Ethereum 2.0 Dry Run Finalizes


Ethereum dry run Spadina finalizes, Sep 2020

Spadina, a three days testnet intended to practice the launch of ethereum 2.0, has finalized and now seems to be running fine.

After a dicey start, in part due to many who had deposited forgetting about it but also due to a small client bug, the network now seems to be in a good state.

This quick finalization is quite different from the last time we saw a testnet not finalizing when it crashed back in August.

Back then it took a week to get it back up and running. This time it took just 13 hours and even that was mainly because people have deposited worthless testnet eths, so they don’t have a massive incentive to do prompt validation.

That suggests the dry run has gone a lot better than might have initially been thought because it illustrates finalization can be quickly reached after low participation.

This will continue running now with Danny Ryan, the ethereum 2.0 coordinator, asking validators to keep running for the next 24 to 36 hours “just so we can observe for a day.”

There will be another dry run according to Ryan, but if the main problem was indeed people not caring to validate because of worthless testnet eth, Ryan suggests ignoring that part to focus on everything else, stating:

“In response to these issues, we’ll be hosting -at least- one more dress rehearsal — Zinken — prior to genesis.

I personally won’t consider low participation on Zinken a failure. Instead, I’m primarily looking for a clean client release process and minimal headaches for users.”

The second dry run will be on the 5th of October, leaving plenty of time for a November launch with devs presumably reporting soon on how Spadina went.

If a situation of non-finalization repeats in the live network, then eth depositors will be losing money due to the slashing mechanism.

That means a situation of non-finalization has to be avoided in any and all ways possible, which is a difficult task because bugs can be unavoidable.

Rewards for early stakers are very high however, as much as 37% when it’s only 500,000 eth staking. Thus presumably there will be plenty willing to pay the potential cost.
