Telegram CEO Pavel Durov said TON (The Open Network, a blockchain platform) is "one of the most decentralized blockchain networks on the planet." He added that Telegram becoming the largest validator (network transaction confirmer) opened the door for major exchanges and custodians (institutional crypto asset safekeepers) to stake TON (locking crypto to help secure the network and earn rewards) without increasing centralization risk. The statement addresses a common concern in proof-of-stake networks, where a large concentration of validation power can raise questions about network control.
