PANews reported on March 26 that according to TechCrunch, Emin Gün Sirer, founder and CEO of Ava Labs, said in an interview that many Layer 1 blockchains have emerged in the crypto ecosystem, but a large number of Layer 1 blockchains will be eliminated in three to five years from now. I think we already have too many Layer 1s, but most of them are plagiarism. In addition, Gün Sirer pointed out that Layer 1 must be decentralized, secure and fast.
