About this desk
This desk explains what a blockchain application does and which assumptions sit behind its interface. We cover wallets, scaling systems, network changes and experimental work, keeping test environments distinct from production releases.
If you are new to the subject, start with where a wallet’s coins are recorded. Then read what a wallet connection authorizes. Those two concepts help make sense of many product announcements.
We focus on the details a user can inspect: the network, supported asset, requested permission, fee and route back out. A technical innovation can be interesting without establishing that a token is a suitable purchase. The news below follows current developments, while the explainers provide context for interpreting claims about security, performance and the cost of using a network.
