A smart contract is a set of computer codes that run on top
of the blockchain stack. These codes constitute a set of terms pre-agreed upon
by all the involved parties, and when the pre-defined terms are met, the
agreement is automatically executed per the underlying business logic.
Smart Contract Characteristics:
A smart contract relies upon information obtained from an
internal source i.e. databases/ledgers of involved parties and/or external
sources, where the required input is fed with the help of oracles to execute it
on the digital platforms.
The key stated characteristics of a smart contract are:
• Self-verifying
• Self-executing
• Tamperproof
Let us now understand the process of creating a smart
contract:
1. Defining the Smart Contract:
In this initial step, we want to characterize the
understanding in its degree and build up the terms of arrangement by all
partners.
Then, at that point, we recognize every one of the gatherings
engaged with the execution of the agreement and decide the agreement technique.
Additionally, future savvy code overhauling/change situations ought to be
conceptualized so the design ought to set up an extension for those
circumstances.
2. Smart contract design:
- The next step is designing the contract. We start by
determining the events which have the potential to trigger the implementation
of the contract
- Examine if any inputs are impacting the execution
feasibility
- Identify the limitation(s) of the underlying blockchain
platform
- Define the data elements
3. Coding the business logic:
A bunch of codes is created and tried to address the expected
business contract. Likewise, the convention for informing and secure validation
is set up between the gatherings associated with the agreement.
4. Execution:
The terms of the contracts determine the flow of value. The
output is stored on an immutable blockchain ledger.
5. Updating the network:
Once the contract gets executed, every ledger node gets
updated with the newly acquired state. Any new update can only be appended.
Most important key design principles for smart contracts:
The drafting of the beneath plan standards has been finished
utilizing Ethereum brilliant agreements as the base. In any case, a large
portion of the standards are substantial for creating shrewd agreements on any
blockchain motor:
1. Simple and coherent smart contract code
2. Keep only the necessary data in the smart contract
3. Avoid gas costly patterns
4. Expect and prepare for failure
5. Oracle-ize the smart contract
6. Design for re-entrance attack
7. Design for denial of service (DoS) attack
8. Timestamps are imprecise on a blockchain and can be
influenced
9. Appropriate data types selection
10. Understand the visibility modifier for data
11. Use secure hashing for protecting data
12. Use of Access Modifiers
Smart contracts have empowered us to foster new plans of
action and encourage business connections based on innovation-based trust. In
light of blockchain innovation, brilliant agreements intrinsically offer
changelessness, security, and straightforwardness which separates them from
customary agreements, giving included gatherings a tenable instrument to
execute their business concurrences with added cryptographic security.
The blockchain programs are new, complex, and profoundly
trial. Consistent changes are normal in the turn of events and security scene,
as new bugs and security hazards are found, and new prescribed procedures are
created.
