After Solana’s DDoS attack, crypto watchers cast doubt on Proof-of-History

Issues seem like again to enterprise for Solana, after the fifth largest blockchain suffered a distributed denial-of-service (DDoS) assault that jammed the community and led to delays throughout.

However since then, some crypto customers have been attempting to research the basis reason for the assault and whether or not it might occur to different chains. In reality, even Polkadot retweeted a dialog associated to the safety of its personal chain.

Poking at Solana

Issues got here to a head when the CIO of an funding agency pointed a finger at Solana’s Proof-of-Historical past consensus mechanism.

For his half, Justin Bons tweeted,

“…Solana was DDoS attacked once more yesterday This assault exploited elementary design flaws that are thought-about options by SOL Because it sacrifices decentralization & safety for pace Whereas ignoring the results of that commerce off Particularly Proof of Historical past & Turbine…”

The put up shortly went viral as many tried to know whether or not Proof-of-Historical past may very well be a safety threat. To refresh your reminiscence, this consensus mechanism addresses the issue of system clocks which may not be synchronized. In PoH, Solana validators clock events independently to construct up a sequence of when occasions occurred – thus saving time.

Join the dots

Right here’s the place Polkadot is available in. The blockchain’s official Twitter account retweeted Parity Technologies core developer Shawn Tabrizi, who in contrast PoH to Polkadot’s Blind Project for Blockchain Extension [BABE] mechanism. BABE is an algorithm the place main leaders for various time intervals, or slots, are chosen randomly for extra safety. There can be secondary slot leaders.

Readers may be fast to dismiss Twitter customers’ opinions. Nonetheless, it’s not simply crypto watchers who’re involved. Grayscale Investments too, in its introduction to Solana, flagged the blockchain’s consensus mechanism as a possible threat.
Grayscale Investments’ report noted,

“The Solana consensus mechanism makes use of a brand new blockchain know-how that’s not broadly used, and should not operate as meant. There could also be flaws within the cryptography underlying the community, together with flaws that have an effect on the performance of the Solana Community or make the community susceptible to assault.”
