Bid to Connect Ethereum and Zcash Blockchains Reaches New Milestone

Work on integrating Zcash’s privacy-focused tech with ethereum’s distributed applications platform has reached a new milestone. According to a blog post by Ethereum Foundation team lead Christian Reitwiessner and Zcash Company engineer Ariel Gabizon, new code has been tested as part of effort to create a means to verify zk-SNARK proofs written in Solidity, ethereum’s smart contract language. Zk-SNARKS are zero-knowledge proofs that provide a means to shield certain types of data (like who is sending what amount of digital currency), and form a central component of Zcash. As Reitwiessner and Gabizon wrote: “We tested the new code by successfully verifying a real privacy-preserving Zcash transaction on a testnet of the ethereum blockchain. The...

Where's Casper? Inside Ethereum's Race to Reinvent its Blockchain

Where's Casper? Inside Ethereum's Race to Reinvent its Blockchain

If you’ve been following ethereum at all, you’re likely aware the blockchain project has a lot riding on something called ‘proof of stake’. A radical change to how the network forms consensus, the idea is somewhat simple in aim, but potentially history-changing in scope. The story goes like this: As far back as 2011, some developers began to worry about the energy that bitcoin – which uses a process called ‘proof of work’ (PoW) – would require at scale (some recently estimated that it would consume as much energy as Denmark). Further, bitcoin’s mining firms were already becoming big businesses, and there was fear that this change would negatively impact user growth. Sure, there is the argument that proof-of-work’s...

Ethereum Classic Freezes 'Difficulty Bomb' With 'Diehard' Fork

Ethereum classic just forked again. Though hard forking can be a particularly contentious way of upgrading open blockchains (particularly since it can split the network if not all miners decide to update), the developers behind the project are calling the effort a success thus far. Ethereum classic developer Arvicco noted on social media that the mining hashrate is stable on the network and transactions are being transmitted normally. Named “Diehard” after the 1980s action film, the fork packages together a few changes, including a tweak to address denial-of-service attacks that slowed down ethereum classic and its sister blockchain, ethereum, last fall. Yet it’s one of the other upgrades included in the release that could further...

Blockchain Angels Invest $1 Million in Bitcoin-Ethereum Hybrid Qtum

Blockchain Angels Invest $1 Million in Bitcoin-Ethereum Hybrid Qtum

A new public blockchain that would seek to merge popular design aspects of both the bitcoin and ethereum blockchains has raised $1m in funding. By marrying bitcoin’s transaction model with a similar consensus system to the one in development at ethereum, Singapore-based Qtum is seeking to appeal to distributed application developers who may be experiencing difficulties with one or both systems. Investors in the company include a host of notable blockchain entrepreneurs, including ethereum founder Anthony Di Iorio, OKCoin CEO Star Xu, BitFund founder Xiaolai Li and Fenbushi partner Bo Shen. Speaking to CoinDesk, Di Iorio lauded the team’s leadership as one of its main strengths. “All in all, I believe them to be the best team out of China and...

Status, an Ethereum Light Client, Unveils its Feature Light Alpha

Status.im, an Ethereum light client targeting Android & iOS, launched its feature light alpha today. It is aimed at early adopters and developers. With alpha release, Status aims to provide developers with a glimpse at how interacting with decentralized applications (DApps) will look through its open source interface. Status is more than just an Ethereum Wallet. It is a messenger, DApp browser, and an open source project with the mission to facilitate the transition to a more open internet and financial system through the new paradigm Ethereum represents. Status enables its users to access decentralized applications, along with sending encrypted messages, smart contracts, and digital currency to one another using Ethereum’s decentralized protocols. Hoping to...
