Transition of the Allfeat Testnet: From Harmonie to Melodie
Since its launch, Harmonie has been Allfeat's first official testnet, providing an EVM-compatible environment for developing and testing applications through the Frontier framework of Substrate. Harmonie allowed us to take the first step towards integrating an application layer, while exploring the possibility of a hybrid infrastructure combining Substrate blockchain and EVM compatibility.
However, throughout 2024, Allfeat's vision has become more precise. We have refocused our objectives on what we believe to be Allfeat's greatest contribution to the music industry: becoming a decentralized oracle for music industry metadata. This shift in focus has led to several strategic changes, notably in the technical stack and the overall design of the project.
Towards a Technological Evolution: A Layer 1 Dedicated to MIDDS and a Layer 2 for Applications
Our Layer 1 will no longer be oriented towards EVM compatibility but will be entirely focused on the registration and certification of metadata (also known as MIDDS — Music Industry Decentralized Data Structures). This refocus means that our Layer 1 blockchain, which uses Proof of Metadata (PoM) combined to Proof of Authority (PoA), will be specifically designed to serve as a secure and decentralized registry, without being disrupted by EVM contracts that could alter its functional clarity.
For application use cases, we plan to launch a Layer 2 on Ethereum, which will ensure EVM compatibility and provide an interface for application developers. This will ensure that our Layer 1 remains focused on its primary role without being potentially burdened by ancillary uses.
Introducing the Melodie Testnet: A Necessary Transition
To realize this evolution, we are pleased to announce the launch of our new testnet, named "Melodie." This testnet will represent a version as close as possible to the mainnet we plan to launch, specifically dedicated to testing MIDDS/PoM features. Melodie will allow us to test, evaluate, and improve our tools and systems before deploying them in production on the mainnet.
Melodie will also implement the work we've done in recent months on MIDDS, including its module that manages the entire MIDDS logic, which could not be implemented on Harmonie.
Once Melodie is operational, we will proceed to shut down Harmonie. But rest assured: all the airdrop campaigns organized on Harmonie and the efforts of participants will not be lost. The addresses of eligible participants have been saved, and we will ensure that rewards are distributed, even after the Harmonie testnet is offline.
The Change: A More Suitable and Clear Environment
Our priority has always been to provide a healthy and sustainable technical environment, both for our developers, our industry partners, and our community. The transition from Harmonie to Melodie is part of this ongoing effort to improve our infrastructure and ensure that every technical decision is made with the long-term vision of the project in mind.
We are confident that this new testnet will allow us to offer a better experience, closer to the final version we wish to launch on the mainnet. Melodie is the final crucial step before this transition to a stable and optimized mainnet for the specific needs of the music industry.
Your Involvement Matters
We understand that transitioning from one testnet to another can raise questions and concerns. This is why we want to reassure our entire community: your involvement and efforts will not be forgotten. Participants who have actively contributed on Harmonie will receive their rewards, as promised, once Melodie is launched.
Thank you for being part of this journey with us. The path to decentralizing music metadata is challenging, but together, we will succeed in creating a transparent, reliable, and innovative infrastructure for the future of the music industry.
