Human Readable Payment Names Via DNS

Noted bitcoin contributor and Spiral grantee Matt Corallo proposed a BIP to render human readable names into payment info using only the DNS protocol for improved privacy and simplicity when compared to existing schemes. The proposal has been well received with active discussion continuing on the pull request.

BIP Land

BIP Land is a flippant flow chart of the process of getting a bitcoin soft fork activated. The site examines the activation process from the perspective of the OP_CAT proposal. It links to tons of informative and cautionary historical events, with a healthy dose of snark. The site is best experienced in first person.

Cluster Mempool

Cluster Mempool is a proposed mempool redesign that aims to solve a few problems with the existing mempool design, including suboptimal transaction eviction, a complicated block construction algorithm, and incentive-incompatible RBF rules. The proposal introduces the concept of a cluster: a group of unconfirmed transactions connected by parent-child links. Clusters are sorted by fee rate in order to easily calculate their chunks, or the portion of a cluster above or below a certain fee rate. This makes block construction and transaction eviction extremely simple (and opposite) calculations. The proposal drops ancestor and descendent limits in favor of a cluster size limit. It also makes the CPFP carve-out infeasible, which, we hope, can be replaced by v3 transactions.


Synthetic Commodity Money

This paper by famed economist George Selgin introduces a new categorization scheme for forms of money. The novel application of this scheme highlights a previously unexamined category of money that Selgin calls a synthetic commodity money. He defines a synthetic commodity as one which has a combination of absolute scarcity and no non-monetary use. Selgin examines the Iraqi Swiss Dinar as a historical example and bitcoin as an ‘almost ideal synthetic commodity money’.
