Title: [2017-06-08] OpenTimestamps Has Timestamped the Entire Internet Archive Post by: bbc.reporter on June 08, 2017, 01:58:50 AM This is one of the most interesting projects ever developed in the cryptospace. It is more interesting than any ICO out there in the market right now if you ask me.
But is there any plan for the timestamp for the internet archive to be updated? I reckon there has to be. So how often do they have to stamp it and then place it in the bitcoin blockchain? https://fs.bitcoinmagazine.com/img/images/timestamp.width-800.jpg OpenTimestamps OpenTimestamps combines the magic of Merkle Trees with the immutability of Bitcoin’s blockchain. To showcase it, Todd took 750,000,000 hashes of files from the Internet Archive last week to combine them all into one Merkle Tree. The “root” of that tree, then, was placed into a Bitcoin transaction. He sent that transaction over the Bitcoin network to have it included in the Bitcoin blockchain. This is now a couple of weeks ago and virtually impossible to ever revert. As a result, almost the entire Internet Archive is now hashed into Bitcoin’s blockchain. Anyone can take any document from the Internet Archive and verify that it existed in its current form four weeks ago. If the hash checks out, the document has not been altered since, nor could it have been created later. Finally, to make this timestamp actually useful, the OpenTimestamps team — specifically Riccardo Casatta, Luca Vaccaro and Igor Barinov — created an accessible search interface and an in-browser timestamp verifier. With it, anyone can easily browse through the Internet Archive’s database and immediately see whether the records check out with the corresponding hash, as embedded in Bitcoin’s blockchain. For the first time in history, historical archived data cannot be altered without being noticed.
