Rumors of the dying of the Medalla testnet have been drastically exaggerated says Prysmatic Labs’ editor Raul Jordan, who provides that regardless of the mishap, the launch timetable for ETH 2.Zero stays on monitor.
Medalla — the ultimate multi consumer testnet earlier than ETH 2.0’s part Zero launch — got here to a shuddering halt on August 14 when a bug took many of the testnet’s validators offline.
The incident noticed one of many testnet’s six servers report the time and date as being at some point into the longer term, which the system responded to by averaging out the discrepancy — ensuing within the time saved by every of the servers being unsuitable by 4 hours.
As a consequence, “validators incorrectly proposed blocks and attestations for future slots,” Prysmatic’s official incident report mentioned. The bug affected everybody utilizing the Prysm consumer, which the bulk have been.
In a brand new weblog entry, Jordan mentioned the results of the bug was “carnage, with over 3000 slashing occasions… and all our inner validators slashed.” Whereas he described the failure as “the perfect factor to occur to a testnet” because the incident would have been catastrophic on mainnet with actual cash at stake, proponents of competing networks have gleefully seized on the failure.
Bitcoin SV weblog CoinGeek reported it as a significant catastrophe that proved “Ethereum 2.Zero isn’t able to launch … you possibly can count on important delays within the launch of ETH 2.0.” Any delay can be a significant difficulty for the Ethereum community which is fighting congestion and report excessive charges.
Simply think about a bug like this bringing down mainnet. ETH 2.Zero goes to wish all of the testing it could actually get. Possibly a few Hail Mary’s too. 18 months TM. https://t.co/6e1oQ7uVYu

‘An eventful weekend’
Jordan performed down the problems, calling it “an eventful weekend” that provided “the best studying expertise to stop this taking place once more, particularly on mainnet.”
He defined the issue resulted from Prysmatic utilizing roughtime cloud servers to present customers suggestions that their system time is perhaps off, noting that “dynamically adjusting their time primarily based on the responses of those servers was a pleasant factor to do, however this was not needed in any respect and as a substitute was problematic.”
He mentioned they now comprehend it was a safety threat to have a single level of failure for one thing so important and any more they are going to “depend on system time solely.”
Jordan mentioned claims the testnet was “useless” have been incorrect and mentioned so long as sufficient validators get again on board the testnet might return to being full operation. On Aug. 19 he mentioned:
“We nonetheless have hope. Participation has now climbed from 0–5% to 40%. The chain wants > 66% to finalize.”
Earlier at present Prysmatic Labs retweeted the next:
Medalla is saved!

Jordan mentioned that Prysmatic Labs believes the incident “doesn’t inherently have an effect on the launch date” of ETH 2.Zero and that the part Zero launch can proceed as deliberate:
“We consider the anticipated launch goal of two to three months from Medalla genesis remains to be a great timeline. There can be a public guidelines of necessities for an ETH2 launch, and this Medalla incident will certainly add a number of new objects to the record concerning consumer resilience, safety, and correct launch.”
