Tipsets - A closer look at Filecoin building blocks
GHOSTy protocols enable miners to refer back to all observed blocks from the past in order to lend their chain weight. Filecoin’s consensus mechanism is built on a variation of this called tipsets. If Bitcoin operates like a race to produce the longest and most valid chain, Filecoin’s Expected Consensus is election-based and multiple miners can be elected as leaders in a given round. This in turn means multiple valid sibling blocks can be created per round. With each epoch, a new generation of a family tree can grow, called a tipset, a system unique to our network.
