live preview of current blockchains in Bitcoin Network?

[Behrad]

As you know there might be multiple (not yet approved) chains of blocks in Bitcoin network. I was wondering if there is any online service to watch those chains being created until they are dropped (finally a solo chain, the longest, being approved by the network).

Is there such a service out there?

There are not multiple chains.
Those involuntary forks you are talking about happen when 2 miners find a block about the same time. But in the next block the situation is solved

Fork, Accidental Fork
Search
This definition comes from the technical glossary.

Definition
When two or more blocks have the same block height, forking the block chain. Typically occurs when two or more miners find blocks at nearly the same time. Can also happen as part of an attack.

very few in the last years

Personally i think  this is the best market in crypto. bitcoin transactions can be notoriously slow and expensive at times, hence the big emphasis on making the Lightning Network work. before they're processed, transactions will not be recorded on the blockchain as they can still be rejected by the Mempool if the fees are set too low. A full copy of a currency's block chain contains every transaction ever executed in the currency.

Thanks for your response.
AYK there are times when SPV mining or Selfish mning happens & some pools/miners mine empty blocks only sending block reward to their address. In such situations they don't reveal their mind blocks making a secret chain until creating a longer chain thus dropping other candidate chains after a while.

I was wondering if there is a way to watch every candidate chain being created to see which chains & which blocks were mined through a selfish style. I know its hard to address this kind of attack using current protocol state, but may be there is a way to find some solution by watching/logging & analyzing pools/miners behaviors in the past.

Thanks. I see. I'm looking for a way of recording candidate chains/blocks before being approved as valid-block/valid-chain.

I am also interested in such information, can someone still have it?

I don't think that mining an empty block can be considered an attack, neither selfish.
The miner usually just was luck and found the nonce before updating mempool data, or it may be even empty if the block is too fast. It is a run and a competition...
And imo this has nothing to do with orphan blocks (temporary side chains).

And we don't see an orphan block for years, according to blockchain.com data
