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.

Adam Back to Jihan Wu: SegWit Not ‘Complicated,’ Fixes Satoshi’s Bug

· March 31, 2017 · 8:00 am

Hashcash inventor Adam Back has said Segregated Witness (SegWit) “fixes” an original bug in Bitcoin from creator Satoshi Nakamoto.


Back: SegWit ‘Fixes Satoshi Bug’

As part of a Twitter exchange Friday, Back rebuffed criticism from Bitcoin Unlimited proponent Jihan Wu, demonstrating how SegWit is beneficial to the virtual currency’s core protocol.

Wu, who is a co-founder of mining conglomerate Bitmain, had said that the technology would make the network “more complicated.”

“SegWit is not more complicated,” Back wrote.

“It fixes Satoshi’s bug that txid=H(tx,sig) to txid=H(tx) this is not complicated, and it is necessary to fix.”

What’s more, if implemented, SegWit can can actually help reduce the so-called “technical debt” burden of complicated code albeit having its own tradeoffs, which are assessed here.

The segwit code has been heavily reviewed, which helps resist the introduction of technical debt at both a code and design level…Segwit has multiple independent reimplementations, which helps discover any unnecessary complexity and technical debt at the point that it can still be avoided.

SegWit: Complicated & Straightforward

Wu’s stance echoes a broader opinion from the Chinese community in particular that SegWit creates unnecessary complexity within Bitcoin.

In an interview with Bitcoinist this month, for example, Leon Liu, CEO of P2P trading service Bitkan, said that this was a reason why the technology “is not the best solution for Bitcoin scaling.”

“Segwit will not be the best solution for Bitcoin scaling, it will make the Bitcoin network more complicated,” he stated.

At the same time, efforts have been made to allay such fears, Blocktrail CTO Ruben De Vries commenting last year that SegWit “is not very complicated if you already know the ins and outs of the Bitcoin protocol.”

Back meanwhile has praised attempts at educating the wider community on the nature of scaling solutions without resorting to ‘political’ siding.

An explainer on SegWit by Andreas Antonopoulos garnered considerable praise, Back describing it as “the best he’d seen on the topic.”

On its benefits, Antonopoulos wrote in the blog post, which originally came out in August last year:

“Firstly, segregated witness reduces the overall cost of transactions by discounting witness data and increasing the capacity of the bitcoin blockchain.

“Secondly, segregated witness’ discount on witness data corrects a misalignment of incentives that may have inadvertently created more bloat in the UTXO set.”

Litecoin Bounce on SegWit Rumors?

SegWit is traditionally considered ‘complicated’ compared to merely increasing the Bitcoin block size, despite the latter requiring a hard fork of the virtual currency.

Currently, the proposal is still behind Bitcoin Unlimited though both need at least 95% to activate.

Outside the Bitcoin debate, rumors surfacing that Litecoin is to activate SegWit may have led to a surprise expansion in value of the altcoin by around 30%.

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.

What are your thoughts on the announcement by F2Pool? Is it such a big deal as they claim it is? Let us know in the comments below!
