- What happens in the bitcoin network when two miners solve a block at the same time?
- the one with more nodes joining wins.
- What is a stale block?
- a valid but dropped block because of its shorter chain.
- How do stale blocks occur?
- when a block loses competition because the total size of the blocks is less than the competing blocks. Stale blocks are put back into the Mempool.
- Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction?
- A completed block needs time to be propagated throughout the world.

What happens in the bitcoin network when two miners solve a block at the same time?
A fork occurs temporarily. Both blocks are being propagated through the network. Other miners can add blocks to either of those two blocks until one of those two blocks becomes part of the longest blockchain (in terms of difficulty). In that case the longest blockchain will survive and the other blockchain is being dropped and becomes a stale block. All TXs of this stale block will return to the mempool. -
What is a stale block?
A block that was dropped from the blockchain after a fork occurred. -
How do stale blocks occur?
If two blocks were added to the blockchain at the same time, the fork that becomes the longest blockchain will survive. -
Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction?
As a rule of thumb it is good to wait for 6 confirmations to make sure that the block your transactions is in does not become a stale block.

They are both added to the network
2. What is a stale block?
a valid block that has been removed from the blockchain
- How do stale blocks occur?
When two miners solve a block at the same time. Both blocks are added to the network but are picked up by different nodes and then the blockchain will be temperairly different. the miner that adds the next block to the chain will have more Pow therefore the blockchain will be dropped from the network.
- Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction?
as your block could be a stale block meaning your transcation will be thrown back into the mempool

- both will be added to the blockchain at the nodes nearby. so there will be two different versions of the blockchain for a certain time
- it is a validated block but not finally confirmed
- it is a validated block of a concurrent blockchain which is shorter than the other and therefore it will be made invalid and it transactions go back to mempool
- your past transaction could be left unconfirmed until then

- The block in the longest chdain wins and the other block is discarded.
- A stale block is a once valid block that gets dropped because there is another version of the blockchain that is longer.
- Stale blocks occur when 2 blocks are produced at the same time.
- The best practice is to wait for 6 more blocks to come after your block, to be sure that your transaction is in block that is not dropped.

What happens in the bitcoin network when two miners solve a block at the same time?
the chain is divided in 2 and the one with the longest chain wins and the other one goes to the mempool.
What is a stale block?
is when a block is mined but is later excluded from the best blockchain because they were immediately overridden by a longer chain.
How do stale blocks occur?
occurs when two miners produce valid blocks at similar times or there is communication delays within the data transfers of computers across the world.
Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction?
because we need 6 confirmations to be sure that the block your transactions are in is not dropped from the chain.

One will be dropped eventually. The block with more subsequent blocks showing pow.
Stale blocks are unused. All transactions return to me pool.
When one chain wins over another.

Q: What happens in the bitcoin network when two miners solve a block at the same time?
A: They both get added in the block in different links. Whichever the other miner chooses to link their block with will stay in the blockchain and the other will get dropped. The longest chain will always win. All the transactions of the dropped block will go to the mempool.
Q: What is a stale block?
A: A block that was once in the blockchain and got dropped later.
Q: How do stale blocks occur?
A: When two miners solve a block at the same time there are two versions of truth. Due to that the next block that will be added to the chain and will make one of the chains longer that will be the version of the truth. The other block gets dropped from the blockchain and that is the stale block.
Q: Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction?
A: To see in case of the block getting dropped and becoming a stale block.

The nodes closer to the miners start propagating their own version of the truth or of the blockchain until one of those 2 different truths becomes obsolete by the other collecting more blocks from other miners as the blockchain accepts the chain with the highest number of validated blocks as truth. The nodes that propagated the āwrong truthā in that case just accept the new version of the truth and follow along while the other block gets dropped out of circulation and its transactions return to the mempool.

A stale block is a validated and truthful block which got rejected from being included in the blockchain due to another block having a longer chain .
-
From the incident of 2 or more miners solving a block at the same time and propagating their own version of the truth. One of the blocks will be seen as āthe truthā and it will be the one which will manage to form the longest chain. The ones who will get rejected for having a shorter chain will be taken out of the circulation and their transactions returned to the mempool. These rejected blocks are called stale blocks.
-
To make sure that your transaction will not be in a stale block which will then be returned to the mempool.

- The next corresponding block will choose which block to take, there can only be one version of the truth.
- A stale block is a block that has been dropped because of a newer version.
- Stale blocks occur when there are two versions of the same block and a next block is chosen. It is important that when you have a confirmed block, you should have 6 more corresponding blocks.
- It is important so that you can avoid stale blocks.

It produces two diferent versions of the chain until the rest of the miners confirm wich is the longer chain and valid - What is a stale block?
Its a block that was temporaly valid but it was droped because there was a longer chain produced at the same time - How do stale blocks occur?
When two miner validate two diferent blocks at the same time - Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction?
Because the chain of blocks is producing blocks every 10 minits leaving time for it to propagate the new block to the rest of the network, if you dont wait for at least 6 confirmations theres stil chance for the block where your transaction was to be droped and your transaction rejected

- What is a stale block?
- Stale blocks are blocks that are dropped because there is a longer version of the blockchain that was confirmed and used. Stale blockās transactions gets returned to the mempool.
- How do stale blocks occur?
- Stale blocks occur when 1 version of the blockchain did not mine fast enough hence resulting in shorter chain which eventually gets dropped.

Both miners will begin to propagate their blocks through the network, eventually one of these will be accepted, and the other will become stale.

A stale block is a valid block that has been abandoned, and the transactions of that block return to the mempool.
-
Stale blocks occur when there is more than one valid block propagating through the network at the same time, but there is only one version of truth, so by chance the block becomes stale because nodes on the network eventually synced and accepted the other valid block which was propagated at the same time.

1. What happens in the bitcoin network when two miners solve a block at the same time?
A. The chain temporarily forks into two valid branches but only one them will prevail as the longest chain is preferred and the one with the most attached blocks wins. The transactions into the loosing chain will return to the mempool.
2. What is a stale block?
A: A block removed from the blockchain as its fork was rejected.
3. How do stale blocks occur?
A: They occur whenever a fork in the network is created as a result of more than one miner successfully get the PoW for their block before the information fully propagates through the nodes of the network. The fork that gets the most blocks attached (another way of saying that they involve the largest PoW) to will win and the ones on the loosing fork will the rejected by the network.
4. Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction?
A: Since a fork can always occur, this is the only way of ensuring that the block the transaction is recorded into is not going to become a stale block

1- The blockchain is split into two verified chains.
2/3- When the blockchain is split because of two blocks being upended at the same time the network has to choose a true chain. When a chain is added to and has more Pow then that chain is taken as truth and the other block is discarded and known as a āstale or orphaned blockā.
4- Waiting for at least 6 blocks to be confirmed is important because if the network hasnāt completely synced and totally accepted the chain your block happens to be in as the true chain the block can still be dropped and your transaction sent back to the mem pool.

- 1 If the two miners each have a valid block, they will append them to the blockchain and propagate them to the network. As a result, there will be two versions of the bllockchain. The version to which the next block is appended, will be the valid one. The other version will be dropped.
- 2 A stale block is a block that was dropped because the network decided to keep working on another version of the blockchain.
- 3 Stale blocks occur, when two miners each append a block to the chain, which will cause a fork. The next miner creating a block will choose one version of the chain to append his block to. That chain, as a result, will be longer than the other and thereby be the one everbody will kepp adding to.
- 4 To make sure that your confirmation didnĀ“t come from a future stale block.

They both get appended to the blockchain but the next miner chooses the one now with the longest chain as the truth based off PoW.

Stale blocks are blocks that were in the network for a period of time but later dropped and became invalidated after losing to the other block with the longest chain.
-
Stale blocks occur when the next miner chooses the block the āstale blockā competed with as the only form of truth, kicking the āorphanā block out of the network and back into the mempool.

Because 6 confirmations ensures the security of the block staying in the network. Even after your block has been appended to the network there is still a chance of the block being dropped so 6 other confirmations ensures it stays valid.
