# Comparison

In this section, we cover the disadvantages of different protocols and file-sharing methods and examine their weaknesses.

# XDCC

XDCC (Xabi DCC or eXtended DCC) is a computer file sharing method which uses the Internet Relay Chat (IRC) network as a host service.

x XDCC Disadvantages
🔴 Requires a centralized indexer/tracker/lister which is subject to censorship and single point of failure
🔴 Transfer protocol rather than a complete file sharing solution
🔴 No built-in search functionality
🔴 No incentive to retain data

# Usenet

Usenet is a distributed discussion system since 1980.

x Usenet Disadvantages
🔴 Requires a centralized indexer/tracker/lister which is subject to censorship and single point of failure
🔴 Most of the time requires subscription and forces user to pay - what if only one single file is needed?
🔴 Although Usenet providers retain data, it still lacks the incentive mechanism which allows other peers to participate in the retention process
🔴 Usenet servers do not operate in a peer-to-peer model and most operators just have a cluster of servers which are owned by them

# BitTorrent

BitTorrent is a peer-to-peer file-sharing protocol that requires a client and trackers/DHT.

x BitTorrent Disadvantages
🔴 Requires a centralized indexer/tracker/lister which is subject to censorship and single point of failure
🔴 Inactive Torrents without seeders/Lack of incentive mechanism to reward peers for seeding
🔴 IP addresses are completely exposed. Anyone can see what user is downloading and uploading
🔴 (Optional) Requires additional VPN and proxy services which are paid services, to solve the above problem
🔴 Unstable download/upload speed

# Cyberlocker / Filehoster

A cyberlocker is a third-party online service that provides file-storing and file-sharing services.

x Cyberlocker / Filehoster Disadvantages
🔴 Requires a centralized indexer/tracker/lister which is subject to censorship and single point of failure
🔴 The Filehoster on its own is subject to censorship. (e.g megaupload was shut down by DOJ)
🔴 IRequires subscription and premium upgrades - what if only one single file is needed?
🔴 Extremely slow speeds which force users to pay for premium account
🔴 Inactive files are deleted after a few months / Lack of incentive mechanism
🔴 Your personal information and credit card data are in risk of being abused or sold since most operators disappear
