• Fuel V1 was launched as the first optimistic rollup, but the total value locked on it is rather low. Fuel team is planning to launch an innovative V2 in accordance with some proposals. 
  • Fuel distinguishes itself as a modular execution layer among many scaling solutions. 
  • Fuel’s innovation is to offer a structure allowing parallel transactions utilizing the UTXO model instead of Account model. 
  • To enable this, they developed FuelVM where smart contracts can be executed using the UTXO model. 
  • Sway programming language allowing the development of smart contracts compatible with FuelVM was also designed by Fuel Labs.
