# Key Points from #hplusroadmap IRC Discussions

• Blockchain innovation was discussed, focusing on designs where wallets carry UTXOs (unspent transaction outputs) with proofs while the blockchain only maintains UTXO commitments, potentially solving storage scaling issues by reducing burden on miners and full-nodes.

• Participants shared personal nootropic regimens ("stacks"), including combinations of Adderall, creatine, theanine, alpha-GPC, rhodiola, oxiracetam, Ritalin, NSI-189, and vitamin B12, with debate about whether stimulants should be classified as true nootropics.

• The community discussed cognitive enhancement medications in depth, with one participant noting atypical responses to Adderall that enabled basic communication functions, suggesting significant executive functioning impacts that may not generalize.

• Neurofeedback was explored as a treatment for attention issues, with specific hardware recommendations including Pocket Neurobics' HEG/EEG devices and the Q-Wiz amplifier as cost-effective options.

• A critical examination of DIY biology communities emerged, questioning organizations that claim to be community-focused while imposing membership fees and requiring government approval for projects.

• Recent pharmaceutical advances were noted, including daclatasvir/sofosbuvir for hepatitis C and tenofovir/emtricitabine for HIV pre-exposure prophylaxis, showing the community's interest in tracking medical breakthroughs.

• Kanzure shared a draft modafinil usage survey for 2015, indicating ongoing systematic efforts to track cognitive enhancement drug usage patterns within the transhumanist community.
