The third day of the Bitcoin 2025 conference, which took place on May 29, 2025 at the Venetian Convention Center in Las Vegas, was the last day of this event and focused on technical, social and ecological aspects of Bitcoin. The conference, which was the largest global gathering of Bitcoin enthusiasts, attracted over 35,000 participants and included a wide range of topics – from technological innovation to regulation and adoption of cryptocurrencies.
Technical sessions: second layer solutions and Bitcoin scalability
The third day of the conference began with technical sessions, which continued topics from previous days, such as Bitcoin Layer 2 (L2) and scalability. The conference agenda, according to Coinpedia, pointed to special interest in L2 solutions, such as Bitvm2 and Lightning Network, which are of key importance to increasing Bitcoin’s bandwidth and enabling new applications, such as DEFI on Bitcoin.
“State, Settlement & Scaling: Does Bitcoin Need Optimization?”
This panel, described in Maxim, focused on the question of whether Bitcoin needs further optimization in scaling, settlement and state management. Experts have discussed how solutions such as Bitvm2 and Lightning Network can increase Bitcoin’s bandwidth, maintaining its decentralization and security. The discussion included technical details of Bitvm2 Bridges, which enable more advanced smart contracts on Bitcoin, and their potential use in decentralized finances (BTCFI).
“Bitcoin Under the Hood for Mass Adoption”
This session, also mentioned in Maxim, focused on the technical aspects that must be refined to make Bitcoin more accessible to the mass user. The speakers discussed Taproot Assets and the development of Lightning Network, especially in the context of Tether’s recent involvement in this technology, which opens new possibilities for payments and transfers on Bitcoin.
Discussions about privacy and freedom on the web
Privacy was one of the key themes of the conference, especially in the context of growing concern about surveillance on the Internet and the role of Bitcoin in the protection of civic freedom.
Lawrence Lepard (Equity Management Associates, LLC), James Lavish (Bitcoin Opporturnity Fund) and Mark Moss (Market Disrupts) raised the issues of privacy protection in the era of digital surveillance. Speakers discussed the role of Bitcoin and related technologies, such as NOSTR (decentralized social network) and Samourai Wallet, in ensuring anonymity to users. The discussion concerned the impact of Bitcoin on defense of civil rights, especially in the context of the recent release of Ross Ulbricht, the founder of Silk Road, who was also a speaker at the conference.
Governance and MEMPOOL policy
Continuing topics from previous days, the third day of the conference included panels regarding the management of the Bitcoin protocol, especially in the context of MEMPOOL policy (the space in which unconfirmed transactions are stored). Jonas Nick (Blockstream), Christian Papathanasiou (QBTC) and Hunter Beast (Surmount Systems Foundation) raised the issues of Bitcoin management, including Mempool policy and Covenant activation. This panel has focused on the technical aspects of these mechanisms, such as MEMPOOL optimization to reduce transaction delays, and controversies related to the introduction of Covenant, which can increase Bitcoin functionality, but arouse concerns about potential complications in the protocol.
Sustainable development and influence of mining on the environment
One of the key topics of the conference, especially on the third day, were issues related to Mining Bitcoin and its environmental influence. Gideon Powell from Choll Inc. He spoke to the use of bitcoin and mining technology to support sustainable energy infrastructure in the USA. He also discussed the topic of how Bitcoin miners can cooperate with the energy sector to create more effective energy networks, using surplus renewable energy to mining.
Alexander of Research Associate, which conducts research on the impact of digital assets on energy and climate under the Cambridge Digital Assets Program, presented detailed data on the impact of Bitcoin mining on the environment. His speech included an analysis of CO2 emissions related to Mining, as well as proposals how the industry can become more balanced, e.g. by using renewable energy.
Sessions about the adoption and influence of Bitcoin on finances
The topic of Bitcoin adoption strategy at the state level in the USA. Byron Donalds, Congressman, and Michael Saylor, a well -known supporter of Bitcoin and founder of Microstrategy, discussed how Florida such as Florida can integrate Bitcoin in their financial systems, and what benefits it can bring to local economies. Senator Cynthia Lummis, known for his pro-shrink position, raised the subject of Stablecoin and their role in separating money from state control. Her speech concerned the potential regulation of Stablecoin in the US and their impact on the adoption of cryptocurrencies.
Conclusions
The third day of the Bitcoin 2025 conference in Las Vegas was a mixture of technical discussions on scalability and privacy of Bitcoin and more practical sessions regarding sustainable development, adoption and regulation. Key topics, such as Bitvm2, Lightning Network, MEMPOOL policy and the impact of mining on the environment, reflect the current challenges and possibilities facing the Bitcoin ecosystem. The presence of speakers such as Michael Saylor, Cynthia Lummis or Alexander from CCAF indicates a variety of perspectives – from technical to political and ecological.
