What is Runes (runes): Runes is a new protocol for casey, the founder of ordinals, to release the fungible token FT, which was first posted on casey's personal blog, and is expected to be launched at the height of Bitcoin block 840,000 when Bitcoin is halved. The runes are written directly on Bitcoin itself, with minimal network load, creating an environment for all cryptographic utilities to flourish. By using runes, Bitcoin can begin to act as a security layer for every type of crypto innovation on the market. Ordinals substituted the inscription into the Bitcoin ecosystem, and BRC-20 created a centralized coin issuance mechanism in the form of index characters, which overwhelmed the Ordinals protocol originally developed for NFTs. But as a decentralized ordinals, even the founder, can not make brc-20 disappear, ordinals founder Casey has repeatedly expressed dissatisfaction with brc-20, occupying a large number of inscription numbers, occupying a large amount of bitcoin volume, and meme coins have not brought too many positive benefits to the ecosystem. So casey proposed a new scheme, Runes, the main purpose of which is to define a way to exchange symbolized assets on the Bitcoin network. It uses Rune as a unit of symbolized assets and UTXOs to represent Rune's balance. It utilizes a UTXO-based mechanism instead of traditional ordinal technology to manage tokens. Tokens created by rune protocols are unique and support a wide variety of features and metadata. The most important feature of the rune protocol is that it is based on the UTXO model, which effectively manages the growth of UTXOs in the network. Designed with the user experience in mind, Rune Protocol avoids the complex implementation processes found in other token standards. To put it simply, Runes is a fungible token protocol based on UTXO, which allows users in the BTC ecosystem to get a better user experience.
