New IC-­STAMP content integrity service is free for moderate usage Integrity Chain today announced the launch of its IC­-STAMP service, a leading-edge application of blockchain technology for the general public. The free service delivers public proof for the time and contents of private files by embedding their unique cryptographic fingerprint in the blockchain. By using only a browser and email, users no longer face the barriers of specialized knowledge, complex tools or obscure cryptocurrencies. Tampering with the past is now history. “Blockchain technology has enormous potential as a public ledger, partly by providing an unalterable ‘arrow of time’ which we utilize to establish integrity,” said Eric Schorn, Co-­Founder of Integrity Chain. “However, broad adoption is severely limited by the large amount of complexity involved. Our vision is that of simplification and thus usability for a mainstream audience.” “Services like IC­-STAMP that leverage blockchain approaches offer several advantages -­ cost, simplicity and flexibility among them -­ compared to legacy and proprietary offerings for content security and integrity. Their adoption is set to accelerate,” commented Peter Harris, Principal at Lighthouse Partners, a consulting firm that focuses on business applications of blockchain and other disruptive technologies. Integrity Chain’s IC-­STAMP service can be used …

Antony Lewis is a bitcoin and blockchain consultant and blogger, who previously served as the director of business development at bitcoin exchange itBit.  In this article, Lewis attempts to break down some of the more misunderstood questions circulating among institutions seeking to adapt distributed blockchain tech for alternative uses. There are good reasons and bad reasons to use blockchains. In conversations with people considering blockchain use cases, I have noticed common confusions arising from certain words. At issue, is that they were initially used in a narrow context (usually to describe bitcoin’s blockchain), and are now being interpreted more generically for other blockchains, in cases where they may no longer apply. In this post, I hope to untangle some of these common misconceptions. Theme: Blockchains are secure Writing data Bitcoin has specific security features for writing data due to the burden of proof-of-work consensus. That is, in order to add blocks of transactions to the blockchain, you have to validate all the transactions within the block (easy) and then perform repeated calculations (called hashing) to find a magic number that makes your block valid and acceptable to the other participants according to the rules of the network (easy, but computationally expensive, therefore …
