The July open dev meeting started with unveiling the ongoing architecture work for integrating ZK opcodes that'll allow smart contracts on $kas, followed by a lively discussion between @hashdag, @CryptoAspect, and @dimdumon who are working on the design as well as @VolokhIlia, a guest star from StarkWare and a long time Kaspa aficionado.

Kaspa 101.
As ETHcc brought global Web3 builders to the shores of Cannes, we had the honor to host the very first Kaspa side event in France, held in the vibrant cypherpunk setting of Le Hive Bar.
The energy was real—an eclectic mix of developers, founders, investors, and curious minds gathered for an intimate and authentic experience. The atmosphere was relaxed, the discussions deep, and the vision shared loud and clear: Kaspa is building the infrastructure of tomorrow.
🎤 Keynote by Igra Labs – A Glimpse Into the Future
igralabs.com/hero
The evening was headlined by an insightful conference from Igra Labs, with Pavel, Maya, and Denis presenting their vision for programmable Layer 2 on Kaspa.
"Kaspa is a very performant Bitcoin... but it lacks programmability. That’s why we’re building Igra Network: real-time smart contracts on top of proof-of-work." – Pavel, Igra Labs
Attendees were introduced to:
Atomic composability for interacting across chains in a single transaction
Decentralization advantages of proof-of-work over proof-of-stake
The new frontier of DeFi: fair, censorship-resistant and miner-agnostic
How Igra wants to attract Ethereum builders looking for a “blue ocean”
Igra’s upcoming testnet (in weeks) and mainnet (Q4) were also revealed, as well as plans to absorb liquidity from verifiable chains like Bitcoin, Ethereum, and beyond—settling trustlessly via the Kaspa sequencer.
🧩 Open Conversations, Real Connections
Guests engaged in frank, high-level debates on the future of L2s, the broken dynamics of MEV on Ethereum, and the need for fairer infrastructure. We shared ideas on how Kaspa can reshape liquidity flows, attract developers, and unlock new UX for payments and decentralized applications.
🌱 Special Thanks
Igra Labs for sponsoring and inspiring the crowd with cutting-edge ideas.
Rhubarbarian for supporting the marketing and promotion, making this event visible and vibrant.
Le Hive Bar for providing the perfect underground energy and setting for cypherpunk culture.
This wasn’t just another meetup. It was a signal. Kaspa is ready to grow—and France is officially on the map.
Stay tuned for more. The builders are coming!

One, it is not true that fees require congestion. In fact, Kaspa's parallelism gives us great control of the threshold over which fees become meaningful. This is an important point where $kas provides flexibility where people think there is none: we can control the fee market activation threshold.
For example, in post-Crescendo TN10 we see that the merge-sets are about 4-5 blocks, meaning that 25% of utilization is more than enough to furnish an active and competitive fee market. We can arbitrarily reduce the required utilization by increasing block rates (while controlling the total throughput by changing block sizes appropriately).
Two, it is not true that the only source of security budget is fees. One instance: suppose big players use the chain to build their platforms, and their security relies on the security of the L1. In that case, it becomes their incentive to secure the network actively and not just delegate this important task to the fee market. Another instance: high BPS incentivizes service providers to create their own blocks rather than relying on miners. This means that they contribute to the security to improve their service, not for earning fees. That's another example of how the fee market is not the only source of security budget. This point would become highly relevant once countering MEV through transaction bidding is online.

The Reachability Oracle with Michael Sutton
The focus of this code walkthrough will be to get an understanding of Kaspa's DAG “reachability” layer.
The security of the Ghostdag protocol heavily relies on analyzing the connectivity of block subsets in order to identify the largest connected cluster which represents the honest majority. Throughout this search, the most fundamental question asked is whether two blocks have knowledge of each other, i.e., is there a path of DAG edges from one to another. We call this a reachability query.
Answering hundreds if not thousands of such queries per second with an ever-growing and dynamic DAG structure is anything but an easy task. Designing it in such a way that it can easily withstand 10BPS or more is a technology marvel I'm proud of being a significant part of.

Questions Asked in Chat
01:09:44:55 - 01:09:57:49
[Chat: is the reachability service "only" used when
blocks are added to DAG or even during other operations
(like querying DAG data, etc)?]
01:28:04:31 - 01:28:13:38
[Chat: when are you using delete_block?]
01:29:23:21 - 01:29:54:03
[Chat: If a majority hashrate attacker would withhold blocks up to some depth (lower than the usual reindex root depth), and then broadcast all their blocks at once (which should 2x at least the current set) how does this affect reachability intervals? What happens when blocks for a deep reorg suddenly appear]
01:31:22:02 - 01:31:35:23
[Chat: does it mean DAG reachability structure only contains the last three days blocks?]
01:36:13:33 - 01:36:26:34
[Chat: What happens to reachability queries when a reindex is occurring?]
01:39:35:27 - 01:39:49:36
[Chat: So during a reindex, is it possible that you may get an incorrect result for reachability? Since the current block being added wouldn’t be present in any current reachability interval yet]
01:49:25:26 - 01:49:38:13
[Chat: From my understanding, VSPC is a chain not tree, is the tree we talked about here the combination of (selected parent chain) for all the tips(not virtual)?]
This is TN11 Rusty Kaspa running on an 11 year old 4 core hyper-threaded CPU with 16gb of RAM, available on EBAY for under $100. To drive widespread real-world tech adoption, it's essential to prioritize compatibility with accessible hardware and minimize operational costs. Well done Kaspa Developers!"
What are Kaspa's strengths?
Kaspa is based on PoW (Proof of Work).
A brief introduction to one of the most secure blockchains in the industry.
1️⃣ Faster confirmation of competing blocks with GHOSTDAG Many blocks are generated in parallel,
Transaction confirmation is instantaneous,
Throughput and security go hand in hand!
2️⃣ Throughput up to 3,000 transactions per second. Fast block generation.
Greatly improved network capacity
3️⃣ Low cost It works on older devices, and node synchronization takes about 20 minutes, making it easy to join.
4️⃣ Shortest confirmation time: Instant confirmation with no latency.
High real-time performance
5️⃣ Log spatial protocol storage requirements are low, allowing for efficient data management
Kaspa is a next-generation L1 network that overcomes internet speed limitations
With our unique technology and architecture,
Offers scalability and stability not found in other blockchains

ABOUT KASPA
Kaspa is the fastest and most scalable instant confirmation transaction layer ever built on a proof-of-work engine. Transactions sent to miners can be included immediately in the ledger, which is structured as a revolutionary blockDAG. Kaspa is based on the GhostDAG/PHANTOM protocol, a scalable generalization of the Nakamoto Consensus (Bitcoin consensus). Its design is faithful to the principles Satoshi embedded into Bitcoin — proof-of-work mining, UTXO-formed isolated state, deflationary monetary policy, no premine, and no central governance. Kaspa is unique in its ability to support high block rates while maintaining the level of security offered by the most secure proof-of-work environments. Kaspa’s current mainnet operates with one block per second. Since the Rust language rewrite, the core developers' goal is to increase the number of blocks to 10per blocks second substantially, attracting the development of smart contracts and DeFi.
