Fighting in the trenches of shit coinery

[Roger Wattenhofer @TheWattenhofer]

Quantum computers don't exist, but they're already reshaping cryptography.

Cryptography is becoming hashing.

We show that the functionality of BLS aggregate signatures can be achieved with only hashing: https://t.co/UGD2918rw8

@kostascrypto builds key agreement from hashing. (Impractical so far, someone please fix.)

Soon cryptography = hashing, and everybody can understand cryptography again.

[Flint Trade @flint_trade_]

Flint runs a propAMM on-chain.

propAMMs have taken real share of Solana spot volume for a simple reason: the maker owns the inventory and the quote, instead of a passive curve owning both.

@thedavidgorski breaks down how they work 👇

[HumidiFi @humidifi]

if your defi application does not have a defense against downtime, it should. LastRestartSlot is a sysvar available to you on Solana (born during the tough times)

humidifi pools are automatically disabled on restart (Fig 1)

borrow/lend venues and perps dexes can disable withdrawals for a short period after a restart

[u8 @atarashi]

Currently only 3 out of these propAMMs appear to have defense against a cluster restart.

Worth adding if you haven't already!

We just open sourced the code-simplifier agent we use on the Claude Code team.

Try it: claude plugin install code-simplifier

Or from within a session:
/plugin marketplace update claude-plugins-official
/plugin install code-simplifier

Ask Claude to use the code simplifier agent at the end of a long coding session, or to clean up complex PRs. Let us know what you think!

[Triton One 🌊🌋 @triton_one]

We know writing a Solana TPU client from scratch is really hard. Handling Agave releases, QUIC quirks, and leader schedule tracking needs constant maintenance.

And while tpu-client-next is a big improvement, some builders still need more control than the standard client can provide 🧵👇

[Ellipsis Labs @ellipsis_labs]

Today, we’re introducing Phoenix Perpetuals, an on-chain perpetuals exchange built on Solana.

[Space Monkey @RealSpaceMonkey]

This is a long post about the rise of "prop AMMs", the history behind them and their advantages/disadvantages. This post will be different than my usual style of trying to be concise and is more of a story since it was meant to be for a DeFi Day talk like I did in the past 2 years. Unfortunately, this year I was asked to provide my ID/KYC (not the fault of the organisers) to be able to speak which I'd rather not do.

As a gift to the Solana community for Breakpoint 2025, we've decided to open-source `peephole` https://t.co/NVGSJ9ve62

peephole: Zero-copy account parsing for Solana programs

solana_program::entrypoint::deserialize allocates `AccountInfo` structs and copies account data. peephole skips that with a zero-alloc and zero-copy view over the account and instruction data.

Real-world: 51 CU oracle update, 67 CUs for 3 oracle updates, 12 CU trading contract, and many others.

Introducing: Drift v3

Drift has built through bull and bear to deliver one thing: a better trading experience.

Today, Drift v3 goes live. A modern redesign with 10x faster execution.

Built to outperform.

HumidiFi swap instruction data obfuscation:
- In-place XOR-based stream cipher.
- Symmetric (f(f(x)) = x) and operates on 64-bit chunks.

Algorithm:
- Process data in 8-byte (u64) chunks.
- For each chunk:
-- XOR with static `HUMIDIFI_IX_DATA_KEY`: [58, 255, 47, 255, 226, 186, 235, 195, 123, 131, 245, 8, 11, 233, 132, 219, 225, 40, 79, 119, 169, 121, 169, 58, 197, 1, 122, 9, 216, 164, 149, 97][0..7];
-- XOR with rolling `pos_mask` (starts at 0, increments by 0x0001_0001_0001_0001 per chunk).
- Remainder handling (if len % 8 != 0):
- Zero-pad remaining bytes to 64 bits.
- Apply same XORs (key + current pos_mask).
- Copy valid bytes back to original slice.

Input Layout (after deobfuscation):
- Bytes 0-7: `swap_id` (u64)
- Bytes 8-15: `amount_in` (u64)
- Byte 16: `is_base_to_quote` (u8)
- Bytes 17-23: Padding
- Byte 24: Selector (popped before deserialization)

[Solana @solana]

Every asset.

Available at launch on Solana.

[Alessandro Decina @alessandrod]

we do 100k TPS and feel deep dissatisfaction

you do 19k TPS with creative crypto accounting across 50 chains and celebrate

we are not the same

[Harmonic @harmonic_gg]

Today we’re launching Harmonic, an open block building system optimized for validator revenue and throughput, built to make @solana faster, fairer, and more competitive.

Solana wins with performance and open, fair markets.⤵️

Now might be a good time to say: @blueshift is a self-funded open source company. If you’d like to see us spend more time on education and tooling than devshop work to bootstrap our mission of accelerating the shift to Solana, you are more than welcome to support us! 🙏🏻
