# Welcome

:hand\_splayed:Hello Sentizens, <https://hub.sentre.io>

## Sentre in the first look

The first time of learning about Sen, you may be a bit confused amount Sentre, SenHub, and SenSwap. By the below explanation, we hope that we can make it clear to you:

* **Sentre** refers to the whole ecosystem, including everything such as SenSwap, SenHub, etc.
* **SenHub** is a platform that offers a base for blockchain developers to quickly build and ship decentralized applications (DApps) to users.

## Individual development is hard

If you are an individual developer and you're incubating an innovative idea, there are several things you need to do before success. [UniSwap](https://uniswap.org/) needed 2 years to bring their idea to people. [Compound](https://compound.finance/) had a talented team but also spent more than a year to launch the product.

After a long time of struggling with code on your local machine, you - an individual developer - need to rent servers, buy domains, subscribe to many third services just for an official launch. That may consume a lot of money.

:money\_with\_wings: You have to spend money on expensive services.

Furthermore, you have to do some marketing stuff that's even beyond the endurance of a geek. It's obvious that the process is very challenging and likely failed.

:exploding\_head: You have to do many things that aren't your strength.

In the end, the final evil is liquidity. If you build a DeFi protocol, liquidity is essential to run your protocol. Your idea may be never known by the public because of a lack of liquidity.

:droplet: Liquidity is a very limited resource for a new protocol.
