The architecture for sharing tokens across blockchains promises traction

After lightning fundraising round, Cosmos puts Ethereum high on dev roadmap

In April, the Cosmos project raised about $17m in half an hour on the promise to someday let users freely share tokens among Bitcoin, Ethereum and other popular blockchain protocols.

On Friday at the Global Blockchain Summit in Shanghai, China, the Switzerland-based nonprofit behind it committed that Ethereum support is high on its development roadmap.

One of the problems with blockchain platforms is that there are so many – from JP Morgan's finance-focused Quorum to The Linux Foundation's Hyperledger Fabric. As the wars for dominance are still young, it's not clear yet how many players will stick around, Jacob Eberhardt, a computer science PhD student at Technical University of Berlin in Germany studying Blockchain, told The Register.

Some developers are trying to find ways to join separate blockchain pieces so you'd be able to flow relatively freely from one to the other. Polkadot, for example, wants to allow smart contracts – privacy-preserving digital contracts directly between parties that execute based on the terms – to interact with each other for tasks such as sharing computations.

Cosmos is like a special, laser-focused version of Polkadot for specifically sharing assets between blockchains. The idea is that there would be a central hub that manages the transfer of tokens between two different protocols, such as Bitcoin and Ethereum.

In the new announcement, Cosmos's parent, Interchain Foundation, committed that connecting to Ethereum chains is "high priority" on its roadmap. Further, it will create a special cryptocurrency token that can copy the account balances of Ethereum holders and move them into the Cosmos chain, where they can be redeemed (the other tokens the architecture will use for "staking" are promised not to conflict with Ethereum).

"It's a strategically good move," Eberhardt said, because most blockchain prototypes are with Ethereum and it's probably the most public of all the alternatives. Although "significance is hard to judge from a technical standpoint as of now, since there is little detail provided."

Gavin Wood, an Ethereum co-founder who proposed Polkadot and is collaborating with the Cosmos team to make sure the two networks can work together, told The Register, "I guess this is meant to be evidence of their commitment to make [Bitcoin and Ethereum chain connection] happen."

However, "there's quite a bit of optimism which perhaps doesn't quite reflect the magnitude of the task at hand," he said. "When I see a deployed, functional public testnet that has solid security guarantees, then I'll be impressed."

According to Cosmos, its mainnet is slated to go live in December. ®

    “It is ordered that the election that commenced on February 8 is set aside, and a new election shall be conducted,” Lisa Henderson, regional director at the National Labor Relations Board, ruled [PDF] on Tuesday.

    The Nordic country's National Cyber Security Center (NCSC-FI) lately warned that scam messages written in Finnish are being sent in the hope that recipients will click the included link to a website that requests permission to install an application that's malicious.

    "The messages are written in Finnish," the NCSC-FI explained. "They are written without Scandinavian letters (å, ä and ö) and include, for example, the characters +, /, &, % and @ in illogical places in the text to make it more difficult for telecommunications operators to filter the messages. The theme of the text may be that the recipient has received a voicemail message or a message from their mobile operator."

  • AsmREPL: Wing your way through x86-64 assembly language

    Assemblers unite

    Ruby developer and internet japester Aaron Patterson has published a REPL for 64-bit x86 assembly language, enabling interactive coding in the lowest-level language of all.

    REPL stands for "read-evaluate-print loop", and REPLs were first seen in Lisp development environments such as Lisp Machines. They allow incremental development: programmers can write code on the fly, entering expressions or blocks of code, having them evaluated – executed – immediately, and the results printed out. This was viable because of the way Lisp blurred the lines between interpreted and compiled languages; these days, they're a standard feature of most scripting languages.

    Patterson has previously offered ground-breaking developer productivity enhancements such as an analogue terminal bell and performance-enhancing firmware for the Stack Overflow keyboard. This only has Ctrl, C, and V keys for extra-easy copy-pasting, but Patterson's firmware removes the tedious need to hold control.
