 With recent Tezos upgrades heavily focusing on scaling solutions, Tezos has been at the forefront of blockchain research. Up to 1 million transactions per second (TPS) are theoretically possible on Tezos with the advent of Smart Rollups, which have emerged as a strong scaling solution. With Smart Rollups (also known as optimistic rollups), transactions can be performed more quickly and cheaply and use other VMs that “roll up” their state changes onto Tezos.
 
-[Etherlink](https://www.etherlink.com) is another exciting technology in development that will greatly enlarge the possible applications and versatility of Tezos. Etherlink builds on Smart Rollups and combines them with [DAL (Data Availability Layer)](https://research-development.nomadic-labs.com/dal-testers.html>) to provide an EVM-compatible Layer 2 solution which is truly decentralized, low-latency, and low-cost.
