Foreign media: ETH 1.0 developers risk delaying ETH 2.0

ETH 1.0 developers suddenly claimed that ETH 2.0 must wait for them to join the upgrade of BLS signatures to verify malformed deposits. ETH 1 hard fork coordinator James Hancock said that we hope that the Berlin hard fork will be released before the deposit contract is released so that BLS Precompile can be used. Hancock said that the deposit contract should not be released before the Berlin hard fork, but we have the flexibility to decide when to support the ETH 2 roadmap. An anonymous ETH 2 researcher said that the ETH 1 BLS upgrade was unnecessary. It's unclear exactly what the "official" plan is, but sources have previously said that the deposit contract is expected to be completed in April. ETH 1 and ETH 2 are different teams, so there may be some confusion.
