BLOCKCHAIN ARCHITECTURE

Immutable: no party will be able to change the contract once it is fixed and written to the public ledger(the blockchain)
Distributed: all the steps of the contract can be validated by every participating party-no one can claim later that the contract was not validated
Why blockchain?
The blocks are immutable
The information is open-everyone can check and validate
So, the advantage of this kind of smart contract is first of all they are immutable; that means, no party will be able to change the contract once it is fixed and return to the public ledger like blockchain.

Next, it is distributed you do not need a middleman like this to say Kickstarter who is handling all the risk.

your code will be automatically get executed and if you are not fulfilling your promise then automatically the code will execute some steps based on the contracts.

And why the blockchain? Why blockchain is a suitable platform for the executable smart contract? Because first based on the blockchain architecture, the blocks are immutable and the second the information is open, everyone can check and validate the information inside a blockchain READ MORE
