When the roar of hardware intertwines with the logic of code, and you are ready with the furnace of power and the cornerstone of identity, you welcome the most solemn and sacred moment of the entire journey: registration. This is not a simple information registration, but a digital world's coronation ceremony. Through it, you will officially bind your EigenLayer identity deeply to the Lagrange network, declare your role as a core contributor, and engrave your commitment in a cryptographic form on an immutable smart contract.
Step One: Minting the Staff — Generate Your Lagrange Exclusive Key
In the realm of Lagrange, every operator must possess a dedicated 'staff' — an ECDSA key specifically designed for operations on the Lagrange network. This is not a redundant design, but a thoughtfully considered security philosophy.
We understand that in a complex operational environment, the simplicity and security of key management are crucial. Therefore, under the current architecture, all provers under a single operator can share the same Lagrange-exclusive key. The brilliance of this design lies in its complete isolation of the risks associated with daily operations from your core identity (i.e., EigenLayer master key). Even in extreme cases, if this exclusive key were to be unfortunately leaked, there is no need to panic. Simply deregister the old key in the Lagrange network swiftly, and re-register a new key to restore the highest security state of the network, while your EigenLayer foundational identity remains intact.
The ritual of minting this staff is extremely concise:
docker compose run --rm worker avs new-key
The system will guide you to set a dedicated protection password for this new key. Once completed, an encrypted keystore file will be quietly generated. The public key contained within, like the unique emblem on your staff, will become your public identity on the Lagrange network.
Step Two: Sacred Covenant — Announce Your Joining to the Network
Now, you hold two tokens: the first is the 'master key' generated during your registration with EigenLayer, representing your fundamental credibility; the second is the 'dedicated staff' recently minted, representing your duties in the Lagrange network.
The next ritual is to present these two to the highest laws of the network — smart contracts, to complete the final binding of identity. This process will simultaneously declare to the EigenLayer contract system that you are serving Lagrange AVS, and inform the Lagrange contract system of the exclusive key you will use.
Please place the operator master keystore file generated by EigenLayer CLI in the designated location. Then, execute this sacred proclamation command:
docker compose run --rm worker avs register
This is a moment worth remembering. The binary program of Lagrange will only need to read your master key at this moment to complete the signature verification. It will not store this key, which represents your supreme credibility, in any form. After the ceremony, you can and should immediately remove it securely from the configuration folder for safekeeping. Your core identity will henceforth be worry-free.
To ensure that the entire registration process can smoothly access the encrypted key, please export the password you set as an environment variable.
Step Three: The Whisper of the Law — Insight into the Logic Behind the Contract
For those wise individuals eager to explore the essence of things, let us take a glimpse at the underlying laws driving this ceremony. In the smart contracts of Lagrange, the `registerOperator` function is at the core of this coronation.
`function registerOperator(PublicKey calldata publicKey, ISignatureUtils.SignatureWithSaltAndExpiry calldata operatorSignature)`
`publicKey` parameter is your newly minted Lagrange exclusive public key, presented in its purest mathematical form (affine coordinates). The `operatorSignature` is the finishing touch of this covenant. It is a digital signature generated by your EigenLayer master key, meeting its strict standards. This signature acts like a respected recommender, solemnly guaranteeing the legitimacy and authority of the new identity to the entire network.
When the transaction is on-chain and the function execution is complete, your 'digital coronation' is officially accomplished. Your identity is no longer just an address, but has become an active node that is officially recognized, endowed with rights and responsibilities, and protected by economic laws within the Lagrange network.
