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.

Tue May 07 14:57:20 +0000 2019

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!

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.

“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”
