 # Chapter 15: Using i2p
 
-The Invisible Internet Project (I2P) is 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 your and your peers.
+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".
 
-Basic differences between Tor and i2p:
-
-|  | Tor | i2p |
-| :---         |     :---:      |          ---: |
-| Routing   | [Onion](https://www.onion-router.net/)     | [Garlic](https://geti2p.net/en/docs/how/garlic-routing)    |
-| Network Database     | Trusted [Directory Servers](https://blog.torproject.org/possible-upcoming-attempts-disable-tor-network)       | [Distributed network database](https://geti2p.net/en/docs/how/network-database)      |
-| Relay     | **Two-way** encrypted connections between each Relay       | **One-way** connections between every server in its tunnels      |
-| Hidden services     | Slow       | Fast      |

-Ports required by i2p:
-
-1. Outbound (Internet facing): a random port between 9000 and 31000 is selected however its better if all ports are open and it doesn't affect your security. You can check firewall status using `sudo ufw status verbose` which shouldn't deny outgoing by default.
-
-2. Inbound (Internet facing): Optional

-It is not installed by [Bitcoin Standup](https://github.com/BlockchainCommons/Bitcoin-Standup-Scripts) right now as i2p support was recently added in Bitcoin core. However, you can try it manually by following the steps mentioned in [Section One](15_1_i2p_service.md).
+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
+  * Run Bitcoin Core as an i2p (Invisible Internet Project) service
 
 Supporting objectives include the ability to:
 
   * Understand the i2p Network
-  * Learn difference between Tor and i2p
+  * Learn the difference between Tor and i2p
