@prateekreddy awesome work! I ran the bootstrap code 2.2-finished-code.js and then ran the code 2.3-finished-code.js which just dials to the bootstrap. It throws this error:

The error seems to disappear once we add secio in the next chapter. Is the support for plaintext removed in the latest version? can you check it out why?

Yes looks like encryption is mandatory now.

Other than the package version issue noted in my above comment, this looks great!

Per here, this can be fixed but you have to specify Plaintext as the connEncryption module in the options object for the node. I did this locally 2.2 and 2.3 completed code sections and it works fine.

const Plaintext = require('libp2p/src/insecure/plaintext')
...
let options = {
    modules: {
        transport: [ TCP, WS, WStar ],
        connEncryption: [Plaintext]
    },...

Nice work, can you check out why does the code 6.2-finished-code.js doesn't work? the code until chapter 5 works perfectly

Oops looks like I missed chapter 6 completely. Let me update the code in the chapter as well.

Fired up 2 nodes using the 6.2 finished code and it works great. Thanks for this!

@shresthagrawal @jjperezaguinaga Hey guys, any chance one of you can give this a final look so we can get it merged? I'd love to have it merged this weekend if possible so we can start merging the content updates in the other PRs.
