Amazon Web Services Launch Free Ethereum and Blockchain Hyperledger Templates for Users

  • Amazon is the third-largest retailer in the world.
  • The world's largest retailer, Walmart, has filed patents for multiple blockchain networks and interfaces.

Blockchain adoption is surging worldwide as corporate giants fall in line and take measures to adopt and integrate the distributed ledger technology to handle various aspects of their business. 

Walmart, the largest retailer in the world has been filing blockchain patents, Samsung may be about to use blockchain for their huge logistics operations, and now Amazon Web Services (AWS) has deployed Ethereum and hyperledger fabric blockchain templates on its website. According to Amazon's subsidiary AWS, the templates have been created to allow for quick and easy deployment of blockchain systems on site. 

A fast and easy way to create and deploy secure blockchain networks using open source frameworks

The templates are there for users to integrate blockchain into their Amazon retail enterprises, perhaps the highest level of mainstream blockchain customization and adoption to date in the blockchain space. Amazon generated $30 billion worth of revenue last year and, allowing sellers to develop their own blockchain systems independently of each other, could allow for rapid development and practical implementation of different experimental blockchain networks. 

There is no additional charge for AWS Blockchain Templates. You pay only for the AWS resources needed to run your blockchain network. You can create and deploy blockchain networks in any public AWS region.

The tools to create new blockchain networks can be found on the getting started page of AWS. The launch of the templates comes two years after AWS partnered with Digital Currency Group (DCG) in 2016 to begin experimenting with and integrating blockchain. 

'Bitcoin Type' Privacy Enhancing UTXO Transactions Now Available on EOS

Omar Faridi

The developers of pEOS, a project focused on enabling private and “untraceable” transactions on EOS, one of the largest platforms for building decentralized applications (dApps), have noted that they intend to provide tools which will allow users to conduct efficient token transfer transactions while maintaining their financial privacy.

“Accelerating Any Aspect of EOS” in Direction of Providing Greater Privacy

As explained in pEOS team’s Medium blog post, published on May 16, 2019, the privacy-enhancing crypto project is "much larger than just delivering pEOS.” The development team wrote:

We consider part of our mission to help educate, provide support, provide tools, and accelerate any aspect of the EOS blockchain in the direction of providing privacy enabled features and technologies. We strongly believe in the multiplicative effect this can have to every aspect of the EOS ecosystem.

Bitcoin Type UTXOs for EOS

In order to add more functionality to the EOS blockchain, while promoting economic privacy, the developers of pEOS have introduced a new smart contract which “implements bitcoin type” unspent transaction outputs (UTXOs) for EOS-based tokens.

As mentioned in pEOS team’s blog, UTXO was first used by the developers of the Bitcoin protocol, and it is “one type of output which can be either unspent (UTXO) or spent.” The outstanding balance of a UTXO-enabled wallet can be calculated by adding up all its spendable UTXOs, pEOS’ blog noted.

A UTXO Needs to Be Spent “as a Whole”

Transactions are processed by spending a certain number of UTXOs while producing new UTXOs for the recipient (of a transfer) and for any change that is returned to the sender, pEOS’ blog explained. The pEOS team clarified that “amounts in UTXOs don’t mutate.” This means users cannot “spend only some part of a UTXO.” In order to conduct such transactions, users must spend the UTXO “as a whole.”

According to pEOS’ team, these “constraints on what a UTXO is and how it is immutable, is what allows for privacy algorithms to be built on top of them.” For instance, the privacy-centric CoinJoin algorithm can be used with the smart contract-based UTXO code released for EOS, pEOS’ developers revealed.

On May 17, 2019, Block.one, the Cayman Islands-registered developer of EOS, released new software development kits (SDKs) for both Swift and Java developers. The latest SDKs for EOS aim to provide more support for native smartphone applications in order to offer “richer, more engaging experiences.”
