Can temporary forking occur in Cardano's protocol?

That's incorrect. The ouroboros praos protocol is based on random distribution, and there's still a low probability of multiple pools being assigned the same slot. With as many slots as there are, ...

Do NIPoPoWs (Non-Interactive Proofs of Proof-of-Work) only apply to PoW blockchains or can it be applied universally to any consensus algorithm?

By definition, NiPoPoWs are lightweight proofs for Proof-of-Work blockchains. In a nutshell, they operate by taking advantage of the fact that every so often, a block of highly unusual likelihood is ...

What is block density?

Just building on top of answer from Erik, a simple way to look at it would be : (number of blocks minted so far in current epoch) / (number of slots so far in current epoch) In ideal scenario, the ...

What is block density?

Each epoch is supposed to have about 21600 blocks per epoch, where an epoch is 5 days long. If every epoch had 21600 blocks, the density would be 100%. However blocks occasionally get skipped so the ...

Can temporary forking occur in Cardano's protocol?

Cardano is a permissionless public blockchain with a fully dynamic validator set, which means that the validators/miners can join/leave the network at any time. Much like Bitcoin and Ethereum, this ...

How often do we see chain reorgs in Cardano?

On my cardano-db-sync instance I see a one block reorganisation a couple of times a day. Two block reorgs maybe once a week or month and I have never seen a 3 block reorg. That does not mean they don'...

How does Cardano technically handle reorgs?

When electing a chain at a fork, the other chain will be discarded. The chain selection is using the order below: chain length if 2 chains have a new block with same slot, then prefer block minted ...
