The Open-Source Framework for Real-Time Audio and Video at Scale

Real-time communication powers the modern digital world, from virtual healthcare and remote education to online gaming and live broadcasting. Today’s users expect seamless, low-latency, high-quality media experiences across devices. For developers building these applications, selecting the right communication infrastructure is critical. That’s where LiveKit comes in.

LiveKit is an
open-source platform that provides the building blocks for
real-time audio and video apps. With support for
WebRTC,
AI integrations, and
flexible deployment options (cloud or self-hosted), LiveKit helps developers build scalable, production-grade communication tools that meet the highest standards for performance and privacy.


What Is LiveKit?

LiveKit is a real-time communication framework designed to simplify the creation of interactive audio and video applications. Built on WebRTC, LiveKit provides:

  • A robust media server
  • Client SDKs for multiple platforms
  • End-to-end media encryption
  • AI integration support
  • Cloud and self-hosted deployment models

Unlike many closed, vendor-locked platforms, LiveKit’s
open-source model gives developers complete control over infrastructure and customisation, allowing for tailored experiences across industries.

How Does LiveKit Work?

At the core of LiveKit is an SFU (Selective Forwarding Unit), which efficiently routes video and audio streams without decoding or re-encoding them. This keeps latency low and CPU usage minimal, especially during group calls or interactive broadcasts.

  • A generous free tier

Perfect for startups, MVPs, and teams that want fast time-to-market without managing servers.

Scalability and Performance

LiveKit was designed for high performance under demanding workloads:

  • End-to-End Encryption (E2EE): Ensures complete privacy, even LiveKit itself can’t access media.
  • Global Scalability: Redis + Kubernetes allow for horizontal scaling across regions.
  • Bandwidth Optimisation: LiveKit dynamically adjusts media quality based on device and network conditions.
  • Adaptive Layers: For video resolution and bitrate to match various screen sizes and connectivity.
  • Stability Under Load: Real-time systems need to be reliable. LiveKit supports thousands of concurrent users with minimal latency and consistent quality.

AI-Powered Real-Time Applications

One of LiveKit’s unique strengths is its support for real-time AI use cases. Developers can route media streams directly into AI engines for processing and feedback.

Popular AI integrations include:

Ethereum Dust Attacks Have Increased Post-Fusaka

Ethereum Dust Attacks Have Increased Post-Fusaka

Stablecoin-fueled dusting attacks are now estimated to make up 11% of all Ethereum transactions and 26% of active addresses on an average day, after the Fusaka upgrade made transactions cheaper, according to Coin Metrics. 

Ethereum is now seeing more than 2 million average daily transactions, spiking to almost 2.9 million in mid-January, along with 1.4 million daily active addresses — a 60% increase over prior averages.

The Fusaka upgrade in December made using the network cheaper and easier by improving onchain data handling, reducing the cost of posting information from layer-2 networks back to Ethereum.

Digging through the dust on Ethereum

Coin Metrics said it analyzed over 227 million balance updates for USDC (USDC) and USDt (USDT) on Ethereum from November 2025 through January 2026.

It found that 43% were involved in transfers of less than $1 and 38% were under a single penny — “amounts with insignificant economic purpose other than wallet seeding.”

“The number of addresses holding small ‘dust’ balances, greater than zero but less than 1 native unit, has grown sharply, consistent with millions of wallets receiving tiny poisoning deposits.”

Pre-Fusaka, stablecoin dust accounted for roughly 3 to 5% of Ethereum transactions and 15 to 20% of active addresses, it said. 

“Post-Fusaka, these figures jumped to 10-15% of transactions and 25-35% of active addresses on a typical day, a 2-3x increase.”

However, the remaining 57% of balance updates involved transfers above $1, “suggesting the majority of stablecoin activity remains organic,” Coin Metrics stated.

Users need to be wary of address poisoning

In January, security researcher Andrey Sergeenkov pointed to a 170% increase in new wallet addresses in the week starting Jan. 12, and also suggested it was linked to a wave of address poisoning attacks taking advantage of low gas fees

These “dusting” attacks typically involve malicious actors sending fractions of a cent worth of a stablecoin from wallet addresses that resemble legitimate ones, duping users into copying the wrong address when making a transaction.

Sergeenkov said $740,000 had already been lost to address poisoning attacks. The top attacker sent nearly 3 million dust transfers for just $5,175 in stablecoin costs, according to Coin Metrics.

Dust does not represent genuine economic usage

Coin Metrics reported that approximately 250,000 to 350,000 daily Ethereum addresses are involved in stablecoin dust activity, but the majority of network growth has been genuine.  

“The majority of post-Fusaka growth reflects genuine usage, though dust activity is a factor worth noting when interpreting headline metrics.”
