Future of Blockchain-based Data Marketplaces: Challenges and Impact

Future of Blockchain-based Data Marketplaces: Challenges and Impact
Join us as we have Michelle Yeo of DATAVLT and Daphne Ng of JEDTRADE share their insights and experiences in the blockchain-based data marketplaces! What’s Next for Data Marketplaces? AI has created a huge demand for user data and Blockchain could give individuals the ability to control and sell their own. To develop AI applications, companies need access to massive datasets to create predictive models. This is why tech giants with significant amounts of data like Facebook, Amazon, Microsoft and China’s Baidu, Alibaba, and Tencent are leaders in the field of AI. For others, obtaining a lot of quality data can be challenging. As a result, emerging blockchain startups have begun offering “data marketplaces” that widen access to AI training data. Why then are data marketplaces still not gaining sufficient traction? Blockchain: Solving the Data Privacy and Security Conundrum With recent breaches in data protection from several large organisations, there is increasing concern in data privacy and security from individuals as well as regulators. This ultimately poses a challenge to open data marketplaces. Blockchain can be a solution to this data privacy and security conundrum by providing trust and immutability to the data sharing process. However, managing and regulating consent on the blockchain alone may not be sufficient. How can we leverage technology to protect the data of users and yet allow meaningful analysis at the same time?

One Week Into SegWit, Hardware Wallets Lead the Pack in Slow-But-Sure Roll Out

After a years-long development process and even more debate and political struggle, Segregated Witness finally activated on the bitcoin network last week. The protocol upgrade introduced a number of benefits which can enable more advanced second-layer protocols. It also offers a block size limit increase for wallets that utilize the new feature, meaning users can enjoy lower fees and faster confirmation times.

One week in, Segregated Witness has been implemented in several wallets, though overall adoption is off to a bit of a slow start. While many wallets and services indicated prior to the activation that they would be ready for the upgrade, many are taking a bit of a conservative approach when it comes to main-net release, while others have since faced unrelated difficulties that demanded their attention.

So far, hardware wallets are among the first to have jumped on the new opportunity. Both Trezor and Ledger have fully implemented and enabled Segregated Witness. This is not very surprising: Hardware wallets stand to benefit from SegWit more than most wallets, as it helps to significantly speedup the signing process.

“But we mostly implemented Segregated Witness to help the network first,” Ledger CTO Nicolas Bacca told bitcoin Magazine. “The more Segregated Witness transactions are used, the more space there is for everybody. In a way we’re also doing our part to disarm the 2x part of the SegWit2x hard fork.”

Another hardware wallet provider, Digital Bitbox, also implemented Segregated Witness in its firmware, cofounder and bitcoin Core contributor Jonas Schnelli told bitcoin Magazine, but it still requires a compatible desktop app to utilize the feature. This is a work in progress.

Full node wallets like bitcoin Core are also in the process of implementing Segregated Witness. But bitcoin Core developers decided to not include the feature straight away in order to avoid edge-case attacks that become harder to execute as time passes. bitcoin Core will instead release a new version of the software, 0.15.1; this could take another month or two before it’s available.

As for regular wallets, it seems that Blockstream’s GreenAddress could well be the first to offer the feature.

“It’s days away,” GreenAddress developer Lawrence Nahum told bitcoin Magazine. “We were ready a while back; however, during testing we found that fees were a bit higher in one of our wallets. That’s because some software libraries available now weren’t available when we implemented SegWit. At this point it’s mostly a matter of more testing.”

Most other wallets are also in various stages of implementing the feature, but for various reasons haven’t gotten to the point of release quite yet. In some cases, like BitGo and BTC.com, this had to do with the prioritization of integrating bitcoin Cash into their service; the new cryptocurrency launched unexpectedly only a couple of weeks ago. Similarly, Mycelium told bitcoin Magazine it has been implementing new features which diverted some time and attention away from SegWit.

Other popular wallets, including Bitcoin Wallet (also known as Schildbach’s bitcoin Wallet), Breadwallet, Electrum, mSIGNA, as well as webwallet Xapo confirmed that they are implementing SegWit, and all told bitcoin Magazine that they expect this should be available soon — though none gave a specific timeframe for it.
