Excited to share that I've joined @Sei_Labs as a protocol engineer on the consensus team.
I'll be working on Sei Giga to help build the infrastructure for high-performance on-chain markets.

Last year when they announced @EFDevcon would be in Mumbai, I already knew people were going to complain.
Anyone landing in Mumbai and seeing the traffic, the crowds, the missing footpaths, the AQI is going to react. I’m Indian and I know Mumbai is not comparable to many top-tier cities. I’m not going to pretend otherwise.
Still, the broad takes bother me. India has the largest population in the world and the infrastructure never caught up. Cities like Mumbai keep pulling in people looking for work and better lives, so the same limited roads and systems get more pressure every year. That is most of what people are seeing.
A few days in Mumbai also doesn’t show the rest of the country. The smaller towns, the hills, the villages, the different ways people live and work. That part gets left out of the generalisation.
What a short trip also misses is the underlying drive. Across almost every field, Indians show up disproportionately, both inside the country and outside it. The average person here is constantly trying to move up a level - better work, better education, better life for their kids. It doesn’t pause, and it rarely feels satisfied. That hunger and drive sits underneath a lot of the chaos. People are still pushing hard with whatever infrastructure and opportunity they have.
I’m glad Devcon happened here. It gave Indian builders direct access to people they usually only interact with online. But if the only thing that sticks with you is the disorder of the city, you’re missing the more interesting part: a society that keeps trying to outrun its constraints.

here's how we have designed our archival state to scale to Giga throughput. lsm trees handle the massive load we need, but pruning was a challenge.
we fixed it using undo logs and buckets with bloom filters, making pruning close to O(1), going from hours to ms.
a very different approach with respect to other clients, that index changes by block height. maintaining these indexes requires reads in the write path, that were also a limiting factor.
no reads in the write path = higher throughput
blocks organised in buckets = O(1) prunning
Scaling Sei's storage to handle 200K TPS is extremely challenging.
Every 24 hours Giga could create as much state as Ethereum has in its entire history.
To keep up, Sei is splitting Giga's storage in two. @alrevuelta explains how.

hi, i'm shivank. currently unemployed.
3.5 years across defi, fintech and AI. scaled an agentic AI trading platform to 9,000 users and $450K TVL. led engineering for b2b + b2c payments infra doing $100K/month.
looking for the next thing: a hard problem, real ownership, any space.
checkout the video below.
If you’re hiring, reach out to him. He’s been a great mentor and someone I’ve really enjoyed working with.
hey folks 👋 I’m open to new challenges - backend/protocol eng, tech lead or EM. into web3, AI, or web2, whatever’s genuinely interesting.
11 yrs building things, 6 deep in web3 - distributed systems, consensus, cross-chain infra, some open source, and lately exploring AI/agent infrastructure too.
go/rust/python person. DMs open 🙌

Introducing WhoDis🎭, a Chrome extension that lets you impersonate any Ethereum address.
No private keys.
It's open source.
Just paste an address → browse dApps as them (read-only).
Dev testing 🤝 degen lurking.

The default blockchain for onchain experiences.
Whether you’ve paid, sent, predicted, earned, borrowed, collected, or staked onchain - it probably happened on Polygon.
When Polymarket wins big, it’s “Ethereum,” but Polygon itself is not Ethereum.
Hits hard

Yet another massive upgrade went live on Polygon.
Godspeed ⚡️
A global network for onchain payments needs to be fast, light, and reliable.
Polygon’s Rio upgrade delivers.
Introducing a new-look, rehauled with: near-instant finality, zero risk of reorgs, lightweight nodes, and the path to ~5k TPS.
Rio is everything you need in global payments rails, ready to go and live on mainnet.

The most complex upgrade in Polygon history is live! Heimdall v2 brings:
• finality down to ~5 seconds (from ~1min)
• better network stability
• modern, future-proof core infrastructure
The team worked diligently with node operators to ensure a smooth upgrade, and despite a longer window of maintenance than expected, the new upgrade is whirring.
Good for users, good for developers, good for payments. We’re so excited to show you what we can do.

Polygon PoS Heimdall v2 Migration
Mainnet migration is now in progress with the deployment window expected for the next 3 hours.
Technical context: forum.polygon.technology/t/h…
During this window, users will be unable to use Polygon Portal for canonical bridging or the Polygon staking app to stake.

wake the fk up samurai. this is katana.
not just another general purpose chain. a defi chain forged to kill idle assets via deep liquidity & high yield. public mainnet coming late june.
incubated by @0xpolygon x @gsr_io
pre-deposits live ⚔️ stop sleeping on your bags

Go beyond the docs. Agglayer just got visual.
Introducing the Agglayer Visualizer: a 3D interactive tool for exploring how unified bridging and crosschain settlement actually work under the hood.
If you’re a visual learner, you’ll want to check this out ⬇️
Woop woop! New release of @0xPolygon PoS's execution client (bor) now supports "snap" syncing mechanism which syncs mainnet in ~30 hours (~6 TB state) from scratch compared to weeks in full sync.
Node operators give it a try: github.com/maticnetwork/bor/…
Some back story...
Experimenting with snap sync was my first task when I joined the team back in 2021. We couldn't get the healing phase of sync to complete because of the enormous state size and 2s blocks.
Eventually, we did manage to make it work but with changes which had other side effects..

📣 CDK goes multistack 📣
Aggregating web3 means meeting builders where they are – with more freedom and fewer limitations.
We're thrilled to announce the newest addition to Agglayer: the CDK OP Stack configuration, with native Agglayer interop. A new way to build OP Stack chains, supercharged with zk tech and maximum sovereignty. Without the silos, 15% tax, or seven-day delays.
With OP stack joining the current CDK Erigon stack, this is the first of many stacks to aggregate everything on Agglayer.

DiceDB 1.0 is here 🎉
What if, overnight, your cache became faster, fully multi-threaded, and reactive - pushing real-time updates to clients effortlessly without extra complexity?
Modern applications demand speed, scalability, and real-time updates. But most existing databases and caches weren’t built for true reactivity, forcing devs to write extra code for polling and managing states.
That’s exactly what we set out to solve. No more unnecessary polling—just instant, efficient updates when data changes.
Watch the announcement video (linked in the subsequent tweet), where I showcase reactivity in action, a powerful use case, and how DiceDB helps you build low-latency applications.
We are re-imagining what a modern cache should do.
We are re-imagining how data is delivered to the clients.
We are re-imaging the real-time data stack.
DiceDB isn’t just another cache - it’s a fundamental shift in how modern applications handle real-time data.
Give it a spin.
Super thankful to all contributors and maintainers of DiceDB :) It would not have been possible without them.
