Stellar’s XLM stands apart from most of the other popular cryptocurrencies as it cannot be mined or staked for generating rewards. Stellar utilizes its unique consensus mechanism, the Stellar Consensus Protocol or SCP, in which the XLM coins play no role in achieving consensus. The total supply of XLM remains fixed as mentioned above, and while the SDF has burned some tokens in the past, it insists that it has no plans to do so in the future.
