The history of smart contracts is longer than most of us are inclined to assume. How it all started, who was behind the concept, and what was required to make smart contracts possible in practice \u2014 all of that you can learn in the first part of this exposition. Here we are going to explore practical implementations of the technology and then top off with what smart contracts are trying to achieve, what their mission is.As smart contracts were first introduced in the cryptocurrency space, it is little wonder they got universal adoption for use with crypto. Bitcoin and other cryptocurrencies are mostly utilized as vehicles for trading and often serve as investment assets, so the first use cases of smart contracts were associated with this field. More specifically, smart contracts lie at the core of the vast majority of decentralized exchanges like IDEX and decentralized stablecoins such as MakerDAO\u2019s Dai that work as proxies to fiat currencies on these exchanges.Smart contracts are the sum and substance of the newest approach to decentralized trading based on liquidity pools and automated market maker protocols. Conventional exchanges, whether decentralized or otherwise, use order books to discover the market price through the equilibrium of offsetting orders. Here you trade against other traders. With liquidity pools, however, you trade directly against a smart contract where the price is determined by the balance of pooled reserves aka liquidity held by the contract.The exchanges leveraging this technology such as Uniswap, Curve, Balancer, Kyber, 0x, dYdX have easily overtaken all other decentralized exchanges thanks to the simplicity of use and trustless nature that smart contracts and decentralized applications built on top of them provide. And you can not only trade there but also provide liquidity through the same smart contract and earn by accumulating fees. With centralized\u2026<\/p>","protected":false},"excerpt":{"rendered":"
