ETH 2.0's ($ETH) development should be contextualized within the youthfulness of the market, according to Raul Johnson. ETH 2.0 is built upon design decisions from the beginning of the protocol, particularly Proof-of-Stake's 'weak subjectivity' which forces new nodes to trust old nodes for chain verification. The possible cartelization of the PoS network is the largest concern facing ETH 2.0 today. Upgradability is a core feature of ETH 2.0 and if ETH 3.0 is needed, the whole project has been in vain.
