the seed vault UX on @solanamobile is really underrated

a phone that you can use as a hardware wallet with biometrics is 10x UX and peace of mind unlock

imagine how much more usable and secure crypto would be if all iphones came with an integrated private key

I think as crypto grows, in the future all phones will have this feature

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!

hold up wait, i totally missed this

but if you look at basescan

there was a period of rougly 500+ blocks with 0 user transactions (i.e., an outage)

am I reading this wrong or why was there absolutely 0 coverage for the biggest L2 in crypto being down? Image
example block: basescan.org/block/20071525
you gotta be kidding me man

there was ZERO media coverage. still no coverage at all actually, except for the base status page mentioning an incident of "delayed transactions" Image

some upcoming things:

- 2 killer consumer features
- Frankendancer (Solana client w Firedancer networking stack)
- ZK compression (Solana 1,000x cheaper with zk)
- Firedancer (no comment needed)
- Mythril (full node client w lower hardware reqs)
- Sov rollups on Solana
oh and ore v2
oh and also runtimev2, hopefully doubling block cap, async program exec, multiple leaders, etc etc

this is arguably the best application of crypto I've seen yet — everyone needs to talk about it more

traditional mapping is a monopoly, expensive, and inefficient

how it works is that Google has cars that drive around and gather data periodically and charge super high fees since this data is very hard to get

with crypto, you can give people all around the world the ability to earn by adding dashcams to their cars and map the world in real-time

the result is that you get:

i) much fresher mapping data (Google Maps might take months to re-map something!!)

ii) much better economics

iii) much better composability and network effects

the end result is a much better real-time world map than any centralized institution can provide

the team behind it is @Hivemapper and they're building on SolanaImage
this is so sick — crypto enabling better real world systems Image
and of course

we had on @aseidman, one of the most based founders I've ever seen, on Lightspeed

the situation is escalating fast Image
i am confident this will change her mind on crypto
bro stop buying these whenever I tweet lol, I am **not** trading these

I don't hold anything but almost all SOL and some BONK, JTO, WEN lol

hot take

OG ETH crowd (who genuinely care about the future of crypto, not just their own bags or twitter engagement) will actually come around to appreciate SOL

now that tourists & predators have been washed out — only the real ones who want a better future will be left
ETH & SOL approach scaling much differently —but I don't see why that has to be a fighting point

the *real* problem is that crypto apps barely have PMF

it doesn't matter who can scale to handle the next billion users...if there's not a billion users who even want to use this
that is to say — EVM & SOL, while having some overlap — do ultimately enable different design spaces

we need to explore these design spaces relentlessly to maximize the number of possible applications with mass PMF
