# Trusted timestamps. Verified order.

Hedera Consensus Service acts like a decentralized notary, providing verifiable and immutable timestamps for events without storing the data itself. This ensures no single party controls the process, eliminating front-running and guaranteeing that everyone sees the same transaction order, exactly as it happened.

no node manipulation

## Fair and accurate transaction ordering

Transactions are timestamped based on when they’re seen by the majority of the network, not by any single node.

## Gossip about gossip

Nodes don’t just share transactions. They also share information about who they heard it from and when. This extra layer of information creates a trusted record of how data moves through the network.

## Virtual voting

Nodes don’t vote in real time. Instead, each one uses shared data to independently calculate the order of transactions. A consensus timestamp is then assigned based on when a supermajority of nodes first saw the transaction.

## Messages and consensus results

Messages can be public or encrypted with additional privacy. Every consensus result is verifiable and can be independently audited by anyone.

predict costs

## No gas = no guesswork

Hedera avoids gas-based pricing. Fees are predictable, set in USD, and converted to HBAR at the time of transaction. There are no surprises, just simple and reliable costs for every operation.

See the Fee Calculator for more details.
