Latest SDK and Middleware Update
Over the past month æternity was working on several SDKs in order to provide a smooth developer onboarding experience. The main goal was to provide a unified and clear way to perform actions on the æternity platform. For the sake of full transparency, we are sharing a detailed update about the work of the æternity SDK development teams. Find it in the Status-quo Update below.
Currently, the æternity SDK team is managed by Andrea Giacobino
The Python SDK will be updated in order to support State-Channels, as requested by the community. This is the current highest priority task, followed by support for the new compiler.
The product manager for the Python SDK is Andrea Giacobino
The Go SDK will be shipped with support for Oracles implemented. it will be able to listen to the Noise Protocol for queries and respond to queries. A tutorial æpp will be built to showcase Oracle features. The long term goal of the Go SDK is to be transformed into a development framework that provides Oracle services and improve the general usability of the Oracle feature.
The product manager for the Go SDK is Andrew Chiw
The public æternity infrastrucutre is powered by the æternity Middleware. In the upcoming weeks the Middleware will receive major updates that will enable subscribing to events, a reverse name lookups, calculation of GasPrice/Tx Fee (an average over certain amount of transactions enabling dynamic minimum fees for æpplications and wallets) and call data decoding.
The product manager for the æternity Middleware is John Newby
Hosted Middleware for Testing (experimental)
æternity plans to provide hosted infrastructure for developers and businesses similar to Infura and Alchemy. We will continue to host such a service for testing but the long term goal is to support an independent team to run and maintain such a public infrastructure as a business. Instead of interacting directly with nodes, æternity’s hosted infrastructure will be faster, reliable and scalable, so developers can focus on building a product. The infrastructure will be powered by the Middleware.
Public Endpoints (DON’T USE IN PRODUCTION):
The æternity SDKs ecosystem features three access levels to the æternity blockchain functionalities:
- command line interfaces (cli)
- web tools
The cli (2) access level provides a stable access to the public (external) functinoalities.
The web tools (3) are verticals developed for specific functionalities.
The programmatic (1) and cli (2) levels are accessible via software libraries.
The official SDKs libraries are:
The different SDKs serve slightly different purposes.
The JS SDK is mostly intended for embedding in web applications. As a result the cli (2) access is separated from the programmatic (1) access. For the same reason, the JS SDK provides advanced security measures (guards) to prevent the involontary mis-use of node functionalities (TODO: verify)
The Python SDK is intended for implemenentation reference and for fast prototying of server side services. It bundles the programmatic (1) and cli (2) access levels together.
The Go SDK is the preferred SDK for CLI usage and for production systems where performance is important. It bundles the programmatic (1) and cli (2) access levels together.
Web Tools (soon to become part of the Dev-Suite)
The web tools (3) use the JS SDK under the hood. They include:
- Contracts - dedicated to the interactions with contracts. Will become part of the Dev-Suite Playground æpp.
- Goggles - usd for inspecting and validation of transactions, as well as verification of signatures. Goggles will also become part of the Dev-Suite Playground æpp.
- Playground - a Browser IDE for quick testing and development. Playgorund is part of the Dev-Suite.
Web tools (not to be developed further)
- Explorer is for blockchain monitoring and exploration. We recommend using the community-developed AEKnow explorer.
Dedicated to Testnet there is instead:
- faucet.aepps.com to top up an account on the Testnet.
- Middleware high troughput æternity node query engine.
