  • [Chain] Learned how to build a REST API to interface with a given chain via HTTP calls

04/07

  • [Chain] Research on internal structure of Tendermint blockchain in order to leverage voting & consensus correctly; TenderMint Consensus Algo
  • [Report] Summarise project report targets in order to structure project milestones appropriately

05/07

  • [General] Meeting with Ghita; decision to tighten scope and move away from a formal user testing study for the actual report.
  • [Tooling] Composed bash script for local env setup
  • [App] Added basic REST API methods (getBalance(), setBalance()) to interact with locally running chain

11/07

  • [Chain] Began work on Task.sol and TaskManager.sol contracts
  • [Chain] Added eris library modules eris-logger & eris-wrapper to facilitate building of Node app architecture

12/07

  • [Chain] Experimented with different data structure implementations, i.e. LinkedList & SequenceList, to find best fit for project
  • [Chain] !Issue! Had to find a workaround for the library keyword bug in the eris platform --> simply turned it into a contract --> less flexible than an actual library type though.

13/07

16/07

  • [Server] Added a test implementation of the Node EventEmitter

17/07

  • !Issue! Eris online compiler broke --> took forever to figure out that port 10113 was viable option because no goddamn documentation of it
  • !Issue! Eris local compiler Docker image did not do anything basically, TOTAL FAIL

18/07

  • [Server] Expanded methods for taskManager.js to match those of the contract

19/07

  • [QA] Added chai + mocha test suite

  • [App] Redux sanity checks -> all good, functioning
  • [App] Added PureListView library class from facebook/f8app
  • [Server] Properly implemented GET /tasks endpoint with async.waterfall() to handle callbacks
  • [App] Establish TaskListContainer component to separate data handling and view props

25/07

  • [App] Added addTask() func to communicate with POST /tasks API bridge endpoint
  • [App] Fixed bug caused by implicit assumption in my test cases that addTask() input will be pre-formatted into HEX
  • [App] Added elementary AddTaskView component

Issues

  • State of Solidity as a bottleneck

  • Didn't make my tests atomic enough -> cascading failures if one test breaks -> lesson for next time

  • Trickiness involved in getting ListViews right in RN -> FB's PureListView helped a lot here to understand optimal structuring and mapping of data flow

  • Started with IDs in contract schema, didn't really need them -> addresses double as unique IDs

  • Should've only done quick mocks of views as sketches and then implemented statically ad-hoc, too much time wasted on now not-implemented views

  • [Chain] !Issue! Had to find a workaround for the library keyword bug in the eris platform --> simply turned it into a contract --> less flexible than an actual library type though.

  • [Chain] !Issue! Tested out the LinkedList implementation and replaced it with the SequenceArray implementation after running into retrieval issues

  • !Issue! Eris online compiler broke --> took forever to figure out that port 10113 was viable option because no goddamn documentation of it

  • !Issue! Eris local compiler Docker image did not do anything basically, TOTAL FAIL

Future Work
