#### What is XDAG? XDAG, or Dagger Coin, is a novel [cryptocurrency](https://www.coinbase.com/learn/crypto-basics/what-is-cryptocurrency) that operates on a Directed Acyclic Graph (DAG) infrastructure. Unlike traditional [blockchain](https://www.coinbase.com/learn/crypto-basics/what-is-a-blockchain)-based cryptocurrencies, XDAG utilizes a unique model where each block is a transaction and an address. This innovative approach aims to create a decentralized payment system capable of processing thousands of transactions per second. Launched in January 2018, XDAG is a community-driven project, developed and maintained by enthusiasts worldwide. It is a mineable cryptocurrency, with no project sponsor, no [Initial Coin Offering](https://help.coinbase.com/en/coinbase/getting-started/crypto-education/altcoins-and-icos) (ICO), no private placement, and no pre-[mining](https://www.coinbase.com/learn/crypto-basics/what-is-mining), striving to be truly decentralized, efficient, and fair. #### How does XDAG work? XDAG operates on a DAG infrastructure, where each block contains exactly one transaction and simultaneously serves as an address. The network identifies a main chain within all transactions, which is a chain with the maximum difficulty. New coins are created approximately once a minute in the main chain. The network uses the ECDSA algorithm with a 256-bit [private key](https://www.coinbase.com/learn/crypto-basics/what-is-a-private-key) for a signature that confirms the rights of the [wallet](https://www.coinbase.com/learn/crypto-basics/what-is-a-crypto-wallet) owner for money in the given address. All messages are transmitted between hosts in an encrypted form, enhancing the security of transactions. XDAG's transaction model is similar to [Bitcoin](https://www.coinbase.com/learn/crypto-basics/what-is-bitcoin)'s UTXO, and the development of the project also has some similarities with Bitcoin's. #### What are the potential use cases for XDAG? XDAG aims to create a decentralized payment system that can process thousands of transactions per second, making it potentially useful for a wide range of financial applications. Its unique DAG infrastructure allows for high scalability, which could be beneficial for large-scale systems that require fast and efficient transaction processing. Additionally, the use of encryption and secure signature algorithms ensures the security of transactions, making XDAG suitable for applications that require secure financial transactions. The project also seeks to be listed on more exchanges, which could increase its accessibility and usability for a broader range of users. #### What is the history of XDAG? XDAG was launched in January 2018 as a new generation public chain based on Directed Acyclic Graph (DAG) infrastructure. It was developed and is maintained by a global community of geek enthusiasts, with no project sponsor, no ICO, no private placement, and no pre-mining. The main network was launched with the goal of creating a decentralized, efficient, secure, and fair cryptocurrency. Since its launch, XDAG has been continuously developed and improved, with various updates and enhancements made to its system. The project's roadmap outlines several future plans, including the implementation of [smart contracts](https://www.coinbase.com/learn/crypto-basics/what-is-a-smart-contract), the introduction of a fixed fee per transaction, and the exploration of cross-chain protocols.
