The so-called 'The Merge' is the moment when the current Ethereum mainnet "merges" with the beacon chain proof-of-stake (PoS) system, slated for late 2021 at the earliest. Therefore, the network’s consensus mechanism will transition away from the current proof-of-work (PoW), used by Bitcoin also, to PoS. However, the 'eth' hashtag which directly had nothing to do with Ethereum seemingly garnered far more interest on social media than this important EIP-3675. Even the official Olympics account commented on this, stating that "great to see Jack [Dorsey, CEO of Twitter] and the crypto community supporting the #ETH [Ethiopian flag] athletes!" Many are questioning whether Dorsey is trolling the Ethereum community.
