@wedtm Did you say hi to our old friend stackoverflow?

[Triton One 🌊🌋 @triton_one]

Triton Preconfs is live, with our first partner BAM by @jito.

Each Solana transaction reaches you the moment the leader's scheduler accepts it, over gRPC, before the block is built, executed, or cut into shreds.

About 91% arrive ahead of a Geyser stream.

SGP-0002 passed.

We voted AGAINST, and we're being told we don't care about the chain. Here's the actual math: fixed costs, yield migration, and why faster disinflation concentrates stake. https://t.co/4IINz4GD8m

BREAKING: We're partnering with @SolanaFndn to rebuild Solana's read layer from the ground up.

@anza_xyz and @jump_firedancer have done incredible work scaling execution and networking, but the read layer has stayed largely unchanged since genesis. It was built alongside the validator and never got its own architecture.

By 2026, that gap shows: slower access, expensive customisation, and growing limitations at scale. The teams closest to the problem built great tools behind closed doors because the read path was too deeply coupled to the validator to improve without massive effort.

It's time Solana's data access layer matched the ecosystem's needs, and we're proud to be the ones building it:

Big news: reads are moving out of Agave into two modular systems, independently scalable, in sync with the network tip, open-source and managed by @SolanaFndn:

- Accounts: an adaptive indexing engine that ingests, stores, and serves the exact account data your app needs at extremely low latency

- Ledger: full architecture to ingest, store, and serve the entire ledger faster and more efficiently in a columnar engine purpose-designed for how builders query data

Every infrastructure provider, builder, dApp, and institution benefits, with the biggest impact coming from what gets built on top.

More technical posts coming as we build through 2026, so make sure to follow us on X and subscribe to our blog.

To save cost, we were considering switching away from @triton_one. Recently, our needs were significantly reduced.

But they introduce "pay-as-you-go": our bill went $500 -> $30/m.

Still have access to their whole infra and services.

We're staying!

There are a lot of changes coming to Solana this year.

A big one is related to Durable Nonces. Durable Nonces will be removed this year.

What does this mean for the devs?
1. A migration path must be decided
2. There will be a migration window after a proper path exists

@wedtm Why golang infra and which frameworks for frontend?

[Arthur Tavares @arthurpvares]

@redacted_noah Over the last 4 years i've been through every single step you mentioned . No setup I ever tried could address all those issues together but building an UX that understands the indexing times and confirmations while predicting state updates is what has worked best so far

I've joined @DoubleZero as Stake Pool Manager.

DoubleZero is tackling one of the hardest problems at the heart of the internet and of high-performance blockchains: global, base-layer connectivity.

Right now, validators struggle with unpredictable latency, high jitter, and shared bandwidth while competing with every other application on the web. DoubleZero is reimagining this from the ground up, creating a dedicated highway for blockchain traffic that enables validators to focus on what truly matters: optimizing block production.

With 2,200 Gbps of total throughput capacity and 34%+ of the Solana network already running on DoubleZero (increasing by the day), the foundation for Internet Capital Markets is being built here. This is the first step to bring NASDAQ on-chain.

As someone who runs a validator from Brazil (@PineStake), I've seen firsthand how hard decentralization can be when you're fighting against poor routing, network limitations, and connectivity gaps. DoubleZero makes it possible to achieve decentralization and keep performance at its peak.

If you're curious about connecting to DoubleZero or want to learn more about the DoubleZero Stake Pool, my DMs are always open.

Increase Bandwidth Reduce Latency.

Accelerate everything.

today, Solana changes forever

we've solved the biggest data/RPC problem that exists

solana historical/archival data — has now been redesigned

quick context:

today when you query historical data (getBlock/getTransaction/getSignaturesForAddress), it hits Google BigTable

this is i) slow, ii) expensive, iii) inflexible for queries

e.g., you physically can not get the first tx for a Solana address without looping back endlessly from the latest tx

for busy addresses, this can take thousands of RPC calls — extremely slow, expensive, and annoying

also, imagine you wanted to get the most recent 100 txs for an address, how do you do it?

you first hit getSignaturesForAddress to get all the tx signatures and then call getTransaction on each tx to get its details — this can take 1,001 RPC calls in the worst case

not anymore

we have built a new distributed archival storage system that is 1,000x faster, more flexible, and more scalable

the best part? we're introducing a new API method:

getTransactionsForAddress

with this method, you can now:

i) combine getSignaturesForAddress and getTransaction calls into just 1 call instead of 1,000

ii) you can search in reverse order without needing to traverse

iii) you can search historical transactions by time and slot ranges (e.g. get me all the txns from January 5th, 2025 until February 5th, 2025)

what's more:

- getBlock calls are now 10x faster
- getTransaction calls are now 10x faster
- getSignaturesForAddress calls are now 10x faster

10x lower latency, 100x fewer RPC calls, and 1000x less code

enjoy!

@cold_xyz Reminds me of when @_ilmoi reached out to me. Hopefully not too late to be a cofounder of @tensor_hq

[SkyTrade @SkyTradeNetwork]

Our CEO @droneevtol is at the @FT Digital Assets Summit (6-7th May, Convene 155 Bishopsgate, London, UK), joining the conversation on how Air Rights fit into the future of tokenisation, infrastructure and crypto.
Looking forward to connecting with builders, investors, and policymakers moving this space forward!

🇺🇸 Pine Stake just voted against SIMD 228. We believe that this change would affect negatively the chain and would lead to centralization of stake.

If you are looking for a validator advocating for you, stake with us!

🇧🇷 Pine Stake acaba de votar contra o SIMD 228. Acreditamos que essa mudança afetaria negativamente a rede e levaria à centralização de stake.

Se você está procurando um validador defendendo você, stake conosco!
