Tomorrow @ETHSofiaBG 🇧🇬 kicks off and our Chief Product Officer @sajidazouarhi will be onstage! Don't miss her panel "Building Under CROPS" at 4:25 PM! ethsofia.com/agenda

KBW is coming up soon! 🇰🇷 Catch @kentlinyy on the @ethereumkoreaio Staking Infra panel for an inside look at why top node operators are choosing mump2p.

Number go up 📈

September 29th @ KBW join us for CODED If you're interested in scalable blockchain infrastructure, stablecoins, payments, or AI agents we'd love to see you there! Co-hosted by Optimum, @googlecloud, @FourPillarsFP, LINE NEXT, and @Auros_global. Sign up: luma.com/bkffotv7

Optimum is hiring a trader. Not to trade. To tell us what's actually worth building. Ideal candidate is someone with a deep crypto trading / quant / market making background, who knows where latency matters most and what infrastructure limitations traders face today. You'll be working directly with our data, product, and BD teams to identify valuable opportunities, test hypotheses, lead collaboration with trading firms, and ultimately design products that translate speed into economic value for traders. Fully remote, high ownership role. Apply at: jobs.ashbyhq.com/optimum/9a3… or reach out directly.

New mump2p testing partner: @twinstake_io As an institutional staking provider, @twinstake_io is focused on delivering strong validator performance for its clients. Over the past 12 months, they’ve delivered a MEV APR around 35% above the Ethereum network average, and we’re excited to see how mum2p's ultra-fast data propagation can help push that performance even further. Welcome aboard 🤝

Quantum secure encryption already exists. Making it work fast enough for blockchains is the hard part... until you find out you can just use RLNC. coindesk.com/opinion/2026/09… Check out the new @MurielMedard article on @CoinDesk if you're interested in how PQ security can actually work. ☝️

150 milliseconds: How fast Optimum delivers data across the entire Ethereum network. 78 seconds: How fast @nevscape can explain why this tech is so valuable to the future of crypto.

Please welcome our new mump2p testing partner @dsrvlabs 👏 Staking over 300k ETH and known for their dedication to maximizing uptime, DSRV is a top node operator both in Korea and globally. We're very excited to have them on board, especially given their institutional staking expertise in the Korean market.

I think crypto as an industry is a bit torn between being a meritocracy that rewards measurable results, and an irrational hype driven market that puts narratives over evidence. That's just my perspective, I discussed this recently with @jilliangodsil of @blockleaders (you can find her piece at blockleaders.io/muriel-medar… ) but I'd love to hear what others think about this dynamic and how it may evolve as the industry matures.

Excellent post by @blocmates , capturing the essence of what @get_optimum does and why it does it.

A new data path to accelerate: Where latency will matter most when ePBS goes live on Ethereum There's a new data delivery race that's coming with Ethereum's Glamsterdam upgrade and it's headliner EIP-7732, known as ePBS. It shifts deadlines within a slot and changes the path that block data travels, creating new areas where low latency matters most. Today, there's a 4 second window at the beginning of each slot where block builders are sending bids through relays to the proposer. One of those bids get accepted, and then must reach the wider validator network for attestation. All this has to take place in under 4 seconds, so moving data quickly all across the world is essential. This is Optimum's bread and butter, getting blocks out to the network much faster than the standard libp2p gossip channel. Under ePBS the slot looks completely different. Notably, relays are out of the mix and bids get sent straight from builders to the proposer. The proposer chooses a winning bid, and they'll have that bid selected immediately at the start of the slot. Once the slot begins, the proposer sends out the new beacon block to the rest of the network for attestation. The deadline for attestation under ePBS is at the 3 second mark of the slot, 1 second earlier than today. However, the contents of that beacon block won't look the same as today either. Under ePBS the beacon block no longer contains the execution payload (the actual transactions being made), instead it contains a signed header identifying that payload. Proposer duties look relatively similar, except bid selection will occurring earlier, there's slightly less time to broadcast for attestations, and there's a lighter amount of data that needs to be sent in that phase. Fast data delivery is still important here, but the most economically important race now happens after attestation, between seconds 3-9 of the slot. This portion of the slot is where the winning builder must broadcast the execution payload to the whole validator network. Among the network, 512 validators are selected to serve as that slot's PTC (payload timeliness committee). If the whole PTC doesn't receive and vote on the payload by the 9 second mark the slot will go unfilled. In such case the builder, who already paid out the bid to the proposer, will be left holding the bag without getting the execution order they paid for. The Takeaway Under ePBS, builders are in a data delivery race that takes place over Ethereum's p2p gossip network. Optimum has already built an ultra fast p2p data delivery engine (mump2p). Naturally, we're preparing to offer our services to the builder market once Glamsterdam comes online, so they can consistently realize the economic value of having their bid selected.

Sometimes in the heat of battle you lose sight of what you're actually fighting for. In the battle for mass blockchain adoption, the core promise of decentralization is being sidelined in the name of scaling. But there's a better way. All it takes is a little bit of math...

What even is the point of blockchain if we have to give up decentralization to make it scale? We've somehow ended up treating better performance as a reason to compromise what makes blockchain different in the first place. So what if there's another way? 🌏 That's the rabbit hole we're going down in our latest Onchain World episode.
