WebApr 25, 2024 · Hence, the Institution communicates through DEXON’s fair cryptographic sortition to achieve decentralization. DEXON applies a VRF-based sortition algorithm to select a subset of nodes as block producers, allowing DEXON to scale to a large number of nodes, making the whole system fully decentralized. WebCryptographic sortition allows the network to compute, without communication, which node will do what, at what step, and guarantees none of this is even observable to an attacker until it is done. The network is essentially a hive mind. This is called player replacability.
