  1. Hyperledger Fabric users often use the terms smart contract and chaincode interchangeably. In general, a smart contract defines the transaction logic that controls the lifecycle of a business object contained in the world state. It is then packaged into a chaincode which is then deployed to a blockchain network. Think of smart contracts as governing transactions, whereas chaincode governs how smart contracts are packaged for deployment
  2. Smart Contracts sind ein zentraler Baustein in Blockchains. Mit Transact wollen die Hyperledger-Entwickler ihre Erfahrungen aus Sawtooth und Fabric dazu nutzen die Entwicklung von Smart Contracts zu vereinfachen und mehr Möglichkeiten für Smart Contracts zu integrieren.

Smart Contracts and Chaincode — hyperledger-fabricdocs

Ethereum, like Fabric, have multiple smart contract languages. Ethereum's are Solidity -- a JavaScript-like language, Serpent -- a Python-like language, and LLL -- a Lisp-Like Language). The big difference here is that Fabric runs the actual versions of those languages so your skills are portable in both directions In the PaperNet network, the smart contract is shared by the different network participants, such as MagnetoCorp and DigiBank. The same version of the smart contract must be used by all applications connected to the network so that they jointly implement the same shared business processes and data
