Lantern is a free internet censorship circumvention tool that operates in some of the most extreme censorship environments, such as China, Iran, and Russia. It uses wide variety of protocols and techniques that obfuscate network traffic and/or co-mingle traffic with protocols censors are reluctant to block. It also uses domain fronting. It is not an anonymity tool like Tor.

Early versions of Lantern allowed users in countries having free internet access to share their internet connection with those who are in countries where the network is partly blocked. Network connections will be dispersed between multiple computers running Lantern so it will not put undue stress on a single connection or computer.

Lantern's CEO and lead developer is Adam Fisk, is a former lead engineer of LimeWire and LittleShoot.

In early December 2013, Lantern had a surge of Chinese users and could reach from 200 users to 10,000 users in just two weeks. Soon after that, the network was almost blocked by the Chinese government. Another surge occurred after the 2022 Russian invasion of Ukraine when internet freedoms in Russia were severely curtailed.

The software received US$2.2 million (HK$17.1 million) in seed funding from the US State Department.

Lantern is hosted on a wide variety and continually changing set of data centers around the world. It has used Digital Ocean at times, which was briefly reported as blocked in Iran during the civil unrest on January 2, 2018.

History

In early versions, Lantern's framework required the use of Google Talk for users to invite other trusted users from their Google Talk contacts. It has received funding from the US Department of State. This has raised some concerns about the privacy of users, though Fisk has said the State Department is "incredibly hands off" and never dictates how they should write Lantern, or how they should talk about it.

Users are not required to connect by invite since version 2.0 was released in 2015.

At the beginning of 2019, it was reported that the Guangdong police had imposed penalties on the basis of the "Interim Provisions on the Administration of the International Network of Computer Information Network of the People's Republic of China" for a Lantern user to "create and use illegal channels for international networking." The fine is a thousand Yuan. The document of the punishment was publicized on the “Guangdong Public Security Law Enforcement Information Disclosure Platform”.
In March of 2022 it was reported that Russian users were employing Lantern to bypass censorship measures put in place by the Russian government.
