# Transaction Check Per Second (TCPS)

Most blockchain networks offer probabilistic transaction certainty. In other words, transactions do not become definite immediately, they are finalized after a certain number of additional blocks are added to the chain. The main idea behind this solution is that as blocks are continuously confirmed and added, the probability that previous transactions will be valid and irreversible increases.

Although TPS measures speed, it may not correlate with certainty. A chain may have high TPS based on a reasonable definition of transactions but may take longer to establish precision depending on TCPS and TPS.

**Transaction Check Per Second (TCPS)** is the number of transactions that can be pre-verified and denied in an instant.

MetaChain with a brand new approach — thanks to the MetaMiner, MacroMiner, MicroMiner components and MetaAnthill technology, which form the consensus structure — optimally sustains the factors that other networks today have to waive with scaling solutions.

In the optimum hardware and network topology, the block time is less than 5 seconds and the node synchronization happens instantly.

In tests with 19 nodes, it was possible to verify and confirm more than 700,000 transactions per second. It is predicted that theoretically, as long as TCP (Transmission Control Protocol) support is provided, up to 3.3 million transactions per second could be reached.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.metaverse-ico.net/whitepaper/metachain/transaction-check-per-second-tcps.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
