In particular, Hoskinson drew attention to the Gasper finality protocol used in Ethereum 2.0.<\/p>\n<p>Referencing a Stanford University research paper titled &#8220;<a href=\"https:\/\/arxiv.org\/pdf\/2009.04987.pdf\">Ebb-and-Flow Protocols: A Resolution of the Availability-Finality Dilemma<\/a>,&#8221; Hoskinson requested Buterin&#8217;s response to the findings.<\/p>\n<blockquote class=\"twitter-tweet\" data-width=\"500\" data-dnt=\"true\">\n<p lang=\"en\" dir=\"ltr\">Great paper and difficult security questions for Ethereum 2 to address.

In other words, once a transaction reaches finality no-one can change, reverse, or cancel it.<\/p>\n<p>All cryptocurrency ledgers go through a process of the finalized ledger lagging the full ledger until network partitions catch up. The latency level of a chain will affect the chain&#8217;s finality rate and vice versa.<\/p>\n<p>However, researchers simulated an attack on the Gasper protocol and discovered it was insecure under standard conditions.<\/p>\n<blockquote>\n<p>&#8220;However, we discovered an attack in the standard synchronous network model, highlighting a general difficulty with existing finality-gadget-based designs.&#8221;<\/p>\n<\/blockquote>\n<p><a href=\"https:\/\/twitter.com\/IOHK_Charles\/status\/1306259325002842112\">Hoskinson<\/a> clarified the findings by saying, under Gasper, it&#8217;s possible for attackers to delay the syncing process between the finalized ledger and the full ledger. Meaning, an attacker could potentially change, reverse, or cancel a transaction during that extended latency period.<\/p>\n<blockquote>\n<p>&#8220;<span class=\"css-901oao css-16my406 r-1qd0xha r-ad9z0x r-bcqeeo r-qvutc0\">In particular, we discovered a liveness attack on Gasper in the standard synchronous model where messages can be delayed arbitrarily by the adversary up to a known network delay bound&#8230;.<\/span>&#8220;<\/p>\n<\/blockquote>\n<p>Buterin has yet to respond to the claims.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Phase 0 of Ethereum 2.0 took a step forward today following the submission of EIP 2982.
