Written By Ivan on Tech

Aug 18, 2020

The past week has seen Yearn Finance, more commonly known as yEarn Finance or yearn.finance, become increasingly well-known following a massive price rally. Specifically, Yearn Finance’s YFI token has surged over 300% in the past week. As such, many are beginning to ask the question “what is yearn.finance”. The platform recently rose to fame after the launch of its tokenized insurance product yInsure Finance, however the following article takes a look at the fundamentals that led to the creation of the entire yEarn Finance platform.

Andre Cronje single-handedly developed yearn.finance (yEarn), a yield aggregating platform on Ethereum. yEarn has grown into an ecosystem of protocols that aims to maximize annual percentage yields (APY) for its users. It plays a part in the yield farming mania that kicked off with Compound’s COMP token distribution. yEarn utilizes DeFi protocols such as Curve, Compound, Aave, and dYdX to optimize token lending.

Aug 17, 2020

As anyone following the crypto field will know, there has been a lot of media attention around Bitcoin recently, with recent gains over the past few months, a lot of people are asking is it too late to get into Bitcoin or not?

Few knew about Bitcoin during its first couple of bull runs when the price of Bitcoin went from $0.0008 to around $800, some of whom are now either driving Lambos or holding - “hodling” - tight (or a bit of both). With a current price more than 10X that of the 2012 bull run, many believe that now hearing about Bitcoin for the first time, they've missed the boat.

The “proof of work vs proof of stake” debate has been raging for a long time. Many modern projects have opted from proof of stake (POS) over the more traditional proof of work (POW).

But first, let’s look into what we mean by consensus algorithms.

Consensus is a method with which a group can reach an agreement dynamically without causing any discord in the group. As such, it's a lot more positive than simple voting, which doesn’t care about the minority's feelings. A mechanism that allows you to reach consensus is known as a “consensus algorithm.” There six rules that consensus algorithms must follow:

DeFi Deep Dive - What Is Yield Farming?

Written By Ivan on Tech

Aug 11, 2020

Those looking into the DeFi field will likely come across the term "yield farming". Yield Farming is the process of putting crypto tokens to productive use in a decentralized finance (DeFi) market to earn interest. Yield Farming takes place on the Ethereum blockchain, and yes, it is a way to earn passive income on Ethereum. But “hodling” ETH tokens is not the same thing as Yield Farming. 

This kind of farming is a creative process. It is also a managed process where “farmers” typically hop from one protocol to the next to maximize returns. However, farmers can also employ “set it and forget it” strategies. 

Yield Farming became popular with the release of Compound’s COMP governance token. When word got out that farmers could reap Annual Percentage Yields (APY) over 100%, things took off. At present, there is over $4.5 billion Total Value Locked (TVL) in DeFi according to DeFi Pulse

Governance tokens like COMP offer hodlers...
