Major ones that pre-date Ethereum:

  • BitShares
  • OMNI (formerly known as Mastercoin)
  • NXT
  • Counterparty (uses the Bitcoin blockchain)

An upcoming one I'm aware of: Rootstock

    what are the differences and why are they competing. what do they have in common? please try to add some details to your answer. – q9f Feb 02 '16 at 00:56
  • @acros: OP specifically asked about smart contracts, hence the "programmable" blockchain. Can you, as a dev, write smart contracts in Bitshares and OMNI/MasterCoin? Seen that Rootstock.io is basically a port of Ethereum to Bitcoin, I agree with Rootstock. But I'm really not sure BTS and OMNI/MasterCoin qualify as "programmable blockchains" / smart contracts / whatever you want to call that. – Cedric Martin Feb 02 '16 at 17:10
