DAPP Token Inflation Tuning

  • it is now possible for the community to actively tune the DAPP Token Inflation rate

  • this inflation tuning is facilitated by DSP's creating new packages that have a configurable desired inflation rate. any changes to the DAPP Token's inflation rate is in effect for all providers

  • all existing packages retain the default annual inflation rate of 2.71%

  • a new package may select any rate between 0.0 and 5.0%

  • DAPP Token holders participate in the tuning mechanism by staking to packages that have an inflation rate they support

  • the final inflation rate is calculated as a weighted average of DAPP staked to specific inflation rates

  • a new table packagext has been added to store a packages selected inflation rate and quota cost for actions, which is indexed by package_id, service, and provider

  • the DAPP token inflation rate is recalculated with every stake and refund action

  • package inflation rates may not be changed after they are registered

breaking changes

  • to use new dfuse push_transaction, must compile consumer contract with new version of dappservices contract

  • if DSP package is not enabled in package table, signaled with boolean "1", then service will throw error on DSP, DSP package may be enabled with the enablepkg command:

  • add CoVax chain section for becoming BP or DSP

  • add example chains section of LiquidX chains

  • use eos 2.0.5

  • update documentation to support zeus_boxes refactor

  • add chain-threads=8 eos-vm-oc-compile-threads=2 to nodeos example config.ini in docs

  • add get_table_packagext and get_table_packagext_by_package_service_provider to dapp-client section

  • add http-max-response-time-ms = 500 to config.ini settings to avoid deadline 2020-07-20T18:07:39.110 exceeded by 10us error

  • add supported primary key types for dapp::advanced_multi_index

  • add example of instantiating dapp::advanced_multi_index

  • support new Kylin account creation query

  • use 8887 instead of 8889 for state history port to match DSP docs

  • skip 01-dapp-client.js if built

  • add price feed example, price feed uses LiquidHarmony's oracles and LiquidScheduler's cron to fetch a price periodically and only use CPU when the price has changed from the last recorded price by more or less than 1%

  • add '--eos-vm-oc-compile-threads=4' and --chain-threads=4 to local nodeos

  • update zeus to modularize logic into zeus_boxes directory making zeus more like npm, to create or unbox a new box start with zeus box create [name] then if you wish to unbox and existing box zeus unbox <BOX>

  • zeus now offers versioning of boxes

    • zeus now offers optional zeus unbox <BOX>@[VERSION]

    • can add and remove boxes with zeus box add <BOX> [VERSION] [URI] zeus box remove <BOX> [VERSION]

    • to update an existing box, run zeus unbox <BOX>@[VERSION], if no version specified, latest used, will unbox everything again with new version

    • to only add new boxes, unbox after update with --no-update

  • add zeus start-localenv --phase 01-dapp-client --phase option to target start a specific phase of the localenv

  • fixes

    • if Mac, detect and skip --eos-vm-oc-enable flags as they are not supported

    • fix endpoint link for replay-contract.js file

  • document ability to use dfuse for cleanup script

  • add typescript compile step for dfuse

  • add zeus box create section to zeus getting started section

  • update LiquidStorage upload file example with new params

  • add eth_keys_per_consumer = [{ETH_PRIVATE_KEY_CONSUMER1:PRIVATE_KEY_HERE}, {ETH_PRIVATE_KEY_CONSUMER2:PRIVATE_KEY_HERE}] to toml

  • prevent non-broadcast action from being broadcast

  • add sidechain section to replay contract

  • add testfetch price feed action / unit test for only using LiquidHarmony oracles for price feed fetch

  • add unit test for 0s unstake time dappservices

  • copy contracts and test folder to root so that zeus_boxes directory can be git ignored

  • add enablepkg command to dappservices unit tests

  • fixes

    • add parseFloat to test rewards dappservices unit test

  • add option to use dfuse web socket and dfuse push_transaction guarantee in place of demux state history node on main DSP instance and supported side chains

    • this enables a DSP to not use a SHiP node and to instead read on chain events from dfuse and to push transactions using dfuse's push_guarantee making transactions more reliable, a free API key is suitable enough to support low levels of traffic

    • to use the dfuse backend, under the new dfuse section of the toml file, set enable to true and provide an api key

    • to use the dfuse push guarantee, set the push_enable to true and provide a dfuse api key

    • to use both, enable both

    • add dfuse section network to toml, select supported dfuse network: testnet (eosio testnet), kylin, worbli, wax

    • add debug to dfuse section to enable dfuse debug logs

  • if dsp head_block set to 0, dsp will pull head block from get_info RPC call automatically for demux

  • throw error if package not enabled for DSP services

  • enable cleanup script support for sidechain

  • add replay-contract-hyperion.js | thank you to Christoph Michel

  • add max_request_retries option to config.toml, specifies how many times to retry a blocking DSP actions such as an IPFS warmup or oracle request

  • add liquidstorage_upload_limit to config.toml, allows specification of Liquidstorage upload size limit

  • fixes

    • add better error handling to CONFIRMING USAGE

    • fix async/await procesFn issue

    • fix replay contract script to enable DSPs to replay contract vRAM/IPFS data to populate a new IPFS instance

    • fix 0xANON payer empty object issue

  • patch new secondary index RPC API support

  • updated Dapp Client to support cross chain Liquid Accounts

  • add dfuse as option for dapp client, able to pass API key, push guarantee, and network

  • add push_transaction push guarantee function to lib

dappservices contract

  • added required service pending console output to assertion message as dfuse does not return pending console output

  • added always false assert service pending console output to assertion message as dfuse does not return pending console output

DSP Services:

  • add cross chain support for LiquidAccounts using LiquidX

  • add time to live option for zeus vaccounts push-action command

  • add small / large photo and small video upload and read unit tests to LiquidStorage

  • configure options object to be passed, updated unit test

    • add optional rawLeaves IPFS client option for backend API, example, and client-library

  • run exponential backoff forever, was 10 retries max

  • add shouldAbort eosio::check handler for rescheduling cron without CPU

  • patch new secondary index RPC API support

  • updated Dapp Client to support cross chain Liquid Accounts

  • add get_table_packagext and get_table_packagext_by_package_service_provider examples and logic to client
