1.) epoch nonce 2.) pool's vrf key 3.) pool's percentage of overall staked ada 4.) active slots coefficient All four of these determine if a pool is allowed to mint a block in a given slot (happens once per-second on mainnet). The activeSlotsCoefficient protocol parameter is what determines that we make on average 1 block every 20 seconds. Sometimes more, ...


Cardano has three different pillars of decentralization: The first pillar: block production. Once d hit 0, this pillar was fully decentralized. The second pillar: networking. It means how nodes find each other and pass on this information. Currently, this is a topology file and it will be replaced by P2P discovery. The third pillar: governance. The way to ...


The Haskell reference implementation of the Cardano node, leaves no such decisions to the slot leader, and most (if not all) are using that node implementation. As far as the Cardano protocol is concerned, however, the slot leader could cherry pick transactions and for example prefer those with higher fees.


"Failed to start all required subscriptions" As recommended by @KC Gibson, reduce the valency for the IOHK node to two, and restart the node. The remote host is closing your connections, probably due to some connection limiting policy on their end. I recently went through a router failure and an upgrade. And with that local and external IP ...


Update 12/13/2021: My first question on Cardano Stack Exchange was What is the Penalty for Running 2 Block Producer Nodes? Which I was told, "Network can penalize." But I never received an answer as to what that penalty was, which I believe is because there is not a penalty. With that said, I believe your question is a result of a pool running 2 ...


The pool keys control the pool and can never be changed. If your pool keys are exposed, then you have lost control of your pool (this doesn't necessarily mean your pledge, but control of the fees, where the rewards go, the deposit, etc.). If you create these keys on an online machine there is increased risk of the keys being exposed, for example from things ...


There is no such penalty at the protocol level. However, you will probably get called out on Twitter :)


As long as the facility is available in the code, it is technically possible for the process to be reversed.
