The Basic Attention Token comprises various components, including attention measurement systems, analytics dashboards and machine learning algorithms. Integration of BAT into a given host application involves implementing BAT Ads, a system that matches and displays ads to users based on locally stored data. Ad targeting is performed wholly on-device, removing the need for third-party tracking. BAT is focused on the Brave browser. Brave is an open-source, privacy-centered browser designed to block trackers and malware. It utilizes blockchain technology to anonymously and securely track user attention, which translates into rewards for publishers.

The makers of BAT indicate that the user's private data and tracking information is stored only on the user's device, ensuring that it is anonymous and private. Created back in 2016, the Basic Attention Token has one of the biggest names behind it, that of Brendan Eich, the creator of JavaScript and the legendary co-founder of Mozilla. Other noteworthy team members include Brian Bondy, lead developer and co-founder of Brave and Scott Locklin, senior engineer, and co-founder of Kerf Software.' Basic Attention Token is created by the team that built the Brave browser, an open-source, privacy-focused browser that blocks ads and trackers.

'Tael is a digital token for safe consumer products. Thanks to its ability to be seamlessly integrated by third parties, it allows for a wide token use-case through interchangeability of the loyalty tokens on the blockchain. Tael’s first use-case is seen in Techrock’s safe consumer products ecosystem. Techrock applies banking-level, tamper-proof NFC smart-labels to consumer goods, pairing them with their digital representations on the blockchain. Consumers ‘touch’ the label with their smartphones to verify a product’s authenticity, discover the product’s journey along the supply chain, and be rewarded for their purchase. Techrock protects products where authenticity matters, such as infant formula, cosmetics, alcohol, and supplements. Tael tokens are used in the loyalty point ecosystem to reward consumers and encourage behavior in the Techrock channel while generating unique data for all companies in the value chain. Tael’s vision is to bring blockchain based payments into the mainstream, across Asia and beyond.'
