# About TRON blockchain The TRON blockchain has been around since 2017 and started out as an ERC20 token and has evolved to be the top blockchain with the highest amount of stablecoin transaction volume of all blockchains. With the growth of stablecoin transactions, the TRON community and holders get rewarded directly and indirectly so value accrues to the token $TRX and hence its holders\ \ Before one can understand the value of $TRX tokens, one needs to understand the unique mechanisms that come with the underlying TRON blockchain. ### Proof of Stake The TRON blockchain consensus mechanism is Delegated Proof of Stake (DPoS). That means token holders can vote a Super Representative (SR) that runs nodes that validates transactions for the network and contribute to network security. In TRON ,there are 27 Super Respresentatives. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
