Requirements for profitable block building

Largest basket of transactions

Blocknative runs multiple nodes in multiple geographies giving you a comprehensive, low latency, census-level view of pending transactions. With the best view of the mempool you can include the most profitable transactions in your block.

Real time filtering for less noise

Easily and comprehensively filter decoded transactions using Blocknative’s low-latency, real time, census level Mempool platform. Automatically filter out unnecessary transactions from the start through our customizable filters and subscriptions.

Optimized arbitrage opportunities

Simulate bundles to preview net-balance change and smart contract calls. Automatically filter out unnecessary transactions from the start through our customizable filters and subscriptions.

Quick, reliable sending & receiving of blocks

Blocknative’s private, trusted relay connected to our global Transaction Distribution Network (TDN) has built in redundancy and data storage so your block is always delivered, no matter what.

Maximum gas profitability

Blocknative’s Gas Platform considers the size of transactions and gas prices to give you the most accurate understanding of what transactions to include in your block ensuring your block has the best chance of winning.

Block Building FAQ

Block Building is a newly accessible category that emerges when Ethereum shifts from PoW to PoS. The innovation which allows for this new block building capability is separation of block production from proposers, otherwise known as PBS (proposer-builder separation). At the merge we will see an off chain intermediate version of PBS enabled by MEV-boost which will be used until the fully in protocol PBS goes live (probably in a year or two).

Lorem Ipsum....

How Block Building Affects the Entire Ethereum Ecosystem / How do you know if block building is right for you?

Block builders decide what happens in a transaction's lifecycle by taking the contents of the mempool, private orders, and MEV bundles, to move a transaction from the pre-chain layer to on-chain. No matter where you interact with the blockchain, block builders affect you and it is important to understand how.

Transaction Originator

As the transaction source, you power the possibilities in the mempool. MEV searchers look at your transactions to find arbitrage opportunities. Sometimes this has no effect on you and sometimes this has a negative impact. We are building the infrastructure that lets you decide what you want to participate in.

Protect Your Downside

The Blocknative Relay is the only open source relay not based on Flashbots relay code.
Only Two Code Repositories

1. Flashbots

2. Blocknative's Dreamboat

97.3% Dependance

97.3% of the network using relays is entirely dependent on Flashbot’s relay implementation.

 

High Susceptibility to Bugs
Being dependent on a single source code makes you susceptible to bugs that could leave you with empty blocks.

Maximize your upside

Half of blocks created since The Merge contain no MEV. If you’re only thinking about MEV blocks you are losing out on profit by not optimizing your validator to maximize profit for half the network. The average validator node gets one block every 62 days. Ensure you maximize your upside by optimizing for these blocks.

Why connecting to multiple relays is important.

Network Security

Become a block builder to strengthen the robustness and decentralization of Ethereum by increasing the diversity of block builders.

Dynamic Inclusion

Decide what transactions are added to the blockchain based on your values. Align behind trusted, reliable, transparent relays that align to your point of view.

Active Participation

Be an integral part of the PoS Ethereum ecosystem by enabling Proposer/Builder Separation. Reliably send blocks and payloads to keep the ecosystem running and decentralized.

Blocknative MEV Relay

Blocknative is proud to contribute to the decentralization of Ethereum block building infrastructure. Share our vision of network neutrality by connecting your validator to our public, peer-reviewed, open-source relay: Blocknative Relay.

The relay is easy to use, only requiring one component to stand up and no external services.

Blocknative Relay FAQs

Blocknative is committed to upholding our relay to commonly adopted community standards.

Yes. We support all Relay API specifications and continue to monitor and make changes as the specs evolve. See our docs here.

We currently use feeRecipient to minimize complexity and cost (by avoiding additional transfer transactions). We do so in a setting where we don't accept externally built blocks. We are moving towards using last transaction payment when our builder starts accepting bundles.

Blocknative has 4 years of experience operating low-latency, highly reliable infrastructure for Ethereum. The Ethereum Foundation, Curve, and Metamask are among the entities that use Blocknative's infrastructure. Blocknative's gas extension is used by 40K+ users and github dependencies on our open source libraries crossed the 8k mark.

Yes. The Blocknative Relay is built upon our open source code Dreamboat. We believe relay diversity to be critical to network resiliency so our team built Dreamboat independent from Flashbots' Relay code to strengthen the health of the network. As of Nov 1, 2022, the Blocknative Relay is the only relay using a non-flashbots based relay implementation.

The Blocknative Relay has a transparent deployment process. For every new release of relay we build the artifacts for that release using Github Actions. Anyone can see these here as our repo is open source.

Yes. Our relay endpoints are documented here. We also have a dashboard page for our relay with useful resources and data for the community.

Yes. The Blocknative Relay filters transactions to/from any addresses on the OFAC SDN list.

Currently, the Blocknative Relay only accepts blocks from the trusted Blocknative Block Builder. We are planning to add external builder support soon.

Yes, if a high severity bug is found the Blocknative Relay would be taken down and the ecosystem would be notified via our Discord. We encourage anyone using MEV-boost to run more than one relay to always have a fallback.

Yes, it is Blocknative's policy to systematically publish an incident report on Discord in case of a major issue. We also regularly post status updates there for the community for non-critical incidents. The Blocknative Relay has not encountered any major bugs since it launched. You can find an example of an incident report in Blocknative's Discord here.

Yes. This is the endpoint https://0x8f7b17a74569b7a57e9bdafd2e159380759f5dc3ccbd4bf600414147e8c4e1dc6ebada83c0139ac15850eb6c975e82d0@builder-relay-goerli.blocknative.com

Yes. We do support relay monitoring based on the guidelines set forth by Flashbots and we do not impose rate limiting on monitors.

Connect with us on block building.

We love to talk to individuals and teams that are thinking about block building.

"Decentralization is critical at every level of the Ethereum network – including block building. Our team is opening up access to Blocknative’s real-time Web3 infrastructure in an effort to enable virtually any network participant to become a block builder. Ultimately, our goal is to drive block builder diversity and equitable value recirculation throughout the Web3 transaction supply chain."
