Intercambiar Basic Attention Token BAT a XELS XELS

BAT is an Ethereum token that powers Brave Software's blockchain-based digital advertising platform. Internet users who browse the web using Brave's free web browser (available at Brave.com) can choose to replace the ads they see with ads on Brave's ad network. Users then receive BAT from advertisers as compensation for their attention.

XELS is an eco-conscious blockchain platform enabling corporations and individuals alike the ability to easily and transparently offset their carbon footprint by purchasing tokenized carbon offset credits. Since the birth of carbon offset markets in the wake of the Kyoto and Paris agreements, fraud has been a serious problem. Bad actors have been known to sell fake or expired carbon credits, and credit “recycling” fraud can lead to double spending of unretired carbon credits (see here for an example of one of the biggest fraud cases to hit carbon credits, which even ensnared Deutsche Bank. Blockchain’s distributed ledger technology is the perfect use case for carbon credits, as it cannot be changed, reversed, or double spent. Digital assets can also be “burned,” along with a transaction hash that proves the associated credit has been retired forever. We’re initially launching the eponymous XELS token as a “platform token” to access a future suite of stable tokens pegged 1:1 to various industry-standard voluntary carbon offset credits – think of those as being the “USDT” of carbon credits.
