Last week taught us that being a Cardano SPO is no walk in the park β€” managing infra is complex. What happens when we add 10 partner-chains Midgard Hydra bridges oracles? How do we unify operations without compromising decentralization? Enter: SuperNode πŸ§΅πŸ‘‡

To all Cardano dReps, Thank you for participating in the Intersect 2026 governance budget process. We know this was a huge amount of work. Reviewing dozens of proposals, understanding the trade-offs, and casting informed votes takes serious time and dedication. We're grateful to every single one of you, regardless of how you chose to vote. The process only works because dReps show up and engage thoughtfully. We're very happy with the results so far. We still need to wait for the on-chain phase, but the support we've seen already makes the entire TxPipe team incredibly proud and more energized than ever to keep building for the ecosystem. Thank you again πŸ™

@txpipe_tools came by our office yesterday and we talked a lot about ZK and the future of web3. Always great to exchange ideas with like-minded builders Thanks for stopping by, guys!

Santiago Carmuega (@santicarmuega) joins us for a technical deep dive into Dolos, a lightweight Cardano data node alternative built completely in Rust. πŸš€ This Developers Office Hour breaks down TxPipe's design philosophy and architecture for optimizing ledger data access: β€’ The Data Node Role: Bypassing heavy consensus validation to optimize for fast, resource-efficient ledger queries. β€’ Rust Infrastructure: Leveraging a modern performance-first tech stack built on top of Cardano open protocols. β€’ Lightweight Use Cases: Overcoming standard node hardware limitations for client-side applications and indexers. Check out the documentation and open-source repositories mentioned in the session: πŸ”Ή Dolos Docs: docs.txpipe.io/dolos πŸ”Ή GitHub Repository: github.com/txpipe/dolos πŸ”Ή Subscribe to the calendar: addevent.com/calendar/TG8072…

Dolos might just be the most important Cardano infra software that no one talks about.
We usually describe Dolos as a "Data Node". Although accurate, it's easier to think about it as a DB-Sync alternative. As with everything, each option has its trade-offs. Here's a technical comparison between the two. 🧡

UTxO RPC gets sharper: certificate pattern matching in the watch service dump history calls now honor height & hash params. TRP UTxO mapping now populates reference script expressions. Plus various bug fixes under the hood. github.com/txpipe/dolos/rele…

4/ Load Balancing - DB-Sync: Scale up multiple PostgreSQL database read-replicas; distribute users across the cluster. - Dolos: Scale up Dolos replicas horizontally; load-balance HTTP requests.

That's the gist! To learn more, or to try it yourself, head to the Dolos repo. Please give us a ⭐ while you're there. github.com/txpipe/dolos

Another protocol in the Tx3 registry to check out: GitHoney Bounties. GitHoney runs open-source bounties on Cardano: fund a GitHub issue, a contributor gets assigned, and they claim the reward once it's merged. A quick look 🧡 tx3.land/protocol/open-tx3/g…

Use the Tx3 codegen feature to turn the GitHoney Bounties protocol into a typed client library in TypeScript, Rust, Go or Python. Each transaction in the lifecycle becomes a typed function call.

Assuming the item was linked to an NFT, both @nmkr_io and @AnvilDevAgency have APIs to both issue the tokens and update the metadata of said token. If the token itself is not majorly critical because you are not actually transferring the ownership of the token from person to person, you could accomplish similar with a registered address datum or metadata format and just update the on-chain record. Tx3 by @txpipe_tools could help here as it makes it relatively trivial to describe what actions you're taking in close to "plain language" while obfuscating a lot of the UTxO complexity

Another protocol in the Tx3 registry to check out: Strike Staking. @strikeperps is a decentralized derivatives platform. STRIKE is its governance token, and you can stake it on Cardano to earn a cut of trading fees. A quick look at the protocol 🧡 tx3.land/protocol/open-tx3/s…
