Read More »Smart Ponzi Games in the Blockchain
On the FT’s Alphaville blog, Izabella Kaminska points to a paper by Italian academics arguing that the Ethereum technology tends to incubate Ponzi schemes. The uniqueness of the “smart Ponzi” is its capacity to protect the identity of the initiator but also its ability to persist even after being exposed. Since contracts are unmodifiable and thus unstoppable there is no central authority to terminate the execution of the scheme or force the initiator to refund victims. What’s more, the...

On the FT’s Alphaville blog, Izabella Kaminska questions the value of decentralization (and thus, blockchain technology) in intermediation. Decentralisation is, in almost all cases, not an efficiency. To the contrary, it’s a cost that adds complexity and creates an unnecessary burden for both users and operators unless centralised layers are added on top of it — defying the whole point. … At the end of the day, there are only two groups of people prepared to go to costly lengths to...

On Bloomberg, Yuji Nakamura and Lulu Yilun Chen report about conflicting views in the Bitcoin community on how to address capacity limits in the blockchain. Bitcoin Unlimited is essentially a software upgrade to the blockchain. Years ago, bitcoin’s early developers imposed a cap on the amount of data it could process. While that slowed down the network, it was seen as a necessary safety measure against potential attackers who could overload the system. Now, Unlimited supporters say the...

On Wired, Andy Greenberger discusses Monero, Dash, and Zcash, krypto currencies that provide more privacy than bitcoin and its derivatives. Unlike commercial services like PayPal, Bitcoin allows anyone to spend money online without providing identifying details. But if someone’s Bitcoin address is linked with their real identity, any transaction from that address is entirely visible on the public blockchain … Hiding those transactions requires taking extra steps, like routing bitcoins...

NZZ, November 29, 2016. HTML, PDF. Central banks are increasingly interested in employing blockchain technologies, and they should be. The blockchain threatens the intermediation business. Central banks encounter the blockchain in the form of new krypto currencies, and as the technology underlying new clearing and settlement systems. Krypto currencies bear the risk of “dollarization,” but in the major currency areas this risk is still small. New clearing and settlement systems benefit...
