Ledger: Advantages of Blockchain Smartcontract - Articles

Autonomy: The benefit of blockchain smartcontract is that they are decentralized in nature. They are direct dealings between parties and do not require the involvement of any third party in the process. This allows smartcontract to be transparent.

Accuracy: Smartcontracts are based on the requirement that all the terms and conditions are recorded explicitly.

Transparency: The Smartcontract build trust and transparency between two parties by using blockchain technology that it minimizes the dispute cases to zero. The possibility of a disagreement is avoided by the certainty and lack of between-the-lines terms in a smartcontract.

Record keeping: The blockchain stores all smartcontract transactions in chronological order and makes them accessible, along with the full audit trail. To provide complete secrecy, the parties involved can be safeguarded cryptographically.

Fraud-less: Identification and decrease of fraudulent activities. The blockchain stores smart contracts. It is extremely difficult to forcefully alter the blockchain since it requires a lot of compute. A smartcontract breach can also be discovered by network nodes, and in that case, the attempt is flagged as invalid and not recorded in the blockchain.

Fault-tolerance: Because no single person or organisation controls the digital assets, one-party dominance and situations in which one part pulls out do not occur. Additionally, because the platform is decentralised, the contract is still in place even if one node disconnects from the network.

Increased trust: Smartcontracts are automatically carried out and upheld. These agreements are also unchangeable, unbreakable, and incontrovertible since they are immutable.

Cost-efficiency: The use of smartcontracts reduces expenses by doing away with the necessity for middlemen (brokers, attorneys, notaries, witnesses, etc.). reduces paperwork as well, saving money and producing less waste.

Ledger: Features of Blockchain Smartcontract - Article

 

Distributed Ledger Smartcontracts:

These are very simple programs with conditions in it, stored on blockchain to run till the condition is met. This digital program used to automate the execution of an agreement between the parties allowing them to perform successful transactions without any involvement of central authority / agency. 

While I was checking through the Internet on the Features of Smartcontract, I have come across below list of points and they are unique in a way based on my understanding when compared with smartcontracts controlled central governing authority / agency.

Below are the few of the Features of Ledger Smartcontracts:

Immutable: Once deployed smart contract cannot be changed, it can only be removed as long as the functionality is implemented previously.

Distributed: Everyone on the network is guaranteed to have a copy of all the conditions of the smart contract and they cannot be changed by one of the parties. A smart contract is replicated and distributed by all the nodes connected to the network.

Transparent: Smart contracts are always stored on a public distributed ledger called blockchain due to which the code is visible to everyone, whether or not they are participants in the smart contract.

Secure: Smart contracts can only perform functions for which they are designed only when the required conditions are met. The final outcome will not vary, no matter who executes the smart contract.

Some of the other Characteristics of ledger smartcontract:

Autonomy: There is no third party involved. The contract is made by you and shared between the parties. No intermediaries are involved which minimizes bullying and grants full authority to the dealing parties. Also, the smart contract is maintained and executed by all the nodes on the network, thus removing all the controlling power from any one party’s hand.

Customizable: Smart contracts have the ability for modification or we can say customization before being launched to do what the user wants it to do. 

Trustless: These are not required by third parties to verify the integrity of the process or to check whether the required conditions are met.

Self-verifying: These are self-verifying due to automated possibilities.

Self-enforcing: These are self-enforcing when the conditions and rules are met at all stages.

These features alone are not making Smartcontracts unique in the blockchain technology, Features along with Capabilities are main backbone for the distributed smartcontracts. I have posted an article on Capabilities for more information - "Ledger: Capabilities of Blockchain Smartcontract - Article "
