  1. None
  2. • Cardano (Ada) Rust project • 'Liquid Network': Blockstream's Bitcoin

    Sidechain goes Live • Ethereum Constantinople Upgrade Delayed Until 2019 • Security issues found in ½ of all exchanges • Zcash- Sapling • Bitcoin Smart Contracts • EOS Report dev news
  3. Cardano • Cardano launched an open source project, toolkit that

    will allow third party developers penetrate the Cardano ecosystem. • Rust project is a Cardano API that was written with a command-line interface and a Cardano wallet and works with the Cardano settlement layer that is designed in Haskell. • It is compatible with iOS, web and Android
  4. Bitcoin Sidechain • Liquid and Lightning: What’s the Difference? •

    Liquid is sidechain built on the Bitcoin network, facilitating faster bitcoin transactions between businesses and individuals. • The main purpose for the technology is faster settlements, improved transaction confidentiality, and tokenization for various assets.
  5. Ethereum Hard Fork • Constantinople Test Hard Fork Goes Awry

    • Notable changes include a 33% reduction in Ether block rewards and a potential change to the consensus mechanism of Ethereum to rid the network of ASICs
  6. Exchange Security • only 46% of cryptocurrency exchanges meet the

    desired security parameters • Console errors - 32% of exchanges have code errors that lead to operational malfunction • User Account Security - 41% allow for the creation of a password less than 8 characters • Web Protocols Only 10% of exchanges used all 5 security measures - HTTPS headers in URLs, X-SXX- protection headers, content security policy headers, x-frame-options headers, and x-content-type headers.
  7. Zcash Saplin • Light client support • The Sapling protocol

    will allow shielded transfers to be completed with about 100 times less memory (40mb of memory) and probably six or more times faster. • with the upgrade, the team hopes it can ultimately remove transparent transactions that can be damaging anonymity when used together with shielded transactions. • an era of "privacy-by-default"
  8. Smarter Bitcoin • First Truckload Shipment Using Bitcoin Smart Contracts

    using Rootstock (RSK) • Funds for the transaction were held in escrow by the smart contract on the integrated RSK platform and were automatically released to the carrier upon delivery.
  9. EOS Report • “EOS is not a blockchain, rather a

    distributed homogeneous database management system, a clear distinction in that their transactions are not cryptographically validated.” • “The performance metrics observed when factors such as real world network latency and packet loss are implemented indicate that TPS in EOS approaches levels comparable to Ethereum.” • Various forms of consensus failure were shown in the network testing. Consensus is entirely dependent upon the voting mechanism which is based on social consensus, not algorithmic BFT consensus.”
