I will be attending and speaking at next week’s Wyoming Legislative Blockchain Task Force meeting in Jackson on Monday & Tuesday. They have been doing great work creating laws that support blockchain based startups. Agenda at details button on https://www.wyoleg.gov/Committees/2019/S3

There is a lot of discussion lately about blockchain-less DIDs: here is one.
Impressive overview by @_prestwich on how bitcoin-core decides what transaction scripts are “standard” and thus are shared by the P2P network before being accepted into a block vs. those that may be valid to mine but are not shared. Much I did not know! https://prestwi.ch/the-bitcoin-nonstandard/
Replying to @mwilcox
This is not censorship as it does not limit individual’s ability to transact. It is attack-resistance, as all public blockchain designs have to have some limits or the sybil will censor by denial of service.

After researching best practices for simple cold storage, I discovered an useful option in some states where they offer safe-deposit boxes with joint-tenancy with right of survivorship or tenancy-in-entity. Proposed it today at Wyoming Blockchain Task Force passed motion.
This is only the first step, as research by the LSO will need to be made, and it will be brought up with actual language for further consideration at next Wyoming Blockchain Task Force Meeting in July. Takes time but nice to be heard!
These are our best practices for simple custody cold storage where we suggest the appropriate use of a safe deposit box: https://github.com/BlockchainCommons/SmartCustodyWhitePapers/blob/master/%23SmartCustody-_Simple_Self-Custody_Cold_Storage_Scenario.md Joint tenancy will address some issues.
I’m quite pleased to report that today the Wyoming Blockchain Task Force has agreed to investigate this #KeyAreNotAssets issue and will propose language for protection of keys at their next meeting, for possible proposal in next legislative session. First step in the process! 👍

For this initial law, not much. The difference would be that the demand for keys comes only later in the process after failure to deliver, if revealed is only ‘in camera’ private to the judge. But contempt of court still possible if you don’t satisfy judge. A good start on issue.

Fincen has released new guidance on what qualifies as a money transmitter. Some good, some bad. 👎Lightning nodes that charge a fee are likely money transmitters. 👍First I’ve seen from a US regulator that has a nuanced opinion on multisig. https://www.fincen.gov/sites/default/files/2019-05/FinCEN%20Guidance%20CVC%20FINAL%20508.pdf
“If the multsig wallet provider restricts its role to creating un-hosted wallets that require adding a 2nd auth key to the wallet owner’s private key in order to validate & complete transactions, the provider is not a money transmitter because it does not accept & transmit value”
This is perfect for some multisig #SmartCustody wallets like @GreenAddress, and I think for @unchainedcap’s vaults https://www.unchained-capital.com/vaults/ but there are are some other custodial solutions that may not qualify…
“On the other hand, if the person combines the services of a multiple-signature wallet provider and a hosted wallet provider, that person will then qualify as a money transmitter.”

(d) enter a formal agreement with, at a minimum, the seller or creditor that provided the goods or services and also receives the funds.”
Replying to @Xis10tial1
Thus Lightning nodes seem unlikely to qualify under the payment processors exemption. I personally feel a node is charging fees to incentivize the support the ecosystem, and should be exempted, but that is not how this guidance seems to interpret them, but IANAL.

Eckman writes about how when you witness someone experiencing an emotion, you get a form of it yourself. I believe many of these genres of videos allow people to vicariously “feel” like they are doing it so they don’t have actually do it themselves. Similar to woodworking videos.
Replying to @kchironis
This does connect to narrative design as many games do this too. You see a character experience an event and a simulated emotion or emotion-like reaction and the player will experience a form of it in their mirror neurons.

If you must store passwords on paper (I use titanium) use waterproof paper and permanent ink. Also, human randomness is bad. Use either a cryptographic source of randomness (usually 128 or 256 bits) or EFF Dice Words (77 bits). https://www.eff.org/dice

We do offer options that can help against stronger adversaries (at the price of process fatigue & loss of resilience) however the power of nations to attack their citizens is huge. So I don’t work hard to mitigate attacks by my own nation, hoping for rule of law to be sufficient.
