Stellar is an open source license for money transfer, running the client software through the server to achieve protocol operation and connecting with other stellar servers for communication, which forms a network for global value exchange.

Each server stores the record of all “stellar accounts” on the network, which are stored in a database called ledger. The server amends the ledger by making a transaction and transfers funds from one area to another by paying the balance of the account or changing the property of the account.

When stellar was just launched, XLM was based on the protocol of Ripple. However, after several times of modifications to the key consensus code, XLM network has forked. Afterwards, the co-founder of stellar, Joyce Kim claimed that this is a defect in the Ripple protocol. The Stellar Development Foundation then created a new protocol based on the new code.
