@helius, it’s just state commitments

[Jorrit @ananas_light]

Very excited to join Helius as Head of Privacy.

Since 2021 we solved the core building blocks of onchain privacy: single-tx ZK verification, and cheap scalable nullifier storage.

At Helius we will fuse them into the most scalable programmable privacy protocol directly on Solana

[Helius @Helius]

Big Solana news:

The Light Protocol team is joining Helius to help build Solana's most complete ZK privacy layer.

Private payments, markets, and finance -- at Solana scale.

Fully composable, fully onchain, fully open-source.

Excited to join @HeliusPrivacy to grow the Solana Privacy Protocol.

After years of building ZK and scaling infrastructure on Solana, we're ready to close the gap standing between crypto and mainstream adoption.

We'll make privacy accessible on Solana through simple APIs for internet finance and capital markets.

[Stepan | squads.xyz @SimkinStepan]

Two of my favorite teams partnering up.

Excited to be a launch partner with @altitude, making onchain money movement private for businesses, at Solana speed.

@0xNIC0 Thank you Nico!
Encrypt everything.

Colosseum Frontier Workshops by @SuperteamBlack - How to Build with ZK Compression on Solana with @tilo_cpn from @LightProtocol https://t.co/doRljp2I7I

[Jorrit @ananas_light]

Solana account costs are too high and rent reductions are not enough for payments at scale.
That’s why we built light-token.
Costs near compressed tokens.
UX and Devx of Solana accounts.

[Light Protocol @LightProtocol]

Introducing the Light Token SDK for Payments

- reduces Solana ATA fees to $0.001

- works with all SPL, including USDC, PYUSD, USDG

- new drop-in API, upgrading from spl-token takes ~5 minutes

Live on Mainnet today, use with all leading RPC providers.

Enjoy

[VeryAI @VeryAI]

Human verification needs to scale to billions of users. That’s why we’re partnering with @LightProtocol.

Using ZK Compression, VeryAI records verification events on @solana with compressed accounts that are ~5,000× cheaper than standard accounts.

The result: verifiable onchain proofs without exposing user data.

Proof of Reality for the new internet.

Light Protocol ZK workshop: Solana Privacy Hack https://t.co/Ya5E918LlP

[Light Protocol @LightProtocol]

Today, we're introducing the Light token program, a high-performance token standard for rent-free DeFi on @solana.

It reduces the cost of allocating onchain accounts by 200x while being more CU efficient than SPL-token on hot paths.

@jacobvcreech @redacted_noah light-zero-copy implements borsh compatible zero copy macros that can handle strings options vecs and unaligned memory.
Probably not mature enough for default anchor integration but a start.

[Jorrit @ananas_light]

@redacted_noah Yeah pretty much, similar to a struct of references with the same fields as borsh struct.
The first fields that implement Copy are aggregated into a single zero copy until one field doesn’t.
After that it does multiple zerocopies for non copy types eg options and vecs.

[Jorrit @ananas_light]

@redacted_noah its a derive macro based on the zerocopy crate.
It derives an optimised Zstruct for your borsh struct and does multiple casts to support options and vectors.
Its on crates io

but no docs see tests as example

zk ID example repo
https://t.co/tQlkfHJ77T

[Jorrit @ananas_light]

Built a zk ID example with compressed accounts.

- private onchain id verification with Groth16 zk proofs
- compressed pdas to nullify id verification for an event
- no custom indexer required, Rpcs already index compressed accounts in state trees

[tilo | helius.dev/privacy @tilo_cpn]

Attention Cypherpunk builders from Portugal!

Another week, another ZK Compression workshop.

This wednesday, 11 AM (WEST) at the @SolanaPT buildstation & online

you'll learn
> how to use rent-free accounts
> how ZK Compression works
> demo & q&a

@BasedOrion_ Wincode v0.1.2 with pod annotations is 2x + less CU than borsh depends on the struct

[Jorrit @ananas_light]

@shankstwin @solana You can remove the pda rent costs entirely if you put the metadata into a compressed account.

[Jorrit @ananas_light]

@sonic_from_ny You are right, with pod annotations wincode is 588 CU.

[Jorrit @ananas_light]

Benched wincode for instruction data
(156 bytes, incl 3 options, 1 Vec<u8>)

Wincode: 1,402 CU
Bincode: 3,224 CU
Borsh: 421 CU
rkyv: 172 CU
borsh zero copy: 124 CU

Interesting that bincode serialisation adds that much overhead.
see below for the benchmark code.

[Jorrit @ananas_light]

Wincode with pod annotations: 619 CU
