Particl’s Security Prevents Meltdown / Spectre From Affecting Proof-of-Stake Blockchain


Earlier this year, nearly every device with an Intel CPU was affected by the Meltdown and Spectre vulnerabilities. The two vulnerabilities allowed hackers and malicious actors to steal passwords and sensitive information from devices, by accessing the memory and secrets of programs on the operating system of devices. Disclosure: This is a Sponsored Article Meltdown, easier to exploit than Spectre, breaks the basic isolation between user applications and the operating system of devices, leaving memory and private data vulnerable to attacks. Spectre, more difficult to exploit but also harder to detect, allows malicious actors to trick error-free programs to leak secrets, leading sensitive data to be released. In January, Oleg Andreev, the protocol architect at blockchain company Chain, stated that proof-of-stake (PoS) is an “incompetent” idea because when major vulnerabilities like Meltdown and Spectre are exploited, private keys stored locally in memory are retrievable. When private keys are lost, attackers can easily reallocate massive amounts of funds, getting ahold of the stake and obtaining the ability to attack the PoS blockchain. “Meltdown/Spectre is why Proof-of-Stake is an incompetent idea: PoS authors ask for an unforgivable amount of money to sit in the online wallets that actively generate signatures,” said Andreev. Last month, almost immediately after Meltdown / Spectre were discovered and utilized to exploit devices, Particl introduced its Cold Staking safeguards, that prevent locally stored private keys of being vulnerable to attacks. “Particl Cold Staking safeguards your wallet’s private keys, and thus your PART, by using a script (contract) between…
