Stellar (XLM) Cryptocurrency and Blockchain Guide


What is Stellar (XLM)?

Stellar is an open-source payment transfer ecosystem that uses blockchain technology with its XLM cryptocurrency token.

Lumen was originally named “Stellar” with 100 billion coins launched globally in 2014. It was then renamed to Lumen after the network was upgraded in 2015 to distinguish itself from the Stellar network. There is a minimum balance requirement of 0.5 lumens for all XLM accounts to encourage users to remove unused or unnecessary accounts from the ledger.


Stellar does not allow the public to operate nodes, the developers run their own nodes currently using multiple servers. Private organizations and banks may run nodes if they decided to get into a partnership with Stellar and use their blockchain technology.

Native Coin

The native cryptocurrency coin of Stellar is Lumen (XLM), built on the same network and can be kept, traded or used as an asset by its users to swiftly transfer money or conduct transactions globally between different currencies securely.


Steller does not use miners. The supply of Lumen coins is controlled by the developers and set by fixed protocol level rules, with a 1% annual inflation rate. No one except the Stellar team can create new lumen coins arbitrarily but they can submit a proposal to change the rule and protocol for creation of Lumen coins, subject to the acceptance of the validators on the Stellar network. There is a total of 100 billion Lumens launched but only around 20 billion coins are in market circulation as of April 2019. Hence, some critics criticized Stellar for being too centralized.


Lumens are used on the XLM network for prioritization and prevent malicious spamming and overloading of the network. There is a fee of 0.00001 lumens for every transaction, around $1 USD for 400,000 transactions as of April 2018. The fee for one transaction is very small, but for anyone trying to generate huge number of transactions via a Denial of Service (DoS) attack, they will have to pay considerable amount of lumens. Hence, the fee mechanism is a deterrence to counter malicious attackers.


Lumens can be used as a bridge currency between pairs of currencies where there is no direct market. Hence, Lumens and its Stellar platform conveniently connect people, payment systems and banks quickly. XLM transaction settlement time are reported to be 5 seconds on average.

1000 TPS is 60 times faster than Ethereum but Stellar is unable to develop complex Dapps as much as Eth.
