Capacity increases for the Bitcoin system

Bitcoin Core developer Greg Maxwell recently published a post on the bitcoin-dev mailing list outlining a proposed scalability roadmap for the Bitcoin network and protocol going forward. Here’s the TL;DR:

I propose we work immediately towards the segwit 4MB block soft-fork which increases capacity and scalability, and recent speedups and incoming relay improvements make segwit a reasonable risk. BIP9 and segwit will also make further improvements easier and faster to deploy. We’ll continue to set the stage for non-bandwidth-increase-based scaling, while building additional tools that would make bandwidth increases safer long term. Further work will prepare Bitcoin for further increases, which will become possible when justified, while also providing the groundwork to make them justifiable.

Since publishing this roadmap, over 30 current and past contributors to Bitcoin Core have signed on in support of the proposal. Read the full proposal in the link below to learn about the future of Bitcoin scalability.

Bitcoin attack vectors explored in new report

 

The non-profit RAND Corporation has published an extensive report entitled, “National Security Implications of Virtual Currency.” In the report, they explore how “non-state” actors might employ the use of virtual currency technology to their advantage, and how nation-states might respond if such use of virtual currency becomes a threat to national security. As Bitcoin and other cryptocurrencies continue to gain adoption and influence, potentially disrupting trillions of dollars in profits across a wide range of industries built on artificial scarcity, middlemen, and trusted third parties, it’s important for the communities supporting these networks to be aware and vigilant in defending against attackers employing the methodologies mentioned in this report. You can learn more about these attacks and how the Bitcoin community might defend against them by reading the full PDF report linked below.

Redditor “aberrygoodtime” has created a great summary of the possible attacks on Bitcoin mentioned in the report:

Segregated Witness presentation at SF Bitcoin Devs
