what are the relations between namecoin and blockstack?https://www.namecoin.org/docs/faq/#how-does-namecoin-compare-to-blockstack
Note that that FAQ section is pending an update, but it's mostly still accurate.
it seems that blockstack implements a new internet system based on namecoin ?
Blockstack isn't an Internet system, it's a naming system. Blockstack seems to be betting that the general public is too uninformed to figure out that their claims of being "an Internet" are bullshit. Which, to be honest, might be a safe bet.
edit: seems pretty quiet here.
