f(x)Core Mainnet Validator Updates

Hi, we encourage testnet validator to practice the upgrade so their validator can go active on testnet and more confident during the actual mainnet upgrade

And also, considering that it is only a test network, in order to avoid waste, we stopped some validators before

current testnet version:

root@iZt4n33wlmxjat4hgxnkr7Z:~/.fxcore/config# curl -s localhost:26657/abci_info|jq
  "jsonrpc": "2.0",
  "id": -1,
  "result": {
    "response": {
      "data": "fxcore",
      "version": "release/v5.0.x-v5.0.0-rc0",
      "last_block_height": "9831098",
      "last_block_app_hash": "4ns7wwBna7uf2OxG+6/W5jyLWS8gMBqRHmvWlbVBPlE="

Hello @FrenchXCore ,

  1. If the server is hacked or the consensus public key is leaked, the validator’s consensus public key can be replaced by sending a tx to update the consensus public key
  2. Authz module allow us grant privilege to a new wallet address, so the new wallet address can send transaction on behalf of the old wallet, old wallet will be disabled. It is not recommended to use this if the validator private key is not leaked

We’ll be updating the gitbook for these new features soon…

Dear FX Community,

We hope this message finds you well. As part of our ongoing commitment to maintaining a secure and efficient validator network, we have some important updates to share with you today.

Validator Retirement:

In our continuous effort to optimize the validator network’s performance and ensure that we maintain a high level of security and reliability, we have decided to retire a select number of active validators. This decision has been made after careful consideration and evaluation of the network’s overall health.

Shutdown of Inactive Validators:

Additionally, we will be taking steps to shut down our few validators that have been inactive for a considerable period of time. This action is aimed at freeing up network resources and ensuring that delegations and funding are effectively distributed to active validators.

Impact on the Remaining Validators:

We understand that this decision may raise questions about how it will affect the validators that remain operational. Rest assured, the delegations and funding from the retired and inactive validators will be reallocated to the remaining validators. This will not only enhance the overall performance of the network but also strengthen the validators’ capabilities to provide consistent and reliable service to our community.


We are currently finalizing the list of validators to be retired and the timeline for these changes. We will provide you with a detailed schedule in the coming weeks, so you can anticipate these adjustments.

Community Feedback:

Your input is invaluable to us. We encourage you to share your thoughts, questions, or concerns about these changes in the comments below. We will do our best to address any queries you may have.

We believe that these actions will contribute to a more robust and efficient validator network, which will ultimately benefit the entire FX community. We appreciate your ongoing support and trust in our commitment to maintaining a secure and reliable platform.

Thank you for being a part of our journey towards a stronger and more secure FX validator network.

Best Regards,


This is a very important step…
To promote decentralization, to value public involvement, to show a part of the foundation’s path for the future.
Thanks @lancelai !
