Speed is money.
Every millisecond counts.
On Ethereum, the validator who sees a block first attests on time, picks from better MEV bids, and gets its proposal out before the cutoff. Optimum gets your data there first.
The universal data
acceleration network
Optimum fixes data movement at the foundation, working directly with validators to enable faster, more bandwidth efficient propagation across any blockchain. Most networking burns time and bandwidth on redundant transmission. Optimizing data movement allows networks to transmit less and deliver more.
No consensus changes
Chains keep their existing rules. Optimum improves propagation complementing the current stack.
Chain-agnostic by design
Integrates with any blockchain without requiring protocol rewrites.
Complementary to scaling
Works alongside execution, enabling network scaling while improving performance.

RLNC technology optimizes data transmission. Your nodes send and receive far less data, dramatically cutting bandwidth costs.
Permissionless, Zero-Setup Integration
No infrastructure changes. No additional hardware. No consensus modifications.
Maximize Validator Earnings
More successful attestations, better MEV capture, and fewer missed proposals mean measurable revenue gains.

testimonials
Luganodes has always focused on delivering institutional-grade infrastructure, with Ethereum as a core network. With mump2p bringing fundamental improvements to the p2p layer using RLNC, we’re excited to test and support this upgrade. Optimum enables us to further optimize our infrastructure and continue delivering reliable, high-performance staking services to our clients.
mump2p gives us a measurable edge with lower latency, fewer missed blocks, and more predictable rewards. It’s a meaningful upgrade to our infrastructure stack. Our institutional and retail staking clients expect high performance and reliability. By integrating mump2p, we’re helping ensure they receive the most consistent and rewarding staking experience possible.
We view scalability as one of Ethereum’s most critical challenges — and the gateway to mass adoption. Optimum’s innovative approach to memory layer optimization through RLNC is a game-changer. By accelerating data propagation and improving real-time access, Optimum directly supports the scalability and robustness of the Ethereum ecosystem.
mump2p’s RLNC-based propagation layer reduces redundant traffic and accelerates block and attestation transmission. This leads to faster inclusion, lower bandwidth costs, and improved MEV capture potential. It is a meaningful upgrade for validator operations and staking performance.
Improving data propagation is just as important as execution or consensus when it comes to scaling Ethereum. mump2p addresses this often-overlooked bottleneck, making propagation faster and more consistent across the network. We look forward to continuing our implementation and exploring how it can further optimize validator performance at scale.

FAQs
What is Optimum, who is it for?
Optimum is a data acceleration network that improves how data moves across decentralized blockchains. It reduces redundant transmission so blocks and critical payloads propagate faster and more consistently under real network conditions - without touching consensus or requiring protocol changes. It is built for validators and node operators who want better economics, and for chains that want to raise their performance ceiling without a hardware arms race.
Is Optimum a blockchain?
No. Optimum is a network that operates alongside blockchains, not a chain itself. It does not have its own consensus, does not process transactions, and integration does not require any chain to change its execution or consensus rules. Validators keep their full existing stack and add Optimum to improve how quickly and consistently they see and send data.
How does Optimum improve validator performance?
Propagation latency directly affects validator outcomes. Faster, more consistent block delivery reduces missed attestations, lowers the risk of missing a block proposal, and improves reward predictability. On Ethereum mainnet, Optimum delivers blocks 2-4x faster than the Gossipsub baseline, and roughly 90% of the time the Optimum network sees a block before the rest of the network. Validators get this through two services: Signal, which lets you receive blocks and attestations first, and Accelerate, which propagates the blocks and attestations you send faster. Live network performance is published on the Optimum Hub.
As an Ethereum Validator, what infrastructure changes do I need to make?
Minimal. mump2p runs as a sidecar alongside your existing Ethereum client and integrates via a simple API call. It does not replace your consensus client, modify your signing setup, or require new hardware. Overhead is low enough that any validator can run it regardless of hardware spec. Sign up through the Optimum console to get started.
How do I integrate mump2p and which CL clients are supported?
Sign up through the Optimum console, then follow the integration steps in our docs. The Optimum sidecar runs on your machine, reads block and attestation data from your Ethereum client, and passes it to the Optimum network, which encodes it using RLNC and sends encoded packets to the network. Signal is open to any Ethereum validator. Accelerate is available to operators running 200 or more validators. For the current list of supported consensus clients, check our docs.
Is Optimum live on Ethereum mainnet?
Yes. Optimum launched on Ethereum mainnet in October 2026 with an initial group of leading validators and node operators boosting their stake, following an extended run on Ethereum's Hoodi testnet. The current list of mainnet partners, stake on the network, and live performance figures are published on the Optimum Hub. Any Ethereum validator can sign up through the Optimum console.
What happens if Optimum or mump2p service is interrupted?
Validators run Gossipsub in parallel with mump2p at all times and continue using it to communicate with nodes not running Optimum. mump2p is additive - your consensus setup has no dependency on it. If the sidecar goes down, your ability to attest and propose blocks is unaffected. For specific failure handling behavior, refer to the operator docs.
What are Signal and Accelerate?
Signal and Accelerate are the two services available on the Optimum network. Signal lets your validator receive blocks and attestations earlier than it would over Gossipsub alone. Accelerate propagates the blocks and attestations your validator sends to the rest of the network faster. Both run through the same mump2p sidecar.
Does Optimum affect consensus, leader selection, or validator keys?
No. Optimum operates purely at the propagation layer. It has no access to validator keys, plays no role in leader selection or signing, and does not modify consensus behavior in any way. It changes how data moves and nothing else.
What does it cost to use Optimum services?
Signal is free for Ethereum validators. Sign up through the Optimum console.
