Bitcoin SV Technical Standards Committee recommends first technical standard


Bitcoin Association for BSV, the Switzerland-based global industry organisation that works to advance business with the Bitcoin SV (BSV) blockchain and digital currency, today announces that the Bitcoin SV Technical Standards Committee (TSC), an industry-led standards organisation for the BSV ecosystem, , has progressed the Merkle proof standardised format to the recommended stage – the first BSV Technical Standard to reach this milestone.

Merkle proofs are vital to all uses of Simplified Payment Verification (SPV) described in the original Bitcoin whitepaper and form the foundation of most user interactions with the Bitcoin network. Because there are a wide variety of implementations transmitting and receiving Merkle proofs, a standardised format was proposed to improve interoperability of Merkle proofs between applications across the BSV ecosystem.

After first being proposed in June 2020 and passing an initial checkpoint review by the 10 Technical Standards Committee members, the proposed standard data format for Merkle inclusion proofs was drafted by a dedicated workgroup and subjected to several subsequent review phases – including an open public review – after which the standard was published in June 2021. Following the publication of the standard, the TSC has monitored the standard for adoption from businesses to determine its usefulness to the broader BSV ecosystem.

With the Merkle proof standardised format now in use across three prominent ecosystem applications – the Bitcoin SV node software, Merchant API (mAPI), ElectrumSV and ElectrumX – the TSC has determined that the standard has reached a sufficient level of adoption to progress to the recommended stage. The standardised format for Merkle proofs is now recommended for all businesses across the BSV ecosystem that utilise Merkle proofs in their application or service. The TSC will continue to monitor the standard for adoption, as well as any potential improvements or modifications that may be required to ensure that it remains useful and relevant for businesses that implement it.

The TSC was established to professionalise the development of Bitcoin technology in order to support major enterprise use and accelerate global adoption. It works to promote technical excellence and enhance interoperability across the BSV ecosystem through standardisation. The committee aims to facilitate industry participation and representation in the development of global standards that will promote technical excellence and enhance interoperability across the BSV ecosystem.

Commenting on today’s announcement, Bitcoin Association for BSV Founding President Jimmy Nguyen said:

‘The work of the Bitcoin SV Technical Standards Committee is vital to professionalising the development of Bitcoin technology for business and ensuring that it is compatible, interoperable and useful. After nearly two years of work, the Merkle proof standardised format becoming the first standard to reach the recommended phase and see real adoption across the BSV ecosystem is a testament to the hard work that has been put in, the processes that have been developed – and more broadly – the importance of the TSC. I would like to extend my personal thanks to the TSC, the members of the Merkle proof standardised format working group and all of the individuals that have contributed to the success of the first BSV technical standard.’

Also commenting, Chair of the Bitcoin SV Technical Standards Committee Steve Shadders said:

‘The first BSV technical standard progressing to the recommended stage – the final stage for technical standards – represents a significant achievement for the Bitcoin SV Technical Standards Committee. The process to get to this stage has been lengthy, but the standard satisfying all of the criteria required to reach the recommended stage is significant and serves as validation, not only for the Merkle proof standardised format, but also for the TSC and the value it brings to the wider BSV ecosystem. Being the first technical standard to reach this stage, there have been several lessons learned throughout the process for the TSC and its working groups, which will benefit the development of all future technical standards – and more broadly – the BSV ecosystem.’


Shortlist of six semi-finalists announced in 4th Bitcoin SV Hackathon with USD $100,000 prize pool at stake


Bitcoin Association, the Switzerland-based global industry organisation that works to advance business with the Bitcoin SV (BSV) blockchain and digital currency, has today announced a shortlist of six semi-finalists in the 4th Bitcoin SV Hackathon. The theme for this iteration of the competition is ‘peer-to-peer applications’, with a USD $100,000 (payable in BSV) prize pool staked for the winners.

One of the premier events in Bitcoin Association’s developer education programme, Bitcoin SV Hackathons are global coding competitions designed to challenge developers to both learn about the technical power of Bitcoin’s original protocol and innovate on the fly. Within a set time period, participants – either as individuals or as part of a team – are tasked with developing an application on the BSV blockchain within the parameters of an overarching theme announced at the start of the competition.

The theme for this iteration of the competition is ‘peer-to-peer’ applications – not just payments, but any type of application that involves direct interaction between participants on the Bitcoin network.  This theme was chosen to refocus development of the ‘peer-to-peer’ aspect of Bitcoin’s original design; although ‘peer-to-peer’ is a key part of the title of Satoshi Nakamoto’s white paper, the P2P elements of Satoshi’s design were disabled and de-emphasised on the Bitcoin Core (BTC) network. Therefore, entrants were tasked with leveraging the recently released SPV Channels service as part of their application to facilitate P2P communication across the network, as well as interacting with the Bitcoin network directly via the Merchant API (mAPI).  Both SPV Channels and mAPI are tools uniquely offered on the BSV network.

The six semi-final entries are:

–  Alien Wallet – an SPV wallet with its own pay-to-order hash function
[Tim Middleton – Australia]

–  Bitcoin Phone – an app for broadcasting voice data over the Bitcoin network that leverages the non-finality of nSequence to enable close to real-time data streaming
[Joe Thomas – Canada]

–  BitCommit – an application for trustless fitness competitions using micropayments and smart contracts
[Gary Miller and Vince Miller – United States]

–  CATN8 – a micropayment-enabled online video platform with a full peer-to-peer SPV wallet implementation
[Marcel Gruber – CanadaDave Foderick – United States; Thor]

–  TimeKet – an SPV wallet combined with a reservation and payment validation system [Joonyeong Park – CanadaYoungjin Jang – JapanSeyoung Jang]

–  TKS Pnt – a point tokenisation system for use by merchants and their customers
[Meta Taro – Japan]

From this shortlist of semi-finalists, three finalists for the 4th Bitcoin SV Hackathon will be selected and announced on August 24.

The three finalists will be invited to present their projects at the upcoming CoinGeek New York conference, October 5 – 7. The Hackathon Final Round presentations will be on Day 1 (October 5) of the conference, with winners announced on Day 3 (October 7). The finalists will compete for a share of a USD $100,000 prize pool, paid in BSV – $50,000 for 1st place, $30,000 for 2nd, and $20,000 for 3rd.

Final placings will be determined by a combination of a final round judging panel and audience voting. To watch the final round presentations and have your say in who goes home with first prize and $50,000 in BSV, register to attend CoinGeek New York in-person or online at

Commenting on today’s announcement, Bitcoin Association Founding President Jimmy Nguyen said:

‘This iteration of the Bitcoin SV Hackathon has once again turned in numerous strong entries, each with a unique take on how best to leverage the peer-to-peer aspects of Bitcoin’s original design and the BSV network’s new SPV Channels implementation of P2P capabilities. With a challenging theme and complex requirements to remind developers about the often-forgotten P2P aspect of Satoshi’s intended Bitcoin system, it’s been impressive to see the different approaches employed by our participants. I congratulate all the semi-finalists and look forward to seeing who are selected as the three finalists.’

Also commenting, nChain CTO Steve Shadders said:

‘Working with all-new technologies – just like we tasked participants in the 4th Bitcoin SV Hackathon with doing with SPV Channels – is never an easy proposition. But challenging situations often lead to innovative solutions, which we’ve certainly seen with the standard of entries in this year’s Hackathon. Having worked intimately on introducing the Bitcoin SV implementation of SPV Channels, I’ve been intrigued to see how developers would approach it – and for a first foray with this new technology, I’ve been impressed with the early returns we’ve seen so far.’

To watch the Hackathon finalist presentations and to learn more about exciting developments on the BSV blockchain, register to join CoinGeek New York live in-person or virtually on October 5-7.

Bitcoin Association appoints new ambassadors for Japan and the South Pacific to advance Bitcoin SV


Bitcoin Association, the Switzerland-based global industry organisation that works to advance business with the Bitcoin SV (BSV) blockchain, today announces that it has appointed two new Ambassadors for the Asia-Pacific region as part of its global ambassador programme, with George Siosi Samuels appointed as Ambassador for the South Pacific and Masumi Hamahira appointed as another Ambassador for Japan.

Bitcoin Association Ambassadors are experienced professionals from the Bitcoin SV ecosystem who work to raise awareness and improve understanding of the Bitcoin SV blockchain and BSV digital currency, as well as the power of the original Bitcoin protocol to support a massively scaled distributed data network for the world. With today’s additions, there are now 22 Bitcoin Association Ambassadors representing 23 different countries and territories.

George Siosi Samuels is the managing director of Faiā, a community tech consultancy working to bridge gaps between communities and technology, particularly in small and developing nations and regions. Faiā is working together with BSV ecosystem companies nChain and Elas Digital to help the Pacific island nation of Tuvalu build – using the BSV blockchain – the world’s first national digital ledger to become the world’s first paperless society.  In addition, Samuels is the founder of Honā, a BSV blockchain-based social accountability platform that can be utilised across a range of different use cases, including the ability to improve the productivity of remote workers worldwide.  Honā was voted the #1 judges’ choice during the Draper University Pitching Competition run by venture capitalist Tim Draper’s organisation.

Masumi Hamahira is a veteran financial executive, having spent 22 years working for MUFG – the world’s fifth-largest bank – including in Malaysia.  An expert in the requirements of Islamic Finance, Hamahira also serves on the board of directors for the Chartered Institute of Islamic Finance Professionals (CIIFP). Supporting BSV initiatives in his individual capacity (rather than on behalf of MUFG or CIIFP), Hamihara is an initial member of the Bitcoin SV Technical Standards Committee and already serves as Bitcoin Association’s Ambassador for Malaysia.   Having relocated from Malaysia to Tokyo, Japan, Hamahira now will also act as a Bitcoin Association Ambassador in Japan (adding to efforts of Ken Shishido, the Association’s first appointed Ambassador for the country).

Speaking on today’s announcement, Bitcoin Association Founding President Jimmy Nguyen, commented:

“As Bitcoin SV continues to demonstrate its utility across a variety of business use cases all over the world, especially in countries in Asia-Pacific, we continue to expand our global Bitcoin Association team to help spread the word and support the ongoing BSV growth story. Both George and Masumi have demonstrated ability as leaders in their respective business fields and as strong advocates for BSV, making them ideal candidates to be new Bitcoin Association Ambassadors for the Asia-Pacific region.”

Speaking on his appointment as Bitcoin Association Ambassador to the South Pacific, George Siosi Samuels, said:

“I see huge potential for the Pacific region, not just for BSV adoption, but for the underlying utility of the technology and its ability to offer leapfrogging development that will facilitate future social, cultural and economic growth. While the Pacific region is often overlooked because of its remoteness, I believe that our Pacific nations will be able to draw on our history as master ocean explorers and translate that into mastering the new digital ocean enabled by Bitcoin technology.”

Speaking on his appointment as a Bitcoin Association Ambassador to JapanMasumi Hamahira, said:

“I foresee Bitcoin SV as a driver for innovation as a global public blockchain protocol in the same way that the Internet protocol did, just as I see great potential in Japan for sophisticated corporates to use BSV in new and unique ways. In my new role, I will work to enhance the awareness of BSV among regulators, lawyers, industry associations, developers and academia by leveraging my network as a global banker and working so that we see the beautiful dawn of Bitcoin SV from the Land of the Rising Sun.”
