Smart contracts

Question

Are some of the compelling features in ethereum contracts adoptable to Multichain/Bitcoin. In particulary

- data and code storage at the contract level

- ability to maintain state

- ability for contracts to call other contracts

The idea is how much flexibility could be given to financial contract writers in Multichain like platform.

Answer 1

In theory, anything that Ethereum does can be performed in the bitcoin transaction model, by simply using transaction metadata to encode a language or bytecodes that provides Turing-complete computation.

Indeed the Counterparty guys have already done this for Ethereum over bitcoin:
