Defi. This drives adoption because money is involved The missing pieces are (I guess), easy call to other contracts (your medium isn't implemented ?), integration with wallets, and something like cryptozombie (so better training)

"00E097B2AF23844302 OP_2 OP_DIV OP_2" The puzzle is "give me A and B such that A*B=00E097B2AF23844302 but with A!=1 and B!=1". So I tried to divide myself 00E097B2AF23844302 but letting the unlocking script doing the division is ok too I guess.

So it would be like, if stack is a b OP_1 ; so right now the stack is a b c, with c=1 ;-- OP_1 OP_PICK ; a b c b OP_0 OP_EQUAL ; a b c (b==0) OP_IF OP_DUP OP_RETURN ; wtf ???? scrypt.studio is burning my top stack when I op_return within an OP_IF OP_ELSE ; a b c OP_2 OP_PICK ; a b c a OP_MUL ; a b (c*a) OP_1 OP_PICK ; a b (c*a) b OP_1SUB ; a b (c*a) (b-1) OP_ROT OP_ROT ; a (b-1) b (c*a) OP_NIP ; a (b-1) (c*a) OP_ENDIF ;-- Copy that 10 times.. Could be better (fast exponentiation, b>0 is not us

From what I understood R-puzzle are an UTXO you can spend if you know a specific value R. How is it different from something like "OP_HASH value" where value is hash(R) ? So you would need to know R to spend that UTXO

I'm a bit late but https://tornado.cash is cool If bitcoin is turing complete it means you could build that inside an UXTO. Anyone could deposit/withdram money to that UXTO and pay eachothers with that UXTO (meaning that when I pay someone the money won't leave the UXTO). I'm not sure if that's possible. But if it is, it's insane

Is it correct that because not everything is on this list you can change some data of the transaction without invalidating the signature, and therefore comes transaction malleability ?
