Worldwide popular e-commerce giant Amazon hits the blockchain news today for winning two patents related to digital signatures integrity protection and distributed data storage improvement. Both of the patents were published today, November 13 by the US Patent and Trademark Office.
The first patent application was filed in April 2018 where a signature delegation method was outlined, for ‘’protecting the integrity of digital signatures and encrypted communications’’. This method will allow the distribution and validation of cryptographic keys that can be used only once.
The encrypted keys are formed as a ‘’Merkle Tree’’ structure that represents a binary system of hashes built from the bottom up. Merkle Trees are a key element of blockchain systems since they allow huge amounts of data to be securely verified.
As crypto media platform Hackernoon explained:
“The Merkle Root summarizes all of the data in the related transactions and is stored in the block header. It maintains the integrity of the data. If a single detail in any of the transactions or the order of the transaction’s changes, so does the Merkle Root. Using a Merkle tree allows for a quick and simple test of whether a specific transaction is included in the set or not.”
Amazon proposed the same Merkle Tree structure aiming to solve how to delegate signing authority from a central entity to multiple subordinates that will be authorized. The second patent that was first filed in December 2015, aims to solve issues related to distributed data storage.
The patents suggest that these methods can help reduce storage redundancy but still allowing maximum availability. Amazon also filed for other crypto-specified inventions but we will find out more about them in the near future.
Telecom Giant AT&T Interested In A Blockchain-Based Social Media ‘Mapping’ System
“The social media history map platforms described herein may take advantage of the immutable and permanent nature of blockchain records to store, and provide access to, data representing online transactions that occur on multiple social media applications.”According to the filing, content creators would keep the ownership of their data on the "mapping" platform:
“However, instead of passing ownership of blocks or data between users, a social media account owner maintains primary ownership of his or her online transaction data. What passes from the social media account owner to other users of the social media history map service, such as followers of the social media account owner, is a notion of elevated visibility rights.”This is just one more patent application in the series that were submitted by companies such as Xerox, American Express, IBM and others - and a new milestone for AT&T overlooking its expansion in the field of blockchain.

TRON’s DApp Usage Jumps 48% To +1 Million Transactions Last Week
“This week, the 24-hour transaction number for Dapps reached 1.04M, a 48% increase compared with last week; the 24-hour trading volume hit 640M TRX, an 151% increase compared with last week. We have seen significant increases in both indexes […]”One of the most interesting projects built on Tron is Seedit which is a decentralized platform that lets users contribute funds to the content creators that they most appreciate. Project Atlas is also a well-known project which incentivizes people to seed content on the BitTorrent protocol, which was acquired by Tron back in July this year.
LinkedIn’s Largest Growing Job Sector Is Blockchain Development
“It’s no surprise that we’re seeing an explosion of machine learning roles and continuing growth of data science roles. In fact, we started to see glimmers of this in last year’s report; however, both fields are starting to see more specialized roles emerge. It also may not shock you that Blockchain Developer is topping the list following this year’s surge in interest around blockchain and cryptocurrency.”The great news for all of the people interested in a career in this sector is that there are plenty of universities now that adopt blockchain-related courses which help to boost the blockchain expertise in the following years.
