FREENET One of the oldest projects for distributed web (the initial realise was on 2000) This has, by default, anonymity This does not have support for dynamic content

ZERONET You need to use Tor in order to access ZeroNet This has support for dynamic content It has a plugin to use namecoin

Slide 21

Slide 21 text

SAFENETWORK It has a new cryptocoin, called Safecoin It uses Omni protocol

Slide 22

Slide 22 text

DAT It’s a "distributed file system" It keeps a secure version log of dataset changes You can download only a part of a big file (for example, some rows of a dataset) Decoupled for implementing lower-level object stores

Slide 23

Slide 23 text

IPFS InterPlanetary File System IPFS has no anonymity guarantees, neither in communication nor in the storage of data Its nature is to be a decoupled tool It has a cryptocoin (in developing), called Filecoin Created and maintained by Protocol Labs and community

HOW IPFS WORKS?

CONTENT-ADDRESSING

Slide 28

Slide 28 text

Currently, the "centralized web” uses the location-addressing For example, if I want get the Google’s logo…

The Google hash logo ( ) is hf9ndr98ydwrw We can use content-addressing instead of using the location-addressing Again the same example, but using content-addressing!

IPNS

Slide 43

Slide 43 text

Although the concept of content-addressing brings a bunch of benefits, sometimes it’d become unsuitable for cases where it’s necessary to constantly get the last version of something, since it’d need to get the hash of last version of the object in another channel. To solve this problem another protocol, called IPNS, was developed. With the peerID, the hash of the user's public key, it then became possible to create a redirect to a specific object.

LIVE CODING: USING IPNS

Slide 45

Slide 45 text

And you can configure your DNS to use your IPNS address ➜ ~ dig macalogs.io txt ;; ANSWER SECTION: macalogs.io. 600 IN TXT "dnslink=/ipns/QmUHQxrfru6Npch4VCaQqf22wEJ3BZx3UGmyfFRvyJFgHj"

Slide 46

Slide 46 text

But, it's slow to resolve the IPNS address. Curiously… The IPFS official site uses the the IPFS hash in DNS ➜ ~ dig ipfs.io txt ;; ANSWER SECTION: ipfs.io. 60 IN TXT "dnslink=/ipfs/QmQrX8hka2BtNHa8N8arAq16TCVx5qHcb46c5yPewRycLm"

PIN

Slide 48

Slide 48 text

Sometimes you want to be able to control what you keep around. Pinning is the mechanism that allows you to tell IPFS to keep a given object local or no.

Different of some systems like Freenet or ZeroNet, the user in IPFS can choose what he will storage In order to encourage the users to storage third party data, the Protocol Labs is developing a new currency
