I have a full GETH node running and looks like Ethereum 2.0 is about to release. My question is:

  • Will I need to do tweak anything in my node once Ethereum 2.0 releases?
  • Will my GETH full node be able to use Mainnet for transactions in Ethereum 2.0?

Only the phase 0 of Eth2 is about to release. And that also will only launch a public common testnet, nothing more. So there is no real hurry with anything.

In any case when the real Eth2.0 launches (after a year or two) you probably have to decide yourself whether you want to continue mining 1.0 chain (which will be active at least for some time) or consider starting as a validator in 2.0 chain where the rules are completely different.

In any case there is no way for your node to "accidentally" end up as a validator in Eth2.0.

For a developer the changes are probably not very big. Some semantics will possibly change a bit (possibly stuff like block.timestamp or so) but mostly I think there shouldn't be big differences.

  • Isnt the phase 1 release of beacon chain part of the mainnet? Also I am not a miner but just a developer. What changes would I need to do to use Ethereum 2.0 in GETH once it releases? – Subik Aug 4 '20 at 6:15
  • beacon chain release is phase 0. And its release is not going to mainnet yet (as there is no mainnet for 2.0 yet). Edited answer to add info for developer – Lauri Peltonen Aug 4 '20 at 6:20
  • So, all the phases(0,1,1.5,2) will be release on test net. And then only on mainnet?? – Subik Aug 4 '20 at 6:49

    Yes, first they are tested in testnets. For example the phase0 has been in half-private testnets for half a year now and is supposed to be released to a public common testnet today – Lauri Peltonen Aug 4 '20 at 6:51
