Where does the stellar smart contracts stored. Its storing in blokchain (similar like ethereum) or its runs separately and storing only the signed transactions?. As i know stellar stores only the transactions in ledger so where the contracts stored.
A Stellar Smart Contract (SSC) is expressed as compositions of transactions that are connected and executed using various constraints
SSCs are not stored as executable contracts. They are formed as the logical outcome of constraints placed around transactions.
The constraints available include:
Multisignature - What keys are needed to authorize a certain operation? What parties need to agree on a circumstance in order to execute the steps?
Batching/Atomicity - What operations must all occur together or fail? What must happen in order to force this to fail or pass?
Sequence - In what order should a series of transactions be processed? What are the limitations and dependencies?
Time Bounds - When can a transaction be processed?
