# Distributed Ledger Technology (DLT)

Symemetry utilizes Distributed Ledger Technology (DLT) as a foundational element of its blockchain infrastructure, enabling secure, transparent, and efficient management of data. DLT decentralizes the storage, validation, and recording of all transactions, ensuring that all network activities are verifiable, tamper-proof, and accessible to participants without reliance on a centralized authority.

## Immutable Records

One of the core features of DLT is immutability—once a transaction is recorded on the blockchain, it cannot be altered or deleted. This guarantees that all records are permanent, creating a trustworthy and auditable trail of all network activities. Each transaction is linked to the previous one, forming an unchangeable chain that is transparent and verifiable by all participants.

This immutability ensures that once data is entered into the Symemetry blockchain, it cannot be manipulated, providing the highest level of security and trust. Users can rely on the fact that the data they interact with is accurate and permanent, making the system ideal for decentralized applications (dApps) and use cases like decentralized finance (DeFi), where data integrity is crucial.

## Decentralized Data Validation

In a DLT system, data is validated by a network of nodes rather than a central authority. This decentralized validation process involves multiple independent participants (nodes) validating each transaction before it is added to the ledger. Every node maintains a copy of the ledger, and new transactions must be agreed upon by the majority through a consensus mechanism. This ensures that all participants in the network have an identical and consistent view of the ledger.

By distributing the validation process across a decentralized network, Symemetry eliminates the risks associated with centralized data control, such as fraud, manipulation, and downtime. The consensus process used in Symemetry ensures that all data is accurately validated and securely recorded, with no single entity controlling or altering the data.
