The developer additionally defined “4 rising greatest practices” to cut back these odds even additional.

One in all these practices was to wipe any current chain knowledge on outdated staking machines and to reinstall and reformat the validator the place obligatory, stated Superphiz, noting that many slashings happen because of “failed techniques migrations.”

Superphiz then prompt utilizing “doppelganger detection” — which checks whether or not the validator’s keys are lively earlier than beginning the validation course of.

Whereas this will influence validator uptime, he defined that “good uptime” isn’t price 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 stated it is usually price watching buffers and logs on the Beacon Chain to turn out to be conscious of any potential issues which will come up.

If one thing feels flawed, Superphiz prompt “unplugging every part” and to “come again” when the issue has been recognized and a proposed resolution is about in place.

The developer additionally famous that over 150 of the 226 slashings have been attributable to companies moderately than “residence stakers.”

Slashing can happen because of an “attestation” or a “proposal” violation, in response to the Ethereum Basis.

An attestation violation is one the place a malicious validator makes an attempt to vary 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 completely different blocks for a similar slot.

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 whole 226 slashings have taken place, in response to, which means that the Merge has not had a profound influence on slashing charges.

With about 16.7 million ETH staked (in response to 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 on a centralized alternate, be delegated to an third-party validator community or be run on an impartial node, which requires 32 ETH.
