What is a blockchain

A blockchain is a public, digital ledger in which transactions are recorded in a linear, chronological order. Its content is de facto secured by an inherent consensus mechanism based on mathematical functions. Some consider the blockchain technology and all its existing and future applications as part of the 4th industrial revolution, profoundly transforming our society.

What is a secure chip

A secure chip is a tamper resistant platform capable of securely hosting applications and data in accordance with the rules and security requirements set by pre-authorized applications and people. Hacking a secure chip takes formidable efforts, while information can be easily extracted from generic microcontrollers by amateurs.

What is a cryptocurrency

A cryptocurrency (crypto) is a blockchain based currency application. The biggest crypto, Bitcoin, was created as an alternative, secure currency system in the midst of the financial crisis back in 2008. Most define Bitcoin as a new asset class, similar to gold, referring to it as the ‘digital gold’.
