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

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.

Adam back: blockstream ‘has no patents related to segwit’

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.

AML: US Rules Would Force Declaration Of Crypto At Borders

An update to US anti-money laundering (AML) legislation currently going through Congress would oblige travelers to declare digital currency at the border.


AML Rules Target $10k+ Crypto Holdings

S. 1241, a new bill sponsored by Senator Chuck Grassley, proposes adding the terms ‘digital currency’ and ‘prepaid access devices’ to existing list of financial items subject so such AML procedures.

It would also include reference to “any digital exchanger or tumbler of digital currency.”

Ostensibly designed to prevent trafficking of funds over $10,000 in value, the resulting powers given to border authorities could be nonetheless considerably more sweeping than at present.

United States Congress

While it is unclear how those arriving in the US would be screened for digital currency holdings, the Bill makes provision for a report to be commissioned ironing out the finer points.

The text states:

Not later than 18 months after the date of enactment of this Act, the Secretary of Homeland Security, in consultation with the Commissioner of U.S. Customs and Border Protection, shall submit to Congress a report—

(1) detailing a strategy to interdict and detect prepaid access devices, digital currencies, or other similar instruments, at border crossings and other ports of entry for the United States; and

(2) that includes an assessment of infrastructure needed to carry out the strategy detailed in paragraph […]

Coin Center ‘Reaching Out’ For Debate

The bitcoin community is already reacting with caution to the legislation as it stands, with multiple questions being raised as to how lawmakers could enforce it in practice.

“We’re reaching out to the relevant offices,” Coin Center CEO Jerry Brito said in a Twitter response.

EU Focuses On Dark Web, ID Linking

The move is reminiscent of similar plans across the pond in the European Union regarding declaration of digital currency funds, this time at the point of spend.

While border controls are not currently on the table, legislators are keen to enforce similar AML controls on anyone holding any form of virtual funds.

Formally revealed in March, users could soon face obligatory linking of their personal identity to their wallet.

AML could force linking users' ID to their digital wallets

More recently, a joint “consortium” by the European Commission, INTERPOL and others will research ways in which illicit use of the dark web can be curbed. Participants promise that:

“The consortium will analyze legal and ethical requirements and define guidelines for storing and processing data, information, and knowledge involved in criminal investigations without compromising citizen privacy,” participants promise.
