PANews reported on May 21 that Yves La Rose, founder and CEO of the EOS Network Foundation, published an open letter on Twitter, aiming to take measures to make Block.one (B1) fulfill its investment commitment to the EOS network. The two feasible options are: 1. Take legal action against Block.one. If enough token holders file legal claims, the EOS Network Foundation can file a claim against Block.one. 2. Hard fork. Block producers can consider using a hard fork to prohibit tokens owned by Block.one from participating in EOS token transactions, which will cut off all connections between EOS and B1 and reduce the supply of EOS tokens. It is reported that Block.One promised to invest $1 billion in the EOS network in 2018.
