Algorithmic stablecoins are decentralized and do not rely on any centralized system for circulation, transaction, issuance and redemption. This is in line with the decentralized concept of cryptocurrencies. Same as Bitcoin and Ethereum, algorithmic stablecoins apply the "Code Is Law" Principle. Just like the decentralized collaboration conducted by Bitcoin or Ethereum mining machines, decentralized participants or organizations coordinate to issue, circulate and trade algorithmic stablecoins based on rules, building a huge ecosystem in an open and symbiotic manner.
