To understand cryptocurrency, you must first understand the blockchain.
Imagine a notebook that everyone can see and no one can erase. Every page
of this notebook is a block of transactions. Once filled, its added to
the chain of previous pages, creating a permanent record.
Blockchain is the technology that enables the existence of cryptocurrency.
One of blockchain’s defining characteristics is transparency. All users
have the same access to information about all transactions made within the
network.

While blockchain is the most well-known and widely used technology for cryptocurrencies, it’s not the only one. The core concept that cryptocurrencies need is a distributed, secure, and transparent ledger. Blockchain achieves this through its chained blocks and cryptographic security. However, alternative technologies exist that aim to provide similar functionalities, sometimes with different trade-offs.
One such alternative is the Directed Acyclic Graph (DAG). DAGs structure data differently, allowing for potentially faster transaction speeds and greater scalability compared to traditional blockchains. Instead of blocks, transactions are linked directly to each other, creating a web-like structure. Examples of cryptocurrencies exploring DAG technology include IOTA and Nano.
Therefore, the answer to the question is no. While the vast majority of cryptocurrencies currently rely on blockchain technology, it is not a universal requirement. Innovation in the cryptocurrency space continues to explore different approaches to achieving decentralized, secure, and transparent ledgers, and DAGs are just one example of these alternatives. The future may see even more diverse technologies emerge, each with its own strengths and weaknesses, vying for adoption in the world of digital currencies.

The selection of a specific technology often hinges on the specific goals and priorities of the cryptocurrency project. Blockchains, with their proven security and widespread understanding, remain a solid choice for many applications. However, the limitations in scalability and transaction speed have spurred the development of alternatives like DAGs, which prioritize these aspects. Other technologies, such as Hashgraph, also present unique architectures with potential benefits.
Ultimately, the best technology depends on the specific use case. A cryptocurrency designed for high-volume microtransactions might benefit from the speed and scalability of a DAG, while a cryptocurrency focused on maximum security and immutability might prefer the robustness of a blockchain. The ongoing evolution of distributed ledger technology ensures a dynamic landscape with diverse solutions catering to various needs within the cryptocurrency ecosystem. The focus remains on creating secure, transparent, and efficient systems for managing and transferring digital value.
