#OpenSource tools and infrastructure for #Cardano blockchain developers. We focus on integrating on-chain data with off-chain infrastructure.

Last week taught us that being a Cardano SPO is no walk in the park — 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 🧵👇

Cardano & Bitcoin are a great match 🫶 Many teams are exploring novel ways to bridge assets & data between the chains. Our focus is on a different kind of bridge... A developer bridge — a shared developer experience across both chains. Same tooling, less context switching 🧵👇

Go to a Cardano explorer, grab any Tx. Can you tell what's doing? A big problem with UTxO is that there's no well-defined interface, nothing to describe a dApp from the user's perspective. Tx3 provides a new language for describing transactions as functions with intent.

Is Tx3 a smart contract language? No. Tx3 is a abstraction layer above the UTxO validators that run on-chain. It describes the interface for your dApp as a whole. In EVM they have something similar, the ABI. Think of Tx3 as the OpenAPI for UTxO protocols.

There are already 31 ships competing to reach the 10k ADA locked in Asteria. The top 3 are within a 21 step radius of the goal. Are they going to make it? or will they run out of fuel before that? 😬

Testing UTxO protocols has always been a pain-point. Tx3 has a nice feature called ephemeral devnet. Define initial balances for your test wallets and then run trix devnet to start a single-node network that goes back to its initial state after each restart.

Wen a full-node in Rust? A full-node requires a huge development effort, much more than what TxPipe can provide by itself. That's why we're joining efforts with other teams in the ecosystem via the recently announced @pragma_org, to collaborate on a new ambitious project: #Amaru. The building blocks developed for Dolos will be used as foundation for #Amaru. Dolos will evolve side-by-side as an efficient backend for dApps while Amaru's end-goal is to become a block producer / relay node that can be used by SPO. By reusing the same building blocks in both projects, improvements on one will benefit the other. 🤝
