Smart Contracts The transactions of e.g. Ethereum have a fixed order becaue they are in a blockchain. Because IOTA stores it's transactions in the Tangle, we don't have a sequence. In order to execute smart contract consistency is required. To achieve something similar on IOTA, mandatory timestamps are necessary. Mandatory timestamps You can already send ...

Qubic is the name of a protocol which will be built on top of the IOTA Tangle. The Qubic protocol provides general-purpose, cloud- or fog-based, permissionless, multiprocessing capabilities on the Tangle. It does this by allowing the transfer of prepackaged computational tasks from a device to some assembly of oracle machines, and have them perform said ...

Ales has his own take, but I think he is perhaps ruling out smart contracts based on perceived functionality from other implementations. http://iota.org/timestamps.pdf Even if all transactions have timestamps on them, we cannot be sure that all these timestamps are accurate (there can be some malicious nodes that want to fool the network about the ...

In IOTA timestamp accuracy cannot be trusted. "The tangle is a graph with only a partial order structure, which makes it difficult (in fact, generally impossible) to establish the correct time order of transactions. Even if all transactions have timestamps on them, we cannot be sure that all these timestamps are accurate" Source: http://iota.org/...

One main difference in the language: Abra is a functional language (source : "Qubic tasks are specified using an intermediate trinary-based functional programming language called Abra.") and Solidity (main language for Ethereum smart contract) is a classical procedural language. Writing a formal proof (i.e. a mathematical proof) that a program is correct is ...

IOTA will use a smart contract language called Abra - which is an intermediate trinary-based functional programming language. More information on Abra can be found here.
