As time goes on, the priorities of society shift towards the benefit of all. In this day and age, that priority is often oriented towards preservation of the environment, given the delicate state of the air and water sources, and constant research is being done to find and support sustainable alternatives to most processes and products.

However, the main opposing force against these efforts is how engrained some of these are into our day to day life, from plastic containers to energy generation, and the implementation of technologies that could make these processes more efficient or eco-friendly might represent great…

We have reviewed many projects in the past that propose new ways to face the challenge of scalability in the current blockchain environments, an issue that can get exponentially worse as time goes by and makes the need for a solution even direr.

We have seen how sharding and partial ledger distribution makes for interesting solutions, but many are worried about how these proposals might hurt the secure landscape offered by blockchain technologies. …

Regulation and legality are still some of the most discussed topics when we talk about cryptocurrency tokens, because of how some legislations remain cautious about a technology that has widespread so quick and allows for fund raising from non-traditional ways.

The U.S. Securities and Exchange Commission (SEC) is always under the spotlight because of their regulations and, given that many projects wish to thrive in the American landscape, they must abide to these rules. …

Continuing with a series of articles discussing projects that aim to solve the current problems of blockchain technology, such as scalability and transaction processing time, and this time we will review Harmony, a Silicon Valley-based team of developers that decided to do an extensive research on previous projects to select the best factors of each of them, compile them and develop a new type of blockchain.

Improving on the Proof-of-Stake model, the BFT validation protocol, sharding and randomization, they propose a new model for blockchain that can withstand the potential latency spikes that are caused by the increase in transactions…

We have already seen how projects like the Ferrum Network are proposing ways to fight the big issues that are arising with the increase in popularity that cryptocurrencies are experiencing, mainly scalability problems and the lack of interoperability between the major blockchains and cryptocurrencies.

But situations like this one tend to spawn more than one solution, and the very nature of blockchain technology allows for multiple companies offering different ways to fix these issues. …

It finally happened. Facebook officially announced Libra as the cryptocurrency they have been working on for the last months in an alliance with more than 20 worldwide companies in the sectors of blockchain, telecommunications, payments and many others. The social media supergiant released a whitepaper and a couple of technical papers revealing important details about how the cryptocurrency will work, the development of a new blockchain and how it will all be regulated and scaled to a global scale, or at least how they will try to accomplish such goals.

The original idea of Bitcoin, coming all the way from Satoshi Nakamoto’s whitepaper in 2008, is of a “purely peer-to-peer version of electronic cash that allows online payments to be sent directly from one party to the other without going through an institution”. This is the vision that triggered the development of blockchain, cryptocurrencies and decentralized payment solutions.

And while some of the aspects of this vision were kept for a while, the evolution of cryptocurrency as a whole has made them drift apart from the original statement, and other factors — like the rise of a few exchanges and…

A solution comes in the form of payment channels between nodes. These channels act as direct connections for small transactions that require immediate completion and liquidity to support them, something that a regular transaction does not offer. Both users of the transaction must agree on the terms, as the funds will be stored in a conjoint wallet that will progressively assign funds as conditions are fulfilled. Once the final condition is reached, the refund gives each party the correspondent funds, and the transaction is finished.

These channels are unidirectional and still require some waiting for the original deposit into the…

After the great dip of last year’s “Crypto winter”, the market seems to be recovering in a healthy way, and the news seem to have reached new ears, since the announcements from great multinational companies venturing into the uses of blockchain and developing their own tokens are more frequent by the day.

But are these tokens really examples of true cryptocurrency? Or are they just fancy names for their own iterations of electronic money (e-money)? …

With Q1 of 2019 done, prominent data compiling companies are already releasing their reports on how the cryptocurrency market behaved in this past 3 months. In this article, we will be reviewing the data reported by InWara, a well known data analysis company that focuses on ICOs and, recently, in the rise of Security Token Offerings (STOs).

Before we begin, it’s important to remember that, even if ICOs are but a part of the whole cryptocurrency market, most of them end up injecting liquidity into the market and setting trends on what the general public is interested in, so their…
