Security concerns when downloading the block chain from a 3rd party source?
Security concerns when downloading the block chain from a 3rd party source? It takes very long until bitcoin-core has downloaded the whole block chain. So I decided to download the block chain files via a bittorrent published by this website: http://ift.tt/2AmeQbY After the download was finished I noticed that the md5 checksums of the files from the torrent were different then of the files from bitcoin-core. Why could that be? Are there any security related concerns of using a block chain from a 3rd party source? http://ift.tt/2itFGKO
