I thought ethereum has reach his limit of development? or there is another implementation about it? just the adding the TPS ? or it was the same as always.
It has not, vitalik and core developer of etheruem platform have created so many partnerships and he said that the next update for ethereum platform is on the way and this can be considered as a big update that will be conducted at the next year. It's confirmed by him.
They Delayed that coz the government wants to use their platform. That's why the next update will be the end of this year. I think Casper Protocol will be release a proof of stake algorithm.
