Bitcoin is a cryptocurrency and a digital payment system invented by an unknown programmer, or a group of programmers, under the name Satoshi Nakamoto. It was released as open-source software in 2009.The system is peer-to-peer, and Bitcoin is called the first decentralised digital currency.

Besides being created as a reward for mining, bitcoins can be exchanged for other currencies, products and services in legal or black markets. As of February 2015, over 100,000 merchants and vendors accepted Bitcoin as payment. According to research produced by Cambridge University in 2017, there are 2.9 to 5.8 million unique users using a cryptocurrency wallet, most of them using Bitcoin.

As the first software to implement Bitcoin Cash, on-chain scaling is Bitcoin ABC’s raison d’être. Bitcoin ABC is committed to increasing the block size limit for Bitcoin Cash. But on-chain scaling involves more than simply changing one number in the software. There are various technical improvements and optimizations that must be carried out so that the system can handle larger blocks safely and efficiently. Bitcoin ABC stands for “Adjustable Blocksize Cap”, and as the name implies, it is easy for any node operator to adjust their block size limit. We are in favor of raising and eventually removing the block size limit. The miners who use our software, however, want an implementation that will work well for the blocks they produce and accept. This means that the best way we can help raise the block size limit that miners choose is by removing software bottlenecks.

A Basic Attention Token, or BAT, is the token that powers a new blockchain-based digital advertising platform designed to fairly reward users for their attention, while providing advertisers with a better return on their ad spend.

This experience is delivered through the Brave browser, where users can watch privacy-preserving adverts and receive BAT rewards for doing so. In addition, advertisers can deliver targeted ads to maximise engagement and cut down losses due to ad fraud and abuse.

The Basic Attention Token itself is the unit of reward in this advertising ecosystem, and it is exchanged between advertisers, publishers and users. Advertisers pay for their advertising campaigns in BAT tokens. Out of this budget, a small portion is distributed to advertisers, while 70% is distributed to users — whereas the intermediaries that typically drive up advertising costs are cut out of the equation to improve cost-efficiency.

The Basic Attention Token launched in 2017 following one of the fastest sell-out initial coin offerings (ICOs) of all time, with the platform raising a total of $35 million in under a minute. Since then, it has rolled out its attention-based advertising experience to users in most countries through its Brave Rewards programme.

KNC stands for Kyber Network Crystal and it is the governance token for the Kyber Network. KNC plays a critical role in determining the incentive system, building a wide base of stakeholders and facilitating economic flow in the Kyber protocol.

The Kyber Network is a decentralised exchange that provides on-chain liquidity that is applicable to any application, enabling value exchange to be performed seamlessly between different ERC20 tokens. 

The Kyber Network aggregates and maintains on-chain liquidity through a dynamic reserve pool whereby this pool contains all of the reserve entities in the system. Having multiple entities in the pool prevents monopolisation and keeps exchange rates competitive.

The 2100NEWS NWSBCT CETF token is a blockchain-based unit of value pegged to digital assets and

100% backed by a basket of crypto assets (components of the NWSBCT strategy) on the Iconomiplatform. For every settlement token minted, Iconomi holds digital assets. A NWSBCT token can track

at once, multiple digital tokens that constitute the 2100NEWS Digital Assets Blue Chip Tradable Index. It aims to cover the whole crypto market. The management of the index is essentially automatic andis done passively according to predefined parameters. NWSBCT CETF tokens offer back-and-forthconvertibility. Owners can use the CETF tokens by sending them to the smart contract and converttokens directly into a strategy on Iconomi or vice-versa.
