Self-evaluation

Use the assessment below to help you evaluate your current knowledge. Where you find gaps, use the resources on this page to bridge the gaps.

Answer true or false for the following statements. Use the bullets below the statements to create your learning plan.

• I am familiar with and conversant about blockchain technology.

  • If false, see content in Blockchain 101.

  • If true, see content in RChain blockchain

• I am familiar with Rholang and have written Rholang code. I am comfortable talking about this with others on the team who are working on implementing Rholang on the RChain platform.

  • If false, see content in Rholang 101

  • If true, move on to another topic.

• I am familiar with Proof of Work Consensus and Proof of Stake consensus, and am comfortable talking about it with others on the team who are working on implementing Casper to the RChain blockchain.

  • If false, see Casper 101

  • If true, move on to another topic.

• I am familiar with the LADL algorithm and can talk about it at a high level.

  • If false, see LADL 101

  • If true, move on to another topic.

• I am familiar with Scala and have written Scala code. I am ready to contribute to Scala-related work on the RChain project.

  • If false, see Scala 101

  • If true, see RChain flavor of tagless final  .

Getting started with Scala and RChain Scala style guide

RChain flavor of tagless final style

The development team has adopted a common approach to use of the tagless final style on the RChain project. Members of the team suggest the resources below to help you get started. The other best practice is to look at code in the project and to use the team as a resource.

• Introduction to tagless final

• Exploring tagless final patter for extensive and readable Scala code

• Optimizing tagless final: saying farewell to free
