TON (The Open Network) is a layer-1 blockchain originally developed by Telegram, abandoned in 2020 following an SEC enforcement action that compelled a $18.5 million penalty and $1.22 billion investor return, and subsequently revived by an independent TON Foundation. By 2024, rapid ecosystem growth attracted a significant wave of phishing campaigns, wallet drainer toolkits, pyramid schemes, and rug pull activity, with over 1,200 fraud cases reported in H1 2024 alone. In May 2026, Pavel Durov announced Telegram would reassume control as the network's largest validator, reintroducing centralization risk to a network already under scrutiny for facilitating illicit marketplaces.

Sui is a Layer 1 blockchain developed by Mysten Labs, launched in May 2023 and built on the Move programming language. The network suffered one of the largest DeFi exploits of 2025 when Cetus Protocol — its primary DEX — was drained of approximately $223 million in May 2025, triggering a controversial emergency validator vote to freeze and reclaim stolen funds that exposed deep centralization concerns. Separately, ZachXBT investigated a $29 million SUI token theft in late 2024 involving Tornado Cash laundering and subsequently announced in July 2025 that he would no longer take Sui ecosystem cases due to inadequate incident-response infrastructure and lack of support from the ecosystem.
