View ChartDai is an algorithmic stability coin issued by MakerDAO, an Ethereum based protocol designed to maintain a precise ratio of one to one with the dollar. It is mainly used as a means of lending and borrowing encrypted assets without intermediaries, creating an unlicensed system with transparency and minimal restrictions.
MakerDAO was first proposed by CEO and founder Rune Christensen in 2015, and the maker agreement, the infrastructure of Dai stablecoin, was launched in December 2017. MakerDAO's Dai model is different from other leading stablecoins. First, Dai has an unprecedented degree of decentralization. Although stablecoins such as Tether (USDT) provide a cryptocurrency supported by a reserve of legal currency assets managed by a central organization, no entity controls the issuance of Dai. Instead, users who want to hold Dai submit Ethereum based assets to a smart contract that uses these assets as collateral to maintain Dai's peg to the dollar.
Secondly, unlike most stablecoins, which use a single legal currency or cryptocurrency as collateral, Dai can use different cryptocurrencies as collateral: Ethereum (ETH), Basic Attention Token (BAT), USD Coin (USDC), Wrapped Bitcoin (WBTC), Compound (COMP), etc. At the beginning of its establishment, the Maker protocol only supported Ethereum as collateral. However, in November 2019, the technology was updated to include BAT and USDC, creating today's multi-collateral Dai system. The increase in the number of mortgaged currencies reduces the risk for users and improves the price stability of Dai. New collateral options will continue to increase through the vote of the MakerDAO community.
Third, Dai token holders can earn interest on their Dai. Those who hold MKR (MakerDAO's native governance token) set the Dai Savings Rate (DSR) and act as the guarantors of Dai, which means that their MKR tokens can be liquidated if the system crashes. This structure encourages the guarantors to ensure the normal operation of the Dai system and its mortgage tokens.
Dai is an ERC-20 token that can be purchased from centralized and decentralized exchanges (DEX). In addition, you can create and borrow Dai by opening a Maker collateral vault through MakerDAO's Oasis mirror dashboard and depositing Ethereum based assets as collateral. The Maker collateral vault, previously known as Collateralized Debt Positions (CDPs) in the early iterations of the Maker agreement, is a smart contract that holds the collateral until the borrowed Dai is returned.
The value of the collateral you deposit must always exceed the value of the Dai you issue. If the value of the collateral falls below the value of the Dai tokens issued, your collateral will be liquidated. Dai is one of the most comprehensive digital assets in the blockchain ecosystem. Once borrowed, it can be used for decentralized finance (DeFi) applications or blockchain based games, as well as elsewhere.
Dai is soft linked (or pegged) to the value of the US dollar. The greater price stability brought by the Dai stablecoin urges investors to regard Dai not only as a stable long-term store of value, but also as a feasible choice for daily transactions, which greatly expands the utility of blockchain technology and the whole cryptocurrency system.
