- One of them will be dropped and go back to the mempool. They are called stale/orpahened blocks.
- A stale block is a completely valid block that has been dropped, it hasn’t been added to the blockchain.
- Stale blocks occur if the blocks are added to the blockchain too fast.
- Because the network always choose the longest blockchain with the best POW. 6 blocks are necessary to confirm the transaction.

There will be 2 versions of truth circulating in the network and once another miner comes in the longest version will win -
What is a stale block?
A valid block that was once on the blockchain but then got dropped as there is another version in the blockchain that is longer without that block in it -
How do stale blocks occur?

Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction?
To be sure that the transaction is in the longest version of the blockchain instead of one of those stale blocks that will be dropped

- The blocks will be both added to the network but separate. When another miner starts to mine another block will have to attach it to the blockchain. The chain that is longer in PoW matter that one will be the one that will continue further with the chain and the other one will be dropped.
- A stale block is a block that has been taken down from the chain.
- Stale blocks occur when one of the 2 blocks with the same version of the truth is dropped from the network.
- To make sure that your block is not stale due to the network choosing the longer chain and stale your block.

What happens in the bitcoin network when two miners solve a block at the same time?
The nodes that are closes to the miner, will get different versions of the blockchain. Once a new block has been added to one of the new chains, it will make that chain the accepted one. And the other block will return to mempool. -

A) a block that is dropped from the blockchain. -
How do stale blocks occur?
A) By not getting chosen by the next miner adding its block to the blockchain. It’s the shorter chain of competing blocks. -

- What happens in the bitcoin network when two miners solve a block at the same time?
Answer: only one block becomes accepted the other block becomes a stale or orhpaned block.
- What is a stale block?
Answer: it is a block that isnt valid because another block was faster and another block was linked first
- How do stale blocks occur?
Answer: this one goes back into the memempool
- Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction?
Answer: if 2 blocks want to be attached to the chain at exactly the same time, the block that is in a shorter chain will be returned to the memempool. so it is important to wait for 6 confirmations to be sure the the block are not dropped from the chain.

Will the miner gets a block reward after confirmation that the block is not a stale block or will the miner gets a block reward after adding a block into the chain ??
The block reward is included in the block so the miner gets it as soon as it finds a new block. However block rewards can only be spent after 100 confirmations.

- when two miners solve the block at the same time, only one can win. after 6 confirmations within 10min one of these two blocks will be chosen by the next block and the other will be dropped back to the mempool

Both get added in their blockchain and are then sent to other nodes. Eventually one blockchain will be orphaned and dropped.

Stale block is 2nd version of the truth in blockchain that was dropped because of the 1st version win over blockchain.
-
Stale block occur when there are 2 versions of blocks produces at the same time and when they are added, one gets overrun since the blockchain continiued on another block on the other blockchain.
-
It is important to wait because of posibility of stale blocks occuring, its safe to wait until 6th confirmation.

The block that is first succeeded by a subsequent block will form the longer chain and become accepted.
- A stale block is one that was not the first to be succeeded by a subsequent block, and so does not become the “truth.”
They are a result of a duplication of efforts that gets propagated across part of the network.
To avoid the case where your transaction becomes part of a stale block.

They are both confirmed blocks until the next block chooses which block. The longest chain wins. This then cause one of the blocks to be dropped or stale block and put back into the mempool.

A stale block is a block that has been dropped and put back into the mempool because there was another version of truth of block that was part of a longer chain.
-
Stale blocks occur when two versions of truth are produced and put into the network. One will eventually be dropped, the dropped one being the stale or orphaned block.
-
Because the confirmed block can result into a stale block therefore it is important to wait for 6 confirmations of block.

The chain will be forked for a while until the block becomes a stale block.

A stale block is a block what got rejected by the network, the longest chain will always win.
-
If there was a fork and you have two chains now, the longes chain will win and the other will be rejected by the network. The Txs from the rejected block go back to the mempool.

- When two miners solve a block at the same time, both begin propagating on the network. There are now two competing versions of the blockchain. Once a third miner comes along and appends his new block to one of the two chains, that is the one which will be the new correct chain, accepted by the network, as it is the longest with the most PoW.

- The “stale” block is the block which is dropped from the chain that lost the aforementioned competition.
-
- Stale blocks occur when they are dropped & their transactions are returned to the mempool.

- It is important to wait for multiple confirmations (e.g. new blocks in the blockchain) to make sure, that your transaction was not in a “dropped” block and has been confirmed a few times.

Okay… Clarified. Thanks, Alko.

Different nodes might receive two versions of truth until a miner comes and links his block with one of the two.
-
Stale blocks are the rejected valid blocks from the blockchain.
-
Stale blocks occur when two valid blocks compete to be linked in the blockchain. Then a third block comes and gets linked with one of the two. The longer chain gets accepted so the unlinked block gets rejected and becomes a stale block.
-
It is important to wait for more than one block to avoid a stale block.

- When miners solve POW independently it might happen due to network latency that their block gets added to chain and there chain forks. But sooner as miners work this gets resolved by considering the chain which is highly secure.
- Stale block is which was once part of blockchain network but got dropped from chain when the other fork becomes larger with new nodes added. This chain gets break and all transaction in the block gets added to mempool.
3.Stale blocks occurs because of issues in network latency, when all nodes in the network are not in sync.
4.If transaction is added to block and if the block is in part of fork then there are chances to get the transaction moved back to mempool.

- What happens in the bitcoin network when two miners solve a block at the same time? Both blocks get added and subsequently new blocks added next to them, however, there can only be one version of the truth which is the longer chain. So the “winning” block would be one that gets other blocks added to it faster, hence it would be added to the blockchain.
- What is a stale block? A stale block is a block that gets added to the chain temporarily, however, it drops due to another competing block which is part of a longer chain through other blocks attached to it. The transactions of the stale block are being returned to the pool
- How do stale blocks occur? Explained with previous question.
- Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction? To make sure that your transaction is not part of a stale block.
