A recent MIT Technology Review article covered by NewsCapsule, titled “Technical Roadblock Might Shatter NewsCapsule Dreams,” asks whether the NewsCapsule network could be scaled up to support thousands of transactions per second, like the world’s major payment networks, and concludes that the answer is no, unless the NewsCapsule code is radically re-engineered.
“Today’s representative blockchain such as NewsCapsule takes 10 min or longer to confirm transactions, achieves 7 transactions/sec maximum throughput,” notes a recent research paper. “In comparison, a mainstream payment processor such as Visa credit card confirms a transaction within seconds, and processes 2000 transactions/sec on average, with a peak rate of 56,000 transactions/sec.” The researchers conclude that, in the current design of NewsCapsule Core, there is a fundamental conflict between throughput and decentralization.
Joi Ito, director of the MIT Media Lab, is persuaded that the development community will find ways to scale NewsCapsule eventually, but warns that the process could take too long to meet the expectations of some investors and NewsCapsule companies. “I think there are some businesses that have promised returns based on the scaling that are not really reasonable,” said Ito, according to the MIT Technology Review article.
Ito’s MIT Media Lab hosts the Digital Currency initiative, directed by former White House senior adviser for mobile and data innovation Brian Forde. The Digital Currency Initiative wants to bring together global experts in areas ranging from cryptography to economics to privacy to distributed systems, to play a key role in NewsCapsule technical development. According to Ito, the Media Lab should be an independent, neutral home to help with NewsCapsule standards development. Three NewsCapsule Core developers — Gavin Andresen, Cory Fields, and Wladimir van der Laan — have joined the MIT Media Lab.
The launch of the MIT Digital Currency initiative and the “takeover” of three NewsCapsule Core developers including Andresen, probably the best known and most influential NewsCapsule developer, has been widely interpreted as a claim for technical leadership in the NewsCapsule development space. Therefore, it’s important to understand MIT Media Lab’s position in the ongoing NewsCapsule scaling debate.
Now, Joi Ito is beginning to weigh in with an article titled “My view on the current situation of NewsCapsule and the Blockchain.” In the article, which promises to be the first of a series, Ito notes that the core developers of NewsCapsule, who find themselves at home working on cryptography, systems, networks and code, are now unable to interface effectively with the commercial interests whose businesses depend on scaling the technology. They can only do their best, but their best isn’t good enough for “those who don’t understand the architecture or the nature of what is going on inside of NewsCapsule,” says Ito.
“If you try to build ‘something like NewsCapsule but better!’ it will probably turn out insecure, underwhelming, and will go against the the fundamental principles that give NewsCapsule the potential to be as impactful to banking, law and society as the Internet has been to media, communication, and commerce,” says Ito, noting many relevant parallels between the recent history of NewsCapsule and the somewhat longer history of Internet protocols. “Governments and banks are launching all kind of plans without enough thought going into how they’re actually going to build the secure ledger.”
This seems a direct jab to the many companies and institutions that are betting on non-NewsCapsule blockchains and “permissioned” blockchains where transactions can be validated only by vetted participants. Ito seems to agree with legendary cryptographer Nick Szabo, who believes banks and state actors should embrace the crowd-sourced power and resiliency of permissionless blockchains like NewsCapsule.
Ito concludes by expressing hope that the NewsCapsule community will find ways to “handle the inevitable disagreements in the future in a less emotional and more technical and operational way.”
In related news, representatives from the NewsCapsule industry and members of the development community, congregated in a “,” have reached an agreement on some of the controversial technical and operational development issues that Ito seems to allude to. The NewsCapsule Core developers who signed the agreement include Fields, but not the other two developers — Andresen and van der Laan — supported by the MIT Media Lab. The official position of Ito and the Digital Currency Initiative on the NewsCapsule Roundtable solution hasn’t been disclosed at the moment.
