Here's what's featured in this week's issue:
- The Cypherpunk Hackathon Product Directory is Live!
- SIMD-0385 Proposes Transaction v1
- Solana Joins the Blockchain Payments Consortium
- LimeChain Launches an Interactive Learning Platform for Solana's Transaction Lifecycle
🗃️ Cypherpunk Project Directory
The Solana Cypherpunk Hackathon, hosted by Colosseum, set a new record as the largest crypto hackathon in history with 1,576 project submissions.
Asia led global participation with 572 entries, including 224 from India, followed by strong showings from Europe, the Americas, Africa, and Oceania.
DeFi and Consumer Apps were the most active tracks, each attracting hundreds of submissions.
The hackathon’s product directory is now live, and winners, along with the next cohort of Colosseum Accelerator founders, will be announced at Breakpoint.
⏫ SIMD-0385: Transaction v1
A new proposal, SIMD-0385, introduces Transaction V1, a redesigned transaction format for Solana aimed at making the network faster and simpler to use for both developers and validators.
The current v0 format relies on separate compute budget instructions and address lookup tables, which create complexity and slow down transaction ingestion.
Transaction V1 removes both. Instead, key configuration parameters like CU limits and priority fees are moved into the transaction header, eliminating the need to parse instructions to extract compute budgets.
The new format also supports larger transactions, increasing the max size from roughly 1.2KB to 4KB. Additionally, V1 transactions no longer support address lookup tables, requiring all accounts to be listed directly to simplify validator workloads.
The changes mean more predictable behavior and fewer workarounds for configuring compute needs and represent a step toward optimizing Solana’s runtime performance.
💱 Blockchain Payments Consortium
Solana has joined the newly formed Blockchain Payments Consortium to develop shared standards for stablecoin and make it easier for crypto payments to move across blockchains and traditional finance.
Even though on-chain payments are booming (nearly $20 trillion last year), the space is super fragmented. Every chain does things differently, which makes it hard for banks and big institutions to get involved. The goal of this group is to fix that.
Solana is already a leader in crypto payments thanks to its speed and low fees, especially with things like Solana Pay. This initiative takes it a step further by working with other chains to standardize how payments work.
Solana is making sure its tech can be used at an institutional level, not just in crypto-native apps, but by banks, payment providers, and global systems.

👩🏫 Solana Educational Explorer
The Solana Educational Explorer is a new interactive tool from LimeChain that walks you through how a transaction moves through the Solana network.
You’ll get hands-on with real-time visualizations and adjustable settings to see how each part of the system responds.
The experience is broken into seven stages, each one diving into a specific part of the transaction lifecycle:
- Initiation: How dApps and wallets create and sign transactions
- Gulf Stream: Solana’s approach to forwarding transactions without a mempool
- TPU Processing: How transactions are packed into blocks
- Turbine: How blocks get propagated across the network
- TVU Validation: Consensus and vote verification
- Gossip & Archive: Finalizing and storing transaction history
- Live Demo: Watch it all happen in a real-time simulation
Whether you’re building or just curious, this walkthrough is for anyone who wants to see how Solana really works under the hood.
