Why Do Multiple Blockchains Exist?

**Blockchains **do not operate as a single global network, but as independent systems with different rules. That is why multiple blockchains exist in parallel rather than a single universal infrastructure.

Each blockchain is designed with specific priorities. Some optimize for security and decentralization, while others focus on higher processing speed or lower transaction costs. These differences are not accidental, but the result of design choices.

The core point is that it is not possible to optimize security, scalability, and decentralization at the same level simultaneously. This technical trade-off is what leads to the existence of multiple specialized networks.

In practice, this results in blockchains serving different roles within the ecosystem: some are used for high-value transactions and greater security, while others are designed for faster applications or lower operational costs.

Rather than competing to replace one another, blockchains coexist as distinct infrastructures that solve different problems within the same system.
