1/ 🚀We’re thrilled to announce our $2.85M raise led by @lattice_fund!

The round also includes participation from incredible supporters including @allianceDAO, @protocollabs, @FinalityCap, @ZeePrimeCap, @RW3Venture and @toly, founder of @solana(🧵)

Elastic capacity without capex is underrated.
If you can scale by onboarding nodes instead of buying racks, burst events get a lot easier.

Think of a DePIN CDN like this:
Traditional CDN = few big warehouses
DePIN CDN = thousands of neighborhood depots
Same delivery model. Shorter trips.

blockcast. blockcats.

Last-mile performance isn’t a protocol problem.
It’s a placement problem.
Put the cache closer to users. Everything gets faster.

Multi-CDN with 3 similar providers = 3 copies of the same risk.
Real resilience comes from different footprints, not just different logos.

DePIN CDN ≠ P2P.
Still centralized control plane
Still encrypted
Still observable
Just more distributed cache locations.

Big difference.

Traditional CDN scaling = build data centers.

DePIN scaling = onboard operators.

Same software. Very different economics.

CDNs deliver 70%+ of the web… yet most capacity sits in the same metro IXs. “Global” doesn’t mean “everywhere.”

Rural + small ISP users still backhaul traffic upstream.

Topology > marketing.

If your cache isn’t inside the access network, you’re still paying the latency tax.

Every upstream hop adds TTFB.

Deeper cache placement beats bigger PoPs...and better delivery experiences.

CDNs haven't really changed over the last 15 years.

But it's about time that they did.

DePIN CDNs offer an improved, self-healing delivery architecture, a way to onboard new capacity (rather than building it), and support for non-traditional capacity like from ATSC 3 broadcasters.

Multicast is often thought of as one-to-many data transmission. Which is true, it stands apart from unicast which is always a one-to-one.

The true power of multicast is not in an individual sending data to multiple recipients. It is in a community of many senders sending data to many recipients simultaneously with orders of magnitude, lower bandwidth requirements and lower latency.

This is how multicast works in traditional finance, this is how multicast will work in crypto as well.

Another Cloudflare outage, maybe it's time to think about your multi-cdn strategy!

[Blockcast @BlockcastNet]

Why it matters: More users are being served by smaller ISPs that aren't peered with major CDNs. Blockcast's software-based approach lets any operator spin up a node and join our network—bringing better performance to users everywhere, not just big cities.

Does cache placement really matter for CDN performance?

We ran the experiment.

Short answer: Yes — it matters a lot.

[Blockcast @BlockcastNet]

We embedded a Blockcast RELAY node in a smaller network operator and saw dramatic improvements in latency and startup times compared to traditional CDNs.⚡ Lower latency🚀 Faster startup times 📈Consistently better QoE

@snov1n @mztacat nice job!

Multi-CDN strategies are essential—but they add complexity, especially when it comes to capacity reservations. Our latest blog explores why geography matters, how Open Caching helps, and how the Open Capacity Marketplace changes the game. 🌐✨

What makes #DePIN 🔧 truly game-changing is how different physical infrastructure providers - decentralized CDNs and ISPs 🤝 - can now work together—thanks to aligned crypto incentives 💸. This unlocks new infrastructure like Multicast 📡 that neither could build on their own. 🚀 Give it a read!

TLDR:

Blockcast × DAWN Partnership: Blockcast’s community-operated Content Delivery Network with its native multicast streaming protocol is integrated directly into DAWN’s Black Box, enabling massive global-scale livestreaming events over decentralized wireless networks.

Problem: Modern internet infrastructure relies on unicast streaming, inefficiently sending the same data streams to each downstream CDN node, causing catastrophic congestion during large huge livestream events.

Solution: multicast adaption technology—sending a single data stream simultaneously to unlimited viewers—through a CDN layer for unmodified applications, dramatically reducing bandwidth usage by up to 90%, and lower latency router replication vs server store and forward, providing seamless 4K and 8K streaming at unprecedented scale.
