Once hailed as unhackable, blockchains are now getting hacked

We’ve long known that just as blockchains have unique security features, they have unique vulnerabilities. Marketing slogans and headlines that called the technology “unhackable” were dead wrong.

More and more security holes are appearing in cryptocurrency and smart contract platforms, and some are fundamental to the way they were built.

Together we can thwart the big-tech data grab. Here’s how.

Our lives, online and off, depend upon decentralising power on the internet, says the Guardian columnist John Harris.

As the year unfolds, pay attention to the people who are talking about a new, decentralised internet – AKA Web 3.0 – and the possibility of data being returned to the control of the people who generate it.

In Boston, the worldwide web’s founder, Tim Berners-Lee, is working on a new way of using the internet, called Solid. Then there are the possibilities bound up with the blockchain, the system of verification that sits under so-called cryptocurrencies. Startup called Fetch is developing what it calls decentralised artificial intelligence.

MEPs call for business GDPR ‘guarantee’ on using blockchain

Businesses should not begin using blockchain technology to process personal data until they can “guarantee compliance” with EU data protection laws, a committee of MEPs has said.

The Committee on Civil Liberties, Justice and Home Affairs (LIBE) said that businesses using blockchain must, in particular, be able to respect the rights of data subjects under the General Data Protection Regulation (GDPR) to the rectification and erasure of their data.

Private Blockchains Could Be Compatible with EU Privacy Rules

A joint study between Queen Mary University of London and the University of Cambridge concluded that, whilst challenging, it is theoretically possible for organizations to design blockchain applications that fully comply with recently implemented EU ‘General Data Protection Regulation’.

Due to innate aspects of blockchain technology, like the immutability and inability to retrospectively remove customer data recorded as such, the problems become obvious when it comes to creating a solution compatible with this European regulation.

CNIL issues guidaince on Blockchain and the GDPR

When a blockchain contains personal data, the GDPR is applicable. The architecture and characteristics specific to blockchains will, however, have consequences on how personal data is stored and processed. To address this matters, French data protection authority CNIL recently published guidelines “Blockchain and the GDPR: Solutions for a responsible use of the blockchain in the context of personal data“.

How PrivacyChain could solve one of consent management’s biggest problems

The new privacy blockchain proposal — announced last week by the Interactive Advertising Bureau’s Tech Lab in conjunction with identity resolution provider LiveRamp — could solve one of the biggest problems of consent management.

When a user allows a publisher to use her info for marketing or ads, the consent info is passed via a TCF-suitable consent management platform to vendors who have been approved by the publisher, such as ad exchanges, data management platforms, tag management platforms and so on. But those vendors could share the info with other vendors, or there might be vendors on the web site who got hold of the info without the publisher’s knowledge.
