In order to make interaction with the contract easier, the address of the account can be assigned to a variable, there are a number of methods that are now exposed, and the contract can be further queried now, for example: > eth.getBalance(valuechecker.address) We can now call the actual methods in the contract.
There are various methods that have been exposed now, and a list can be seen as follows: > valuechecker.transactionHash “0x9f7c81a5942b01f2e2446cad6f0acbaa00514326fcf0abf7b7a076d172db05d6” > valuechecker.abi [{ constant: false, inputs: [{ name: “x”, type: “uint8” }], name: “Matcher”, outputs: [{ name: “”, type: “bool” }], payable: false, stateMutability: “nonpayable”, type: “function” }, { anonymous: false, inputs: [{ indexed: false, name: “returnValue”, type: “bool” }], name: “valueEvent”, type: “event” }] The contract can be further queried as shown here.
A Complete Guide to Understanding This Blockchain Concept
In the following example, the Matcher function is called with the arguments.
Arguments, also called parameters, are the values passed to the functions.
Remember that in the code, there is a condition that checks that if the value is equal to or greater than 10, then the function returns true; otherwise, it returns false.
Type the following commands in the geth console that is already open.
Pass 12 as an argument, which will return true as it is greater than 10.
Why This Matters for Blockchain Technology
Understanding Value checker attributes is not just an academic exercise — it has real-world implications for how blockchain systems are designed, deployed, and secured. Whether you are a developer building decentralized applications, a business leader evaluating blockchain adoption, or a curious learner exploring the technology, this knowledge provides a critical foundation.
Key Points to Remember
