IOTA to Prevent Sybil Attacks on Its Chain Using Mana-Based System

The name of Sybil attacks originates from the name of Sybil Dorsett, a US artist, who suffered from dissociative identity disorder and was known to have 16 different identities.

A sort of a hackers’ attack when cyber criminals emulate multiple identities, therefore, is called a Sybil attack. Now the IOTA Foundation has found a way of preventing them.

A new way of preventing Sybil attacks

The term was introduces by John Douceur, a researcher from Microsoft as he suggested that the emulation of multiple identities can also happen in blockchain systems.

On the IOTA chain, a distributed computing environment consists of nodes. Identities on IOTA are assigned to those nodes to give them votes or allow access to the network. Thus, nodes on IOTA become vulnerable to Sybil attacks.

Previously, IT engineers stood up to those using resource testing, which implied using either the proof-of-work consensus mechanism or the proof-of-stake one. Now, the Coordicide team has introduced a new tool – mana.
