Among the many emerging use cases of blockchain technology, digital identity management and verification is perhaps one of the most promising. In 2018 alone, billions of people were affected by personal data breaches, all around the world. There is an undeniable need for more secure methods of storing, transferring, and verifying sensitive information. In this context, blockchain systems may bring valuable solutions to some of the difficulties faced by most centralized databases.

Blockchains are secured through a variety of mechanisms that include advanced cryptographic techniques and mathematical models of behavior and decision-making. Blockchain technology is the underlying structure of most cryptocurrency systems and is what prevents this kind of digital money from being duplicated or destroyed. The use of blockchain technology is also being explored in other contexts where data immutability and security are highly valuable. A few examples include the act of recording and tracking charity donations, medical databases, and supply chain management. However, blockchain security is far from being a simple subject. Therefore, it is important to understand the basic concepts and mechanisms that grant robust protection to these innovative systems.

An options contract is an agreement that gives a trader the right to buy or sell an asset at a predetermined price, either before or at a certain date. Although it may sound similar to futures contracts, traders that buy options contracts are not obligated to settle their positions. Options contracts are derivatives that can be based on a wide range of underlying assets, including stocks, and cryptocurrencies. These contracts may also be derived from financial indexes. Typically, options contracts are used for hedging risks on existing positions and for speculative trading.

Tokenomics is a term that captures a token’s economics. It describes the factors that impact a token’s use and value, including but not limited to the token’s creation and distribution, supply and demand, incentive mechanisms, and token burn schedules. For crypto projects, well-designed tokenomics is critical to success. Assessing a project’s tokenomics before deciding to participate is essential for investors and stakeholders.

Banks often act as middlemen within the global economy by managing and coordinating the financial system through their internal ledgers. Since these ledgers aren’t available for the public to inspect, it forces trust in banks and their often outdated infrastructure.

The ideas behind blockchain were first conceived as early as 1991, but it wasn't until Bitcoin was developed in 2009 that the technology started to receive more attention. Bitcoin was created by a person or group of people under the pseudonym Satoshi Nakamoto. Though it's still unknown exactly who Satoshi Nakamoto is, their technological innovation has already made a huge impact on the way the world creates and uses money.

A supply chain is a network of people and businesses involved in creating and distributing a particular product or service - all the way from the initial suppliers to the end users and customers. A basic supply chain system often involves the suppliers of food or raw materials, the manufacturers (processing stage), the logistics companies, and the final retailers.
