Blockstream’s New Green Wallet Is ‘Probably the Most Secure’ On the Market

Bitcoin HODLers rejoice. Now there’s an even safer, easier way to store your private keys–the all-new Blockstream Green Wallet for iOS and Android.


Blockstream Releases Green Wallet

Rebranded from the GreenAddress Bitcoin mobile wallet, this all-new version promises to offer a more seamless UX and heightened security. It’s arguably one of the safest, sleekest, and most convenient mobile wallets for storing and tracking Bitcoin transactions.

Like its predecessor, this wallet uses 2-of-2 multisig by default. Perhaps one of it’s most impressive features, though, is that the Blockstream Green keeps one key on your device and the other on the company’s servers.

This means that if you lose your mobile device or it gets stolen, no one can get their hands on your funds.

There’s also a host of 2FA methods available within the app from Google Authenticator to email, phone call, or SMS, depending on your preference.

According to the company post, there are “too many features” to mention. However, it reassures current users that:

We’ve retained the same multisig security that our existing users know and love, while packing in a whole host of advanced features that should get our power users excited.

Support for Trezor and Ledger

For those of you used to using the Trezor One or the Ledger Nano S, the good news is the Blockstream Green wallet works like a charm with both.

If you’ve already ordered a Ledger Nano X, you’ll have to wait a little longer until the Green is compatible. The company is currently working on support for later models.

Developed by original cypherpunk and Hashcash inventor Adam Back (one of the most respected names in the space), you don’t need to undergo KYC to use this wallet. In fact, all you need is an email address for wallet recovery purposes only.

Let’s be clear. If you’re looking to store and trade a host of altcoins, this isn’t the wallet for you. But if you’re looking for the best in cryptographic security for your Bitcoin, it doesn’t get much better than this.

According to Back:

As a cypherpunk, cryptographer, and pioneering Bitcoin miner whose technology is still used today, you couldn’t ask for a more qualified person to design your wallet security.

Back’s creation Blockstream is a pioneer in the industry with the mission of “creating the financial infrastructure of the future”–all based on the most secure blockchain there is–Bitcoin.

Bitcoin’s Liquid Sidechain Welcomes Japanese Yen Stablecoin

Blockstream has announced Crypto Garage, a joint venture with Digital Garage and Tokyo Tanshi, to serve the Japanese Bitcoin market. The partnership will soon launch the Liquid sidechain based SETTLENET suite, the first application of which will be a yen-pegged stablecoin.


SETTLENET on Bitcoin’s Liquid Sidechain

The SETTLENET suite aims to provide Japanese exchanges and OTC trading desks with enhanced liquidity, speed and security. Although why Crypto Garage feel the need to shout SETTLENET every time is anybody’s guess.

Exchanges can issue the JPY-token (L-JPY) on the Liquid sidechain, and trade it against Liquid Bitcoin (L-BTC) using atomic swaps. Atomic swaps allow instant, trustless, peer to peer trading between different types of digital asset.

Needless to say, Blockstream CEO, Adam Back’s tweet of the announcement attracted equal parts awe and mockery. The latter, in particular, from the Ripple-army, who were quick to point out how easily XRP could achieve this (though whether XRP is trustless is a different argument).

Compliant With Japanese Regulations

One of the Crypto Garage partners must have some friends in high places because SETTLENET has already received regulatory clearance. Both the Japanese Financial Services Authority and the Cabinet Secretariat approve. This leaves the JPY-token well-placed to be a key driver in Japanese Bitcoin market liquidity.

CEO of Crypto Garage, Masahito Okuma, said:

SETTLENET together with Liquid makes trustless Bitcoin trading a reality, in a sustainable regulated environment. This is going to lead to a huge boost in Bitcoin liquidity in Japan and cement the region’s place as a leader in the emerging Bitcoin industry.

Liquid Growth

The venture also marks the continuing growth of the Liquid Network sidechain since its launch last October. Blockstream market Liquid as a fast, secure, and confidential method for high trading-volume entities such as exchanges, brokers, and financial institutions to transact.

money laundering

JPY-token is just the beginning of Blockstream’s ambitions for the stablecoin market, according to CSO, Samson Mow:

We expect SETTLENET’s Japanese yen token to be the first of many stablecoin issuances on Liquid.

Blockstream Satellite Now Means Most Of The World Can Use Bitcoin Without Internet

Blockchain technology company Blockstream revealed the second phase of its satellite-based Bitcoin communications project Blockstream Satellite this week.


Satellite Coverage Expands To Asia Pacific

Part of a plan to provide free private Bitcoin sending and receiving without the need for an internet connection, the company now provides satellite coverage of the Asia Pacific region, an accompanying blog post confirmed December 17.

Phase one of the project covered North and South America, Europe, and Africa.

A major proponent of Bitcoin’s Lightning Network (LN) implementation, Blockstream also unveiled an API to allow broadcast of data via Blockchain Satellite with fees paid via the protocol.

Developers promised the API would go live for users in January 2019.

“While satellite communications are traditionally cost-prohibitive, Blockstream Satellite will finally allow developers to adopt satellite communications in their applications,” head of Blockstream Satellite Chris Cook commented in the blog post.

…Natural disaster notifications, secure personal messaging, and sending bitcoin market data to remote locations are just some of the exciting examples of the power of this service.

Battling Government Internet Control

The Satellite project originally launched in August 2017. It works via a series of Earth-based ground stations linked to the Bitcoin network transmitting blocks to a series of orbiting satellites. The satellites then rebroadcast the data to the coverage area.

At present, users running a node require only a small satellite antenna and USB receiver to keep it in sync with the network without an internet connection.

Asked about the location and “government-resistance” of the Earth-based equipment, CEO Adam Back acknowledged the trade-offs in the current status quo.

“[A]s a geopolitical neutral money Bitcoin needs to work robustly,” he wrote on Twitter.

[F]or today it depends which country, there is some diversity of ownership of the satellites. [B]ut there are 195 countries in the world, some of which have disabled internet & mobile phone service in times of turmoil.

Simplicity Language to Give Bitcoin Ethereum-Like Smart Contract Capabilities

Simplicity, a combinator-based, typed, and functional language for blockchain applications can reportedly enable Bitcoin’s Script language to handle more complex yet reliable smart contracts.


Bitcoin Script Language is Limited, For Now

According to a new research from Blockstream on Simplicity – a blockchain applications language – distributed ledgers pose a range of unique challenges, which make traditional programming languages unfit.

What’s more, Bitcoin’s Script language is limited to certain combinations of signature checks, hashlocks, and timelocks. Second layer solutions, on the other hand, such as the Lightning Network, for example, have been built on these primitives and, hence, lack the necessary expressiveness for more complicated smart contracts.

The paper also cites a recent upgrade failure of Ethereum’s EVM (Ethereum Virtual Machince), caused by a disagreement of implementations on the results of a certain computation, resulting in lost funds.

When Smart Contracts Act Stupid: Is Your ICO Smart Contract Safe & Secure?

Simplicity: Complex Bitcoin Smart Contracts

According to the research, Simplicity is capable of providing the necessary flexibility for a wide range of computations, while, at the same time, allowing users to verify the security, costs, and safety of smart contracts.

Furthermore, the low-level programing language is also purportedly capable of solving certain previously required tradeoffs between reliability and expressiveness.

As it stands now, developers are either able to build a complex yet unreliable smart contract (think The DAO) or they are able to build a basic but reliable one. Thus, Simplicity would make make it easier to write complex smart contracts that are more reliable.

It’s also worth noting that this isn’t the first project which aims to enable effective smart contracts for Bitcoin’s network.

The potential solution has already caught the attention of Bitcoin investor Trace Mayer who said the Simplicity language “can help take things to a whole new level.”

You can check out the technical detailed report on Simplicity here.

Earlier in May, Bitcoinist reported that the RSK project, which intends to build Turing-complete smart-contract capabilities for Bitcoin. RSK has partnered up with iExec in order to deliver off-chain computing and to enable dApps to access on-demand cloud computing resources.

Adam Back: Blockstream ‘Has No Patents Related To SegWit’

· May 1, 2017 · 12:00 pm

Blockstream CEO Adam Back has refuted claims by Swedish Pirate Party founder Rick Falkvinge that the company “has patents in SegWit.”


 Pirate Party’s Falkvinge: Blockstream SegWit Support Driven By Patents

In a Twitter response Monday, Back stated Blockstream “does not have any patents, patent applications, provisional patent applications, or anything similar, related to segwit.”

Falkvinge, who is a staunch supporter of bigger blocks proposed by rival scaling solution campaigners Bitcoin Unlimited, had earlier Monday released a dedicated post on his website arguing Blockstream’s SegWit support was for its own interests.

“Based on Blockstream’s behavior in the Bitcoin community, I have become absolutely certain that Segwit contains patents that Blockstream and/or their owners have planned to use offensively,” he wrote.

Falkvinge Accuses Blockstream Of ‘Goalpost Moving’

The post accuses Blockstream of “classic goalpost moving” and employing behavior that “only makes sense” under a patent battle.

Falkvinge continues:

…Based on Blockstream’s behavior, I can say with dead certainty that I’ve seen this exact behavior many times in the past, and it’s always when somebody has a dual set of reasons – one for presentation and palate and another that drives the actual course of action.

Back’s Twitter retort appears to be lifted from previous comments on Reddit left by core developer Greg Maxwell.Maxwell

“As is the case for other major protocol features, the Bitcoin developers worked carefully to not create patent complications. Segwit was a large-scale collaboration across the community, which included people who work for Blockstream among its many contributors,” he continued.

Moreover, because the public disclosure of segwit was more than a year ago, we could not apply for patents now.

Maxwell reiterated that Falkvinge had previously made similar allegations, which he had addressed separately.

“In short, Rick Falkvinge’s allegations are entirely without merit and are supported by nothing more than pure speculation which had already been debunked,” he concluded.

A Clash Of Ideals?

Falkvinge meanwhile has remained bullish on Bitcoin publicly, telling RT in February he expected Bitcoin could take over up to 10% of the foreign exchange market.

In his post, however, a clear distinction is drawn between the classic Bitcoin ethos and that of Blockstream.

The owners of Blockstream are the classic financial institutions […] that have everything to lose from cryptocurrency gaining ground,” he wrote.

The conclusion is unescapable (sic) here: Blockstream’s constant goalpost shifting has had the underlying goal to have Blockstream’s owners effectively own bitcoin through patent encumbrance.

Blockstream Welcomes New Members to Their Team, Hires On Christian Decker

Prominent Bitcoin enthusiast and proposer of ‘duplex micropayment channels,’ Christian Decker, announced on Twitter today that he will be joining the Blockstream team to work on L2 protocols.

Decker Joins Blockstream to Work on Lightning Network

According to Blockstream’s official blog, Decker was hired on to bring his expertise and talent to the company’s current research on lightning networks. While pursuing this line of work he will be joined by Blockstream developer, Rusty Russell, who has made theoretical contributions to the advancement of lightning networks in the past.

Decker is an early adopter of Bitcoin, as he began engaging in the cryptocurrency while it was still in its infancy in 2009. He has also created a number of protocols including PeerConsensus and Duplex Micropayment Channel. Furthermore, Decker brings with him the unique distinction of having authored the world’s first PhD dissertation about Bitcoin at ETH  Zurich while working with the Distributed Computing Group.

Along with Decker, Blockstream also took the chance to formally welcome other new employees that they have brought on since early this year. A noteworthy hiring has been that of Kat Walsh — joined in February as legal counsel — having served on the board of the Wikimedia Foundation for seven years, including a term as its chair. Additionally, Blockstream also hired on Eric Martindale as “Developer Evangelist.” Eric has a long history with Bitcoin, having worked a similar role for Bitpay.

Ever since the acquisition of the European-based Bitcoin wallet software provider, GreenAddress, it seems Blockstream has been trying to expand its operations. The new batch of hirings, especially that of Christian Decker, only works to further this belief as the company itself looks to continue its efforts in Bitcoin development with projects like the lightning network.

F2Pool Threatens To Withdraw Consensus Support Over Adam Back Allegations

Source: bitcoin

Bitcoinist_Roundtable Bitcoin

For those people who were under the impression the Bitcoin block size debate was over, you are sadly mistaken. That being said, things are getting interesting, as F2Pool announced they will withdraw support from the February 21 roundtable consensus unless things are sorted out on the Adam Back front. There is never a dull day in the world of Bitcoin politics; that much is certain.

Adam Back and Blockstream

Various Bitcoin community members have been claiming how Blockstream is planning to drive Bitcoin Core development in a different direction than was originally envisioned by Satoshi Nakamoto. While it is incredibly hard to verify those claims, there is something strange going on with this company, to say the least.

Based on a post made earlier by F2Pool earlier today, Blockstream President Adam Back has changed his official position title to “Individual” at the last moment when a consensus was reached regarding the block size debate on February 21st.  While it is rather strange to see such an event unfold, the bigger question is what motive has been the driving factor in this decision by Adam Back.

Looking at the Blockstream website, Adam Back is still listed as the company president. That same title and job function is listed on the official Medium post detailing what this consensus means for the Bitcoin ecosystem. However, the announcement by F2Pool seems to indicate something changed at the last moment, even though there does not seem to be any evidence to verify this statement.

F2pool feels betrayed and cheated by Adam Back’s decision to take this – allegedly – sneaky approach. So much even that they are planning to withdraw support from the roundtable consensus unless Adam back steps forward and explains this ordeal to them and the rest of the Bitcoin community.

Some Bitcoin community members are arguing it does not matter how Adam Back positions himself as a part of Blockstream, as all that matters is his support. In a way, it makes sense to list oneself as an individual rather than a company president on delicate matters like these, as it is unknown whether all Blockstream employees are on the same wavelength.

Mining Pools Don’t Need Handholding

In the end, it all comes down to who one can trust in the Bitcoin world. The answer to that question is rather simple: no one but yourself. There is no need to rely on opinions presented by others, as it is impossible to verify whether or not their intentions are honest.

This announcement marks another significant step in the scheme of Bitcoin politics that are running rampant in the digital currency ecosystem right now. All everyone should want is a workable solution everyone can agree on. All of this bickering and possible backstabbing needs to end before things get out of hand.
