Over the years, the concept of a virtual, decentralized currency has gained acceptance among regulators and government bodies. Although it isn’t a formally recognized medium of payment or store of value, cryptocurrency has managed to carve out a niche for itself and continues to coexist with the financial system despite being regularly scrutinized and debated.
If you have wondered why sites that give away free cryptocurrencies exist at all, here is the answer; Sites and apps that offer you a way to get free Ethereum make their money from advertising, and sometimes by using your CPU to help with their mining activities. They are also introducing you to cryptocurrency, in the hope that you will buy related services from them later.
Bitcoin was launched in January of 2009. It introduced a novel idea set out in a white paper by the mysterious Satoshi Nakamoto—bitcoin offers the promise of an online currency that is secured without any central authority, unlike government-issued currencies. There are no physical bitcoins, only balances associated with a cryptographically secured public ledger. Although bitcoin was not the first attempts at an online currency of this type, it was the most successful in its early efforts, and it has come to be known as a predecessor in some way to virtually all cryptocurrencies which have been developed over the past decade.
Ethereum is what is known as an open-source, blockchain-based, distributed computing platform. It has smart contract features that enable the processing of contractual agreements online. These smart contracts can be used to process the transfer of assets, such as shares, property, and money. When a smart contract is run on a blockchain, it becomes a self-operating program. It will automatically execute once certain predefined conditions have been met.
That’s not to say there aren’t risks in DeFi. Many are worried that the frenzy around speculative activities such as “yield farming” and interconnected leverage could set off a systemic crisis. If that happens, maybe Bitcoin can offer an alternative, more stable architecture for it. Either way, ideas to improve DeFi are coming all the time – whether for better system-wide data or for a more trustworthy legal framework. Out of this hurly burly, something transformative will emerge. Whether it’s dominated by Ethereum or spread across different blockchains, the end result will show more cross-protocol synergy than the chains’ warring communities would suggest.
