Thanks to the Web3 Foundation and Parity Technologies, Setheum could survive Post-Quantum World, WWIII, WWIV and even Zombie Apocalypse. Setheum provides reliability as a service through the development of a cluster of reliable protocols & services including but not limited to Setheum explorer, SettPay wallet and many more to come. Setheum is based on a NPoS (Nominated Proof of Stake) consensus algorithm and a Finality Algorithm called “GRANDPA”(GHOST-based Recursive Ancestor Deriving Prefix Agreement), invented by Web3 research scientist Alistair Stewart and implemented by Thiel Fellow and Polkadot cofounder Robert Habermeier. GRANDPA gives asynchronously, accountable safe finality in a hybrid consensus blockchain. Under good network conditions, GRANDPA can finalise blocks nearly instantly. Under bad network conditions, like a network partition, GRANDPA can finalise millions of blocks at once when the partitions resolve. GRANDPA can finalise a new block regardless of how many blocks have passed since the last one was finalised. GRANDPA figures out which blocks are in at least ⅔ of nodes’ chains and finalises them. It can also give different validators different weights, e.g., by the amount staked in the protocol.
