One block has to be a reference to the other to become valid and subsequently to make the chain as a valid blockchain.</p>\n<p>So if there are two parallel blocks generated, then the next block has to be on the top of either of the two. Once a block is mined from either of these two, the other block will become a \"orphan\" block, as it will not constitute a part of the longest chain and longest chain is the valid chain. </p>\n<p>A blockchain works under the whisper principle. means each block whispers to the other nearest block and the process continues and in the entire process a block becomes a reference to the next block and hence the formation of chain takes place. This principle is made to ensure there is no double spending.</p>\n<p><br></p>\n<p><br></p>","appDepth":2,"appParentPermlink":"fka9y6ayw","appParentAuthor":"milaan","musingAppId":"aU2p3C3a8N","musingAppVersion":"1.1","musingPostType":"answer"}" |
