Questions on: timestamp

The first confirmation was in block 298902, so the third confirmation was with block 298904, which is timestamped as 2014-05-03 09:42:49 (66 minutes after it was first received). However, this timestamp is later than the one in the block after it, su
One cannot damage history, because history cannot be changed. I went back in time to steal this because history says it disappeared. And history says it disappeared because I went back to steal it
NTime is the integer timestamp in seconds. It is one element on the block header. Each second NTime increases by one
Transactions don't have a timestamp. Blocks have a timestamp. The difference is important, because the block timestamp on some of the blocks changes the difficulty
From what I understand, the difficulty required by the proof-of-work in bitcoin is a function of block history, specifically the average time between last ~2000 blocks, with the intention that its hovers around the 10 minute mark. The function relies
But the timestamp (block header field) is hashed? How is that useful to the blockchain? Surely the time the new block is announced to the blockchain is the time value that is recorded? – AnonymousAug 27 '13 at 13:23 @Anonymous: The network isn't a mo
From this blog post describing the timejacking attack: Each node internally maintains a counter that represents the network time. This is based on the median time of a node's peers which is sent in the version message when peers connect. The network
2 previously introduced mempool-only locktime enforcement using GetMedianTimePast(). This release seeks to consensus enforce the rule. Bitcoin transactions currently may specify a locktime indicating when they may be added to a valid block
Scenario: Michael receives 0. 05000000 BTC from Pablo and another 0. 01000000 BTC from Kuradang
The root cause of this is that without a central authority, it's impossible to know for sure what the current time is. The protocol rejects blocks with a timestamp earlier than the median of the timestamps from the previous 11 blocks or later than 2
