Vitalik: The quality of the underlying proof system of L2 networks is equally important and should gradually enter the second stage as it develops

ChainCatcher news, in response to community member Daniel Wang's proposed naming label #BattleTested for the L2 network Stage 2, Ethereum co-founder Vitalik posted on the X platform stating: "This is a good reminder: the second stage is not the only factor affecting security; the quality of the underlying proof system is equally important. This is a simplified mathematical model that shows when to enter the second stage:Each security council member has a 10% independent 'break' chance; we consider activity failure (refusal to sign or key unavailability) and security failure (signing the wrong thing or key being hacked) as equally likely; the goal: to minimize the likelihood of protocol collapse under the above assumptions.Stage 0 security council is 4/7, Stage 1 is 6/8; please note that these assumptions are very imperfect. In reality, council members have 'common mode failures': they may collude, or all be coerced or hacked in the same way, etc. This makes both Stage 0 and Stage 1 more insecure than shown in the model, so entering Stage 2 earlier than the model suggests is the best choice.Additionally, note that by turning the proof system itself into multiple independent systems via multi-signature, the probability of proof system collapse can be greatly reduced (this is what I advocated in previous proposals). I suspect that all Stage 2 deployments in the past few years will be like this. Considering this, here is the chart. The X-axis is the probability of proof system collapse. The Y-axis is the probability of protocol collapse. As the quality of the proof system improves, the optimal stage shifts from Stage 0 to Stage 1, and then from Stage 1 to Stage 2. Using a proof system of Stage 0 quality for Stage 2 is the worst.In short, @l2beat ideally should showcase proof system audits and maturity metrics (preferably proof system implementations rather than the entire aggregation, so we can reuse them) and stages."

KuCoin launches the "Trust Plan": commits to invest $2 billion to comprehensively upgrade platform transparency, security, compliance system, and KCS ecosystem

ChainCatcher news, at the global crypto event TOKEN2049 in Dubai, cryptocurrency exchange KuCoin officially launched its major strategy------the "Trust Plan," and announced a future investment of $2 billion to promote KuCoin into a new stage of high-quality, sustainable development, focusing on key areas such as platform security, transparency building, compliance system enhancement, and KCS ecosystem development.It is reported that this conference marks the first public appearance of KuCoin's new CEO BC Wong since taking office. He took the stage alongside KuCoin's EU CEO Oliver Stauber, addressing over 15,000 industry leaders, regulatory representatives, and crypto innovators from around the world, elaborating on KuCoin's long-term vision and systematic layout regarding the core industry proposition of "trust."In his speech titled "The Trust Gap in the Crypto Industry: Building a Winning Platform," BC Wong pointed out: "As the crypto industry enters the mainstream era, technology and speed are merely entry thresholds. Platforms that can truly transcend cycles must continuously invest in underlying values such as security, transparency, compliance, and responsibility." He stated that the "Trust Plan" is not only a significant financial commitment but also a comprehensive realization of KuCoin's core values. In the coming years, KuCoin will continue to strengthen platform security infrastructure, promote on-chain transparency mechanisms, deepen collaboration with global regulatory agencies, and increase investment in user education and ecosystem health, fully constructing a more trustworthy digital asset trading environment.Among them, KCS (KuCoin Token), as the core connecting asset between the platform and users, will play a crucial role in the "Trust Plan." KuCoin will further optimize the incentive mechanisms, governance rights, and ecological applications of KCS, strengthening its strategic position in enhancing user stickiness, participating in governance, and promoting community co-construction.
