Interoperability: How Different Blockchains Communicate

Interoperability: How Different Blockchains Communicate Blockchain technology has transformed the way we think about money, data, and trust. However, as thousands of blockchains have emerged—Bitcoin, Ethereum, Solana, Polkadot, and many more—a major challenge has become obvious: these blockchains don’t naturally talk to each other. This is where interoperability comes in. What Is Blockchain Interoperability? Blockchain interoperability refers to the ability of different blockchain networks to exchange data, assets, and information seamlessly. Just like the internet connects different websites and servers, interoperability aims to connect isolated blockchains into a unified ecosystem. Without interoperability, each blockchain operates like a separate island—powerful but limited. Why Interoperability Is Important Interoperability is critical for the future of blockchain adoption because it: * Enables asset transfers between blockchains (e.g., moving tokens from Ethereum to Solana) * Impr...

Basic data types

BASIC DATA TYPES
Data type defines the group of values that a data item can take and the operations that can be performed on the item. C language provides four basic data types. Below table lists the data types, their size, range, and usage for a C programmer.
The char data type is of one byte and is used to store single characters. Note that C does not give any data type for storing text. This is because text is made up of individual characters.You might have been surprised to see that the range of char is given as –128 to 127. char is used to store characters not numbers, so why this range? The answer is that in the memory, characters are stored in the form of ASCII codes. For example, the character ‘A’ has the ASCII code of value 65. In memory we will not store ‘A’ but stored as 65 (in binary number format). 

Table: Basic data types in c
In addition, C also supports four modifiers two sign specifiers (signed andunsigned) and two size specifiers (short and long). Table below shows the variants of basic data types.
Table: Basic data types and their variants
While the smaller data types take less memory, the larger data types incur a performance penalty. Although the data type we use for our variables does not have a big impact on the speed or memory usage of the application, we should always try to use int unless there is a need to use 
any other data type.

Embracing the Future: Resource Recovery from Waste

As global populations swell and industrial activities intensify, the amount of waste we generate is skyrocketing. Landfills, once considered an adequate solution, are now recognized as unsustainable and environmentally damaging. Enter resource recovery from waste – a transformative approach that views waste not as a problem, but as a potential treasure trove of resources. This blog post delves into the concept, methods, and benefits of resource recovery, illuminating how this practice is reshaping waste management and sustainability. What is Resource Recovery? Resource recovery refers to the process of extracting useful materials or energy from waste. Instead of simply discarding waste, resource recovery emphasizes reusing, recycling, and repurposing materials to reduce the volume of waste sent to landfills and minimize environmental impact. Key Methods of Resource Recovery Recycling: This is perhaps the most well-known form of resource recovery. Recycling involves converting waste mat...
