anarchic sense, but with the standard privacy requirements of financial markets. “In capital markets, it’s non-negotiable that the open interests of all parties are adequately concealed,” notes Breitman. Buterin notes that implementing privacy schemes is in the Ethereum roadmap, and in the meantime the developers of private Ethereum networks can go ahead and implement custom privacy-preserving solutions.https://bitcoinmagazine.com/articles/r-issues-buterin-s-ethereum-platform-review-papers-opportunities-and-challenges-for-private-and-consortium-blockchains-1465943849
Caso molto interessante.
Se si approfondisce il codice, il bug che ha portato all' "hack" e` una semplice mancanza di error checking nel codice dello smart contract.
Nell' articolo e` scritto:
"Stephan Tual, a co-founder of a startup called Slock.it, which helped create the DAO, says there’s one way to fix the problem and boost the ethereum economy’s robustness. Ethereum’s miners, who decide what transactions form the cryptocurrency’s permanent record, can collectively agree to do a “rollback”, rewinding the ethereum blockchain to some point before the hack happened."
E` giusta questa cosa? Penso sia meglio perdere dei soldi che lo spirito da cui e` nato un sistema come la blockchain.
Pero` e` anche vero che il rollback puo` essere attuato solo se si ha l'approvazione da tutta la comunita`.
Che ne pensate?
Buona serata,
