Rumors of the dying of the Medalla testnet have been enormously exaggerated says Prysmatic Labs’ editor Raul Jordan, who provides that regardless of the mishap, the launch timetable for ETH 2.Zero stays on observe.
Medalla — the ultimate multi shopper testnet earlier than ETH 2.0’s section Zero launch — got here to a shuddering halt on August 14 when a bug took a lot of the testnet’s validators offline.
The incident noticed one of many testnet’s six servers report the time and date as being in the future into the long run, which the system responded to by averaging out the discrepancy — ensuing within the time stored 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 stated. The bug affected everybody utilizing the Prysm shopper, which the bulk had been.
In a brand new weblog entry, Jordan stated 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 serious catastrophe that proved “Ethereum 2.Zero isn’t able to launch … you possibly can count on vital delays within the launch of ETH 2.0.” Any delay can be a serious problem for the Ethereum community which is scuffling with congestion and report excessive charges.
Simply think about a bug like this bringing down mainnet. ETH 2.Zero goes to want 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 supplied “the best studying expertise to forestall 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 may be off, noting that “dynamically adjusting their time based mostly on the responses of those servers was a pleasant factor to do, however this was not obligatory in any respect and as a substitute was problematic.”
He stated they now comprehend it was a safety danger to have a single level of failure for one thing so important and to any extent further they may “depend on system time solely.”
Jordan stated claims the testnet was “lifeless” had been incorrect and stated so long as sufficient validators get again on board the testnet may return to being full operation. On Aug. 19 he stated:
“We nonetheless have hope. Participation has now climbed from 0–5% to 40%. The chain wants > 66% to finalize.”

Medalla is saved!

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