TxTenna is Coming: Send Bitcoin Without the Internet Thanks to goTenna and Samourai

Published

on

TxTenna looks to combine mesh network with bitcoin transactions, allowing for users to transact offline.  A partnership between Samourai Wallet and goTenna makes this possible. Samourai Wallet is an Android application that when used with goTenna’s antennas, will allow users to send transactions to their recipients.

The Last Push for Decentralization

Mesh networks are a concept where users connect directly with each other. This aligns with the philosophy of Bitcoin and cryptocurrency of using a P2P infrastructure.

goTenna’s offerings are also affordable, making mesh networks a practical alternative to traditional networks. Less than 25 nodes are needed for a well-connected network in a three-by-three-mile area; similar technologies would need hundreds of nodes to achieve similar results.

Most transactions today require a connection from either an ISP or cellular tower, a centralized choke point in an otherwise decentralized system.

This raises concerns in case of a cybersecurity attack, or periods of downtime if a natural disaster were to destroy infrastructure. goTenna’s Decentralized Applications Engineer Rich Myers told Bitcoin Magazine:

“Mesh networks are the only legitimate alternative to these traditional centralized communication networks. They are completely decentralized and democratized, leaving the power of communication in the hands of the people. Beyond that, they are much more resilient to unforeseen disasters — the only thing these networks need to function is a mesh networking device paired with a smartphone.”

How Does TxTenna Work?

In terms of what this means for bitcoin users, txTenna will enable transactions to be sent and received with virtually 100 percent uptime. Once a transaction is signed in the mobile wallet, the offline transaction is passed to the TxTenna app and broadcast to nearby mesh nodes with a paired goTenna mesh device. The transaction is relayed by goTenna devices in the area until an internet-connected node receives it and forwards to the Bitcoin network.

After discussions with Samourai, the goTenna team’s suggestion was taken on board, as In the Mesh wrote on May 14:

“We suggested using the free goTenna SDK to build an app for broadcasting offline bitcoin transactions via goTenna Mesh devices. Today we are pleased to announce that the Samourai team took our suggestion, and went well beyond our expectations! The result is the TxTenna app.”

With no reliance on a third party, there is no risk of downtime or security. Samourai has always been a privacy-conscious wallet with features like PayNyms and Ricochet, features that increase fungibility and security.

There is no specific release date, but progress on the project will be announced later in 2018. While it’s not the first to look into alternative ways to access the blockchain, it is the most viable. The software and hardware required already exists, and all that’s needed is a bridge between the two to make it a reality. Along with initiatives such as Blockstream’s satellite, TxTenna will aid individuals in developing economies where bitcoin adoption may have been lagging due to inadequate infrastructure.

Australians Can Pay Utility Bills With Bitcoin (BTC)

Published

on

Bitcoin (BTC)–In terms of adoption for cryptocurrency, being able to pay for real world goods and services with the digital currency has long been viewed as the gold standard. The bear market of 2018 has led to a shift in focus away from the fundamentals of crypto and the usability of blockchain transactions in favor of wild price speculation. However, an Australian-based partnership is attempting to provide a solution for customers looking to pay their utility bills with cryptocurrency.

Cryptocurrency exchange Cointree announced a joint-venture with billing platform Gobbill to give Australian customers the opportunity to pay their utility bills with cryptocurrency. The goal of the union is to provide a solution for automated billing via crypto, with Gobbill functioning as the intermediary in the exchange, taking user funds in crypto and making the payment in fiat.

Using the Cointree wallet, users of the cryptocurrency exchange will be able to convert stored coins automatically into utility bill payments, giving customers the opportunity to pay in BTC, XRP, and nearly 40 other currencies. While Australian utility companies will not be accepting crypto directly for payment (the exchange involves a conversion to fiat), it does represent a way for Australian crypto users to get around having to cash out of their denomination on exchanges to free up funds for utility payment. The service is being aimed at small businesses and average investors, with the co-founder and CEO of Gobbill, Shendon Ewans, expounding upon the planned form of payment,

“We anticipate a surge in the number of customers who would like to pay their bills in crypto in the coming years. Our partnership with Cointree will cater to this market and ensure Gobbill continues to remain ahead of the curve when it comes to allowing our users to pay their bills automatically, while knowing they’re protected from fraud and scams.”

According to Ewans, Gobbill views this partnership with Cointree as getting ahead of the curve, a refrain we have heard several times from tangential businesses attempting to capitalize on cryptocurrency. By offering a service that automatically takes payments in cryptocurrency, Gobbill is exposing itself to the growing, and vocal, userbase of cryptocurrency, in addition to paving a future for their company that involves a takeoff in the digital currencies.

Cointree also sees partnerships for bill payments and automatic drafting as a way to increase their customer base, with efforts already enacted for several years on the front of crypto-to-bill payment. Jess Rendon, operations manager of Cointree, reported that the company has processed $100 million in bills paid in 2017,

“Last year alone we had about AU$100 million of bills paid and saw ten times growth in this payment feature.

CCN reports that paying bills with cryptocurrency has seen an explosion in Australia over the last several years, having grown by 3300% in a three-year period. While the system devised by Gobbill is still a step removed from utility companies accepting Bitcoin and altcoins directly, it does provide another avenue for investors looking to use their coins outside of exchange speculation.

Bakkt CEO: ‘With Our Solution, the Buying and Selling of Bitcoin Is Fully Collateralized or Pre-Funded’

Published

on

On Monday (20 August 2018), Bakkt, the new company announced by Intercontinental Exchange (ICE) on 3 August 2018, declared that with its solution, “the buying and selling of bitcoin is fully collateralized or pre-funded.”

ICE’s press release mentioned that Bakkt would be offering a one-day phsyically-delivered Bitcoin futures product:

“As an initial component of the Bakkt offering, Intercontinental Exchange’s U.S.-based futures exchange and clearing house plan to launch a 1-day physically delivered Bitcoin contract along with physical warehousing in November 2018, subject to CFTC review and approval. These regulated venues will establish new protocols for managing the specific security and settlement requirements of digital currencies.”

This is how Bakkt announced today’s news on Twitter:

Kelly Loeffler, the CEO of Bakkt, provided more details in a post on Bakkt’s Medium blog.

Loeffler started by saying that to achieve a “trusted infrastructure for trading, storing and spending digital currencies”, Bakkt would need to provide:

  • “a consistent regulatory construct”;
  • “transparent, efficient price discovery”; and
  • “an institutional quality pre- and post-trade infrastructure”

She then moved to the “meat” of Bakkt’s announcement:

“A critical element to price discovery is physical delivery. Specifically, with our solution, the buying and selling of Bitcoin is fully collateralized or pre-funded. As such, our new daily Bitcoin contract will not be traded on margin, use leverage, or serve to create a paper claim on a real asset.”

She noted that this provided support for market integrity and differentiated them from other exchanges which “allow for margin, leverage and cash settlement.” She went on to say that once you take into account the fact that Bakkt also provides “a secure, regulated warehouse solution”, it was easy to see how this infrastructure could “help more institutions and consumers participate in the asset class.”

For many crypto traders/investors and analysts, what Bakkt announced today sounded great. However, not everyone was equally excited.

Caitlin Long, 22-year Wall Street veteran (including over eight years at U.S. investment bank Morgan Stanley) who has been active in Bitcoin since 2012, expressed her concern about “financialization” (i.e. when an asset class becomes investable by large institutional investors) of cryptocurrencies, and especially her worries about “leverage-based financialization” (which arises “either from the issuance of more assets out of thin air to dilute existing holders, or from the creation of more claims to the asset than there are assets”) in an article for Forbes published on 31 July 2018.

Upon hearing Bakkt’s announcement earlier today, she sent out the following tweets to explain that although the confirmation that Bakkt’s daily Bitcoin contract would not be traded on margin, use leverage, or serve to create a paper claim on a real asset” was a good thing, she still had a few reservations:

Biometric Cryptocurrency Card Protects Bitcoin with Fingerprints

Published

on

Unikeys has officially announced its UKey cryptocurrency card.

In form, it’s shaped like any other regular payment card. But it’s designed to host multiple popular cryptocurrencies including Bitcoin, Bitcoin Cash, Ether, and Litecoin. What’s more, it features an embedded fingerprint sensor. Once a user’s fingerprint data has been registered and stored in the card’s Secure Element, the card is then able to biometrically authenticate the user for each transaction, ensuring a high level of security.

The biometric component is the product of a collaboration between Unikeys and Hong Kong-based MeReal Biometrics, which obtained its fingerprint sensor technology from Sweden’s Fingerprint Cards. Fingerprint Cards has been very busy in recent months seeking to secure a leading position in the biometric cards market as major financial services brands like Visa and Mastercard prepare for mass commercialization of this kind of technology; Unikeys, for its part, is ahead of the curve.

Of course, a key to success for the latter company will be establishing merchant support for its card’s cryptocurrency payments, and as RFID Journal reports, Unikeys is currently in talks with “several companies” concerning this issue. Unikeys’ CEO says the company is also planning to launch a pilot for its solution in Hong Kong, though details about the project are forthcoming.
