# Chapter 15: Using I2P
There are alternatives to Tor. One is the Invisible Internet Project (I2P), a fully encrypted private network layer. It uses a distributed [network database](https://geti2p.net/en/docs/how/network-database) and encrypted unidirectional tunnels between peers. The biggest difference between Tor and I2P is that Tor is fundamentally a proxy network that offers internet services in a private form, while I2P is fundamentally a sequestered network that offers I2P services only to the I2P network, creating a "network within a network". However, you might just want it as an alternative, so that you're not dependent solely on Tor.
I2P is not currently installed by [Bitcoin Standup](https://github.com/BlockchainCommons/Bitcoin-Standup-Scripts), as I2P support was recently added in Bitcoin Core. However, this chapter explains how to manually install it.
## Objectives for This Chapter
After working through this chapter, a developer will be able to:
* Run Bitcoin Core as an I2P (Invisible Internet Project) service
Supporting objectives include the ability to:
* Understand the I2P Network
* Learn the difference between Tor and I2P
