Simple payment handles like

The Goals

The goals of the paymail protocol are:

User friendly payment destinations through memorable handles

Automatic service discovery/location

Request and response authentication

Permissionless implementation

PKI infrastructure

Security and policy management

Self-hosted or delegated to a managed service

Cross-wallet exchange of single-use transaction output scripts of any construction

Capability extensibility and discovery

bsvalias

The family of related protocols are collectively referred to as the bsvalias protocols. At the time of writing, these include:

(BRFC) BitcoinSV Request-For-Comments Specifications

Describes functionality across the ecosystem. Anyone is free to propose anything with no central authority determining new standards, instead support is expressed through implementation.

Service Discovery

Service discovery consists of two phases. First is Host Discovery which is a DNS based lookup of the responsible host for a given paymail alias. Then Capability Discovery provides the capabilities supported by a given Paymail service instance

Public Key Infrastructure

Allows for the creation of simple “handles” such as [email protected] instead of using long and easily mistaken Public Addresses.

Payment Addressing

Enables a wallet to discover the preferred Bitcoin output script of a receiver using their Paymail handle.

Service Discovery

Service discovery consists of two phases. First is Host Discovery which is a DNS based lookup of the responsible host for a given paymail alias. Then Capability Discovery provides the capabilities supported by a given Paymail service instance

Public Key Infrastructure

Allows for the creation of simple “handles” such as [email protected] instead of using long and easily mistaken Public Addresses.

Basic Address Resolution from the Payment Addressing protocol group

Enables a wallet to discover the preferred Bitcoin output script of a receiver using their Paymail handle.

The paymail brand is reserved for products and services that, at a minimum, implement each of the above.

Extension Protocols

As defined in the BRFC Specifications, anybody can propose an extension to the bsvalias and paymail protocols, and as per the Capability Discovery section of the Service Discovery protocol, implementations can declare support for extensions to allow for cross-wallet processes. Extension protocols are the collection of protocols not contained within the core paymail set defined above, but that are fully compatible with bsvalias protocols and paymail implementations.
