Facebook to Roll Out Fizz Library

This library accelerates the deployment of TLS 1.3 over the Internet

Facebook introduced a library called Fizz, specially released for the recent update of TLS under the number 1.3. Fizz is a library that accelerates the deployment of TLS 1.3 over the Internet and increases the speed and security of applications and services.


  • Asynchronous I / O supported by default
  • Improved collection / spread of input / output required from copies of data.
  • Delays and loadings of service processors are reduced, which process trillions of requests per day.
  • Data is divided into "pieces" and encrypted.

Fizz and TLS 1.3 are globally applied in mobile Proxygen applications, in load balancers, in internal services and the QUIC library, mvfst. Currently, Facebook protects more than 50% of its traffic using Transport Layer Security. Applications that use Fizz perform fewer memory and copy allocations.

In TLS 1.3, the concept of "early data" (zero data, or data from 0-RTT) was introduced, which helped to reduce the waiting time. According to ITEF, it does this without waiting for the TLS acknowledgment. However, this concept can be unsafe, so Fizz includes an API that helps to get rid of shortcomings.

In addition, Fizz provides two types of APIs that can handle the rejection of "early data": transparently or allowing the application to modify the information sent repeatedly.

In 2019, the company plans to launch a large set of free online services for all game developers and distribute them as part of the GDPR agreement. They can be used in conjunction with any game engines, platforms and online stores.

Previously, these gaming services were designed specifically for Fortnite. During the existence of the game, Epic Games has tested them on 200 million players and 7 platforms.

First, the company will release the C SDK, which includes online services and integration with the Unreal Engine and Unity. It will only have a basic set of features available, but over time, Epic Games plans to expand it with the following cross-platform elements:

  • data storage and saving games in the cloud;
  • friends list, authorization, profile and rights management;
  • in-game voice communication system;
  • accounting of achievements and trophies;
  • group players and matches.

Also for the PC / Mac platforms, the Overlay API will be released, providing a user interface for logging into the game, a list of friends and other functions.

In the future, the company plans to add more features to the services - for example, creating custom content and anti-cheat system.
