TRST

TRST is an acronym that can refer to different concepts in different contexts. In electronics and computer hardware, TRST commonly denotes the Test Reset input of the JTAG boundary-scan interface (IEEE 1149.1). The TRST signal is used to asynchronously reset the JTAG TAP (Test Access Port) controller, bringing the boundary-scan logic to a known starting state. Its presence and polarity vary by device, and some implementations provide TRST as an optional pin while others reset the TAP through other means such as a Power-On Reset or instructions driven by TMS/TCK.

In the realm of blockchain and cryptocurrency, TRST is the ticker symbol for a token associated with the WeTrust project. TRST was issued as an ERC-20 token on the Ethereum network and served within the WeTrust ecosystem to support features related to social finance and mutual aid initiatives. The project launched around 2017, and the token’s trading and the platform’s direction have evolved over time, reflecting broader shifts in the blockchain space and governance decisions by the project community.

Because TRST can refer to more than one concept, the intended meaning is typically clear from context, whether discussing hardware design and JTAG, or blockchain and cryptocurrency topics. If one encounters the term in a new setting, it is advisable to confirm which TRST is being referenced to avoid confusion.
