Waiting for more confirmations won’t avoid stale blocks from happening. But it will decrease the chance of our transaction being in a stale block.
Yes, we need at least 2 or more miners to solve a block at the same time.
They propagate throughout the network. Because of internet delay, we have a situation in which we have 2 different truths. If internet had less delay, bitcoin+s blockchain first layer would be more faster.
We have a fork when 2 miners find a block at the same time. Then the longest chains eventually overtakes. What about the fourth question?
-
What happens in the bitcoin network when two miners solve a block at the same time?
This creates a temporary chain, the miner that continues and creates the longer block chain will be adopted and the other will be dropped (stale or orphaned). -
What is a stale block?
A stale block is a block that is a apart of a shorter chain that eventually gets dropped and not adopted into the validated chain. -
How do stale blocks occur?
stale blocks are created when two miners mine a block at the same time, once the a chain becomes larger then the other -
Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction?
This allows for the possibility of your tx to be confirmed and accepted instead of being apart of a stale block chain and dropped.
-
Both blocks are sent through the network to the nodes as both are valid. Over time as other blocks are validated, the block that is the longest will earn consensus and become the valid block.
-
A valid block that was once on the network but has since been dropped.
-
A stale block was a valid block that was accepted into the block chain at the same time as another block but the stale block ends up being discarded because it didn’t end up on what became the longer chain.
-
You gain greater validation and as such lessen the chance of being discarded as a stale block.
- Both are added for the time on the chain, eventually the longest block wins and the one that doesn’t all transaction are returned to the mempool.
2)A block that is dropped from the chain because another block is longer.
3)Two blocks from 2 different miners get added at the same time. eventually one has to be dropped. That is a stale block. - It is important so the network can confirm.
- When 2 miners solve a block at the same time the block in the longest chain wins and the other block is discarded and considered a stale or orphaned block. All the transactions are returned to the mempool.
- A stale block is the block that was in the blockchain but then dropped because another block that was produced at the same time was part of a longer chain.
- Stale blocks occur when a block was valid for a while because 2 were produced with the same version of the truth but then dropped because the blockchain continued on another block.
- It is important to wait for 6 confirmations to be sure that the block your transactions are in is not dropped from the chain.
-
When 2 miners solve a block at the same time, they will each start propagating their block to nearby nodes. Therefore, some nodes will one version of the block, some will have the other. When a new block is created, the miner will choose which version of the chain to append. The block the new miner chooses stays in the chain, and the other is sent back to the mempool.
-
A stale block is a block that was in one version of the blockchain for some time, but is eventually displaced by a more widely accepted version of the chain.
-
Stale blocks occur when the block time is too fast, and you have multiple miners solving multiple versions (or hashes) of the same block.
-
You should wait for 6 blocks to be confirmed beyond the block with your transaction so you know that you are seeing the most widely accepted version of the blockchain.
- Only blocks with most proof of work would be added to the blockchain, meaning only one of the miners is going to win.
- The blocks that didn’t get at least 6 confirmations from the nodes on the network, therefore been drooped with all transactions invalidated and back in mempool.
- In the shortest chain created, version of the truth would be rejected, network will only accept version of the truth in the longest blockchain.
- To make sure block with transactions doesn’t get dropped and become stale.
- The chain forks temporarily
- A block that gets put back into mempool in favor of chain with more POW
- Stale blocks occur after a fork is resolved with a longer chain
- In case of a stale block occurring.
- It effectively splits the blockchain in two and both blocks are valid at this stage
- a stale block is one that has been dropped by the blockchain network where previously it was in contention to be confirmed
- a stale block occurs when another valid block is favoured due to a longer proof of work
- waiting for more than one confirmation, preferably six means that block is less likely to be dropped
- Both block get added to the blockchain. Some nodes will get the info that block a got added and other that it was block B. the next round of block adding will determine which chain / block will be dropped due to its shorter chain.
- Stale block is the name for a block that has been temporarily added to the blockchain and later dropped due to the reason explained in 1.
- They occur when to blocks get mined at exactly the same time and therefore two blocks get added simultaneously to the blockchain.
- to make sure that your confirmed transaction isn’t accidentely sitting in a stale block that will not be part of the blockchain moving forward but will be dropped
1.One will eventually have another block added to it. Whatever block is longer will be the one accepted to the network.
2. A stale block is the one thats not accepted and tossed back into the mempool.
3. A Stale block occurs when two blocks are solved at the same time. The block thats NOT added to the chain is the stale block. Basically its 2nd place or the loser block.
4.To confirm that the block is truly accepted.
1. What happens in the bitcoin network when two miners solve a block at the same time?
There are two version of the blockchain each containing different last block. These will be broadcasted to the network and miners at some point will choose one of the two newly mined blocks to build a new block. The longer blockchain is chosen and the other block from the shorter version of the chain is then considered orphan. Transactions from this block will be added to the mempool.
2. What is a stale block?
As per above.
3. How do stale blocks occur?
When miners solve the cryptography puzzle in the same time. One block is chosen to be appended to the blockchain, the other will be stale.
4. Why is it important to wait for more than one block to be confirmed when sending or receiving a transaction?
Due to the fact that the transaction which has only one confirmation can be a stale block.
- The block in the longest chain gets accepted, and the other block gets stalled.
- Stale block is block that gets dropped because the other block that was produced at the same time gets part of the longer chain.
- Occurs when 2 blocks were produced at the same time, but the other block wins because it becomes the part of longer chain.
- Because your transaction can be a part of the block which might be stalled in the future, because there might be another block that can win or become valid by being in the longer chain.
- when 2 miners solve a block at the same time the on with the longest blockchain wins. The loosing block becomes orphaned and goes to the mempool.
- an stale block or orphaned block goes back to the memepool
3.There can be only one truth . - The whole chain needs to confirmed by the network to ensure the blocks are correct
1.The miner that produces the block after that determines withc block will be added to the blockchain. Because it will use one of the two blocks as its truth
-
The block that was on the network but later dropped.
-
Wenn two blocks come out on aproxatley the same time. There will be only one block that will be added on the blockchain defitnitely. The other block will be dropped and is called a stale block
-
Because of the time it takes to Physically send the wright information to all nodes across the world
- They will both broadcast their blocks to the network.
- A stale block is one or more blocks that are not part of the longest chain.
- When two or more blocks are solved at or around the same time they start propagating the chain as they see it. At this point, we have 2 sources of truth. The network will eventually use the longest chain and the shorter will be the stale blocks and those will be removed from the network.
- Because you might be on a stale chain.
- The block spreads through the network until a miner picks up either and adds a new block. Then the block on the shortest chain is dropped and transactions are returned to mempool.
- It is a block that has been dropped from the blockchain.
- When network confirms that block is not present on the longest chain.
- So that there are no stale blocks.
