A Simple CKB-based dApp
CKB Weekly #12
Hello, welcome to issue #12 of the CKB Weekly, a newsletter about the Nervos Common Knowledge Base blockchain and related technology.
The codes above will allow you to send CKB transactions directly using Metamask (or any other Ethereum wallet).
If you need more complex features like adding multiple outputs, setting data, or adding custom lock/type scripts, you can implement your own transaction builder. If you have more requirements for un-used cells, you can customize your own cell collector based on the Collecter, and it applies to Signer / Hasher / Provider too.
You'll find that almost every part of building transactions is customizable to basically meet most of your needs. We've encapsulated the process of building transactions into build -> sign -> send, and any type of transaction can be created and sent with the given Builder and Signer.
The DApp is running on a separate testnet, reply with your address and we will send you some testnet tokens to try the simplest CKB-based DApp. (github link )
Sparklings
China's Blockchain-based Service Network (BSN) has integrated with six public chains including Nervos, and the developers on those public chain can benefit from BSN’s cheap services, interoperability with other Chinese enterprise blockchains.
Nervos Foundation donated $10BTC to the Grin General Fund - are we expecting Mimble Wimble on CKB soon?
