In September 2022, Ethereum is scheduled to start ETH 2.0's Merge upgrade. Some exchanges will support its potential hard fork. If successful, the Merge could create two parallel blockchains after the upgrade. Prior to the official ETH 2.0 upgrade, ETH holders on a few exchanges can swap their ETH into two "potential forked" tokens, ETHPoS \[IOU\] and ETHPoW \[IOU\], at a 1:1 ratio. "Potential forked" token explained: ETHPOS (Ethereum PoS) represents the token for the new PoS (proof-of-stake) chain; [ETHPOW](https://www.cryptocompare.com/coins/ethpow/overview) (Ethereum PoW) represents the token for the PoW (proof-of-work) chain that will potentially continue to exist.
