Circle Is Building a Master Mobile Payments Network on Ethereum

Blockchain startup Circle has unveiled new software aimed at connecting the world's digital wallets.
Known as 'CENTRE', the project seeks to create a way for digital wallets (like Venmo, Alipay or the startup's own Circle Pay) to communicate with one another. Put more simply, CENTRE as envisioned would let the companies behind those apps to transmit and settle funds between them.
At its heart, the project targets the so-called "walled garden" issue, wherein different platforms – whether they be a social media site like Facebook or a payments app like Venmo – exist largely within their own ecosystems. Circle is aiming to build a bridge between them, betting that it would make for a more inclusive consumer payments environment.
Circle released today a new white paper outlining the specifications and intended use for CENTRE, which notes that the project has grown since being established as an internal method for transacting in both cryptocurrencies and fiat currencies in digital form. Notably, the startup is planning to develop a new implementation of CENTRE on top of the ethereum network, complete with its own ERC-20 token, the CENT.
CENTRE makes further use of the token standard, however, as node operators – whether they be an app operator, a bank or another financial institution – could issue their own ERC-20 tokens tied to a particular fiat currency to send between other parties on the CENTRE network.
Transactions between nodes would be settled through smart contracts, or self-executing pieces of code that trigger when certain conditions are met. That the startup would move in this direction is perhaps unsurprising – last December, Circle revealed its work on "Spark", a smart contract platform it uses to settle transactions.
CENT, according to the paper, is meant to act as a common medium of exchange between apps that originally use entirely incompatible currencies. This means that while nodes aren't required to accept, say, a USD-tied token issued on ethereum by another party on the CENTRE network, they do, by default, have to accept the CENT.
The startup explains:
"The CENTRE Token, in addition to its other uses (such as accessing the service provider protocol), provides a way for wallets which have no fiat tokens in common to transact, as they will be able to use CENTRE Tokens to obtain the needed fiat token in common to transact."
Circle is planning to create a CENTRE Foundation to spearhead development of the initiative, and the establishment of that nonprofit group is expected to happen in the coming months.
Though it's unclear who will make the shift, the startup said that "several key Circle employees" are expected to form the foundation's early leadership team.

How Blockchain Could Help Tech Giant Cisco Reboot

Cisco is changing. The technology firm best known as the supplier of enterprise computer hardware has seen a slow, steady decline in revenue from some of its core products. As a result of an increasing number technological services being virtualized, and the storage of information moving to the cloud, the $158bn firm has been  restructuring  and exploring new ways to capitalize on connected devices. But amidst this change in identity, it's in identity itself where some of the California-based company's most interesting new experiments are taking place. With a series of early stage blockchain  projects , Cisco is now pushing even deeper into what could end up being much more than a way for employees to prove who they are across subsidiaries. In conversation with CoinDesk, Robert Greenfield IV, Cisco software engineer and executive team lead of the firm's Connected Black Professionals resource group, explained how several blockchain projects have evolv...

Bitcoin in Africa: Insights from the Continent’s Biggest Bitcoin Exchange

Isn’t it absurd that nearly 326 million people representing 80% of the adult population in Africa do not have access to bank accounts? This wretched situation denies countless of people financial freedom in the so-called dark continent. Bureaucratic tenors and economic exclusion inter alia have paved the way for the current phenomenon. Last year a study of 10 African nations with unusual inflationary ratio had South Sudan registering an unimaginable inflation rate of 295 percent. Egypt had the slightest with 12.30 percent. African governments continue to plunder the riches of the African people through Inflation. This makes it considerably insurmountable for individuals to conserve their resources. Moreover, public sector borrowing has crowded out the efficient private sector that can put credit to good use. The IMF estimates that averagely credit to the private sector is estimated at 30 percent of GDP in Sub-Sahara Africa. CCN spoke to Werner van Rooyen, Head of Business Develo...
