Ethereum (ETH) has faced the dilemma of moving to proof-of-stake in the usual way – by another delay in the mining “ice age”. For the past three years, developers have voted several times to disable the difficulty time bomb, so that miners could get some grace time to seek block rewards.
Ethereum’s Berlin Hard Fork Arrives Without Difficulty Growth
The next likely delay of the difficulty time bomb will happen for the Berlin hard fork, which is scheduled for June 2020. The Istanbul hard fork, which is expected in December 2019, will also go without the final drive to abandon mining.
Ethereum’s difficulty bomb is like the US debt ceiling. It’s a self-imposed rule that is supposed to force change, but is easily pushed back with zero penalty whenever it comes around. They should just get rid of this charade completely.

The phasing out of mining is seen as an empty promise on the side of Ethereum’s team. Despite the network problems based on the proof-of-work model, and the congestions based on gas usage, proof-of-stake for ETH will be only partial, and miners will remain important.
The latest talk of delay follows the Istanbul hard fork that caused a split of the Ropsten testnet. The event gave an interesting possibility – that despite moving on to another block production model, miners are influential enough to keep producing blocks.
There are now fears that Ethereum may end up with two competing chains. The exact resolution of the conflict is now unknown, as the rule of the longest chain can be disregarded and new assets can be produced.
