New Report Reviews Blockchain Applications by US Federal Government
The research organization Data Foundation and IT firm Booz Allen Hamilton have published a report with five proposed questions to guide the United States federal government on where and how to implement blockchain initiatives.
Their research was published in the report “Bringing Blockchain Into Government: A Path Forward for Creating Effective Federal Blockchain Initiatives” on June 10.
According to the report, blockchain solutions make the most sense when applied to some sort of procedure with a predetermined level of consistency and a low level of agility, assuming that the immutable ledger provided by blockchain is valuable for the task in the first place.
US Retailer Target Unveils Open Source Blockchain for Supply Chain Tracking
United States-based retail giant Target is creating an open source blockchain project for supply chain tracking, according to an official blog post from the company’s VP of architecture on April 22.
According to the post, Target ran a pilot test using blockchain technology to certify its paper products along the supply chain in 2018. The blockchain used in the test period was reportedly made open source on GitHub recently as “ConsenSource” — at least as far back as two months ago, judging by the repository’s update history.
According to the GitHub documentation, ConsenSource is built on blockchain platform Hyperledger Sawtooth, one of the Hyperledger projects hosted by the Linux Foundation.
The post also mentions that Target will support the Hyperledger Grid, a project initiated in large part by Cargill, one of the company’s main food suppliers. Before bringing the project to the Linux foundation with Intel, Cargill reportedly took the initiative in making a “supply chain middleware” to record transactions and other data.
100 Bitcoin Users Perform What Might Be Largest ‘CoinJoin’ Transaction Ever
The community behind the privacy-centric bitcoin app Wasabi Wallet recently brought together 100 people to collectively execute a “CoinJoin” transaction on bitcoin in what might be the biggest event of its kind.
Some context: bitcoin itself is far from private, as users can, via the blockchain, see where coins are being transferred to and from. One effort to afford greater privacy to transactions is CoinJoin, a long-standing technology first proposed in 2013 by long-time bitcoin idea man and cryptographer Greg Maxwell. The idea is that transactions can be made more private by jumbling a number of different transactions together and then redistributing them.
At 100 transactions, Wasabi Wallet’s effort might be the biggest, but it’s certainly an advancement for the privacy tech as a whole.
