# DAO 3 Layer Approach ![](img/3layers_tf.png) The threefold grid has 3 layers: - Layer 2 = ecosystem security layer - only 1 blockchain with 100 validators, secures the multiple Layer 1 networks. - Layer 1 = internet of blockchains layer - ultimate scale because of thousands (or more) of blockchains - Layer 0 = the IT capacity layer - cloud computing layer, provide compute, storage and network resources to L1 and L2 Validators play an important role in securing the ThreeFold ecosystem, a validator is a blockchain component run by independent parties who validate transactions happening on the blockchain until consensus has been achieved.
