satoshi didn't creat blockchain, because blockchain was created 17 years before Bitcoin was born. and with name Time-stamp. time-stamp was created in 1991 by Stuart Haber and W. Scott Stornetta. but not adopted en masse. because it has a common problem of byzantium. and in 2008 satoshi solved this problem with alternative solutions. namely through proof-of-work created by Satoshi, then Bitcoin was born as a verification tool on the blockchain. so make no mistake. satoshi is not creator of the blockchain. but only perfecting time-stamps (now blockchain) that have common problems and solve them with bitcoin.
