The Ethereum ecosystem has seen solely 226 validators slashed because the launch of the Beacon Chain on Dec. 1, 2020 — amounting to only 0.04% of 524,060 validators, in keeping with an Ethereum core developer.
Slashing is a course of the place a validator breaches the proof-of-stake consensus guidelines, which regularly ends in the elimination of that validator from the community and slashing a portion of the staked Ether (ETH) that the validator supplied as collateral.
Such slim odds of being slashed had been highlighted by Ethereum core developer “Superphiz” in a Feb. 23 Twitter publish, which suggests that folks shouldn’t be involved about staking ETH for that specific purpose.
226 out of 523,000 validators on the beacon chain have been slashed. That is nothing to lose sleep over. Many slashings have occurred throughout failed system migration. Listed below are 4 rising finest apply tricks to keep away from this:https://t.co/wleR4YQmDD

The developer additionally defined “4 rising finest practices” to scale back these odds even additional.
One in all these practices was to wipe any current chain information on outdated staking machines and to reinstall and reformat the validator the place obligatory, mentioned Superphiz, noting that many slashings happen because of “failed methods migrations.”
Superphiz then advised utilizing “doppelganger detection,” which checks whether or not the validator’s keys are energetic earlier than beginning the validation course of.
Whereas this could affect validator uptime, he defined that “excellent uptime” isn’t value getting slashed within the grand scheme of issues:
“It is clever to throw away $0.06 to save lots of $1700. (A slashing prices about 1 Ether).”
The developer mentioned it’s also value watching buffers and logs on the Beacon Chain to change into conscious of any potential issues which will come up.
If one thing feels unsuitable, Superphiz advised “unplugging the whole lot” and to “come again” when the issue has been recognized and a proposed answer is ready in place.
The developer additionally famous that over 150 of the 226 slashings have been brought on by companies relatively than “house stakers.”
Slashing can happen because of an “attestation” or a “proposal” violation, in keeping with the Ethereum Basis.
An attestation violation is one the place a malicious validator makes an attempt to alter the historical past of a block or “double votes” by testifying two candidates for a similar block.
A proposal violation happens when a validator proposes and indicators two totally different blocks for a similar slot.
The vast majority of slashing occasions have come from attestation violations, in accordance to information from beaconcha.in.
One of many largest slashing occasions occurred on Feb. 4, 2021, when staking infrastructure supplier “Staked” had 75 of its validators slashed for producing competing blocks. Staked mentioned the attestation violation took place because of a “technical challenge.”
Associated: What are the dangers of the Ethereum Merge?
Since the Beacon Chain merged with the Ethereum proof-of-work chain on Sept. 15, solely 35 of the entire 226 slashings have taken place, in keeping with beaconcha.in, which means that the Merge has not had a profound affect on slashing charges.
With about 16.7 million ETH staked (in keeping with beaconcha.in) out of 120.4 million ETH at the moment in circulation (in accordance to CoinGecko), the proportion of ETH staked is about 13.9%.
ETH may be staked by way of a centralized change, by delegation to a third-party validator community, or by operating on an impartial node, which requires 32 ETH.
