DAPP Token Inflation Tuning

Packages

• 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: https://bloks.io/account/dappservices?loadContract=true&tab=Actions&account=dappservices&scope=dappservices&limit=100&action=enablepkg

docs

• add CoVax chain section for becoming BP or DSP

• add example chains section of LiquidX chains

• add EOS Block Producer Benchmarks | courtesy of Aloha EOS

• 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 LiquidStorage section

• update LiquidAccounts section

• update LiquidVRAM section

• 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

@liquidapps/zeus-cmd

• 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

@liquidapps/zeus-cmd

• 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

@liquidapps/dsp

• 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 authorization option under dfuse to use the EOS Nation community edition: https://t.me/dfusece | https://eos.dfuse.eosnation.io/

• 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

• add https://www.npmjs.com/package/eosio-push-guarantee to DSP eos-wrapper.js

• fixes

  • add better error handling to CONFIRMING USAGE
