THORChain Weekly Dev Update for Week 19–02 Nov 2019
1 Rune Fee
Reasoning about gas costs on networks with non-deterministic fee schedules (such as Bitcoin) becomes unnecessarily complex. The issue is that the final gas cost cannot be known ahead of time so the system must cover any variability in the gas cost so that the user can be charged a flat rate. If the user is not charged anything, then the system can be depleted of funds, passing the cost back to stakers. Additionally, swaps below 1 Rune bring negligible economic value to the network and saturate the mempool with low value transactions. As such the solution is to charge a flat 1 Rune fee (or 1 Rune equivalent) on all outgoing transactions (swap and withdrawals). This 1 Rune fee is moved into the Protocol Reserve and increases the network’s future income. When the nodes report on the final transaction, they include the observed transaction fee. This transaction fee is then reimbursed back to the pool that paid for it ( BNB.BNB, BTC.BTC, ETH.ETH etc). There are cases that the outgoing transaction fee may exceed 1 Rune (Bitcoin in high use), but more than likely 1 Rune will be more than sufficient to cover the costs and ensure the network grows its reserves. Additionally, it sets a floor on the minimum transaction that the network will process. A swap of less than 1 Rune will end up becoming a donation to the network.
The team are working on 4 parallel streams of effort. Cross-chain infrastructure has now been merged into a single repo called “THORNode”. * THORChain * Midgard Public API * Threshold Signature Scheme implementation * Front-end Integration for BEPSwap
Much work has been done to refactor and clean up the codebase which will make public audits easier. This includes splitting up the keeper, separating out the events module and more. Smoke tests have been fully-integrated into the test schedule. Safer subtraction and division methods were added to prevent the likelihood of panic events. * [refactor] split keeper funcs/interface into separate files * [tests] use gow * [refactor] Redo how get key works in keeper * [security] require no signers on tx ins * Resolve “ADD: 1 Rune Fee on all Swaps” * [bug] fix smoke tests * [ADD] semantic versioning * [Refactor] Keeper chains * [Refactor] Events Keeper * Resolve “Adds a SafeSub method” * [Refactor] Last Height Keeper * [Refactor] keeper liquidity fees * FIX: Issue 208 * [ISSUE] Get smoke tests to 100%
Midgard Public API
Midgard is now ready for integration into the FrontEnd. The manner in which USD price of assets in now updated to source only from internal pool pricing. This includes BNB.BUSD, BNB.TUSD, BNB.USDS. ROI endpoints are now added. * Fix : Updated our mock data to include a correct BNB address. * Add: Return the date a staker first staked. * Add: Previously missing implementations for pool data (24hr and 12m). * Fix: Several potential query issues. Updates to return the TX date as a UNIX timestamp. * Fix: Additional query updates/fixes. * Fix: Build system * Add: Filtering implementation for TxID and Asset. * Added missing import. * Fix/build issues * Fixed issue with my auto refactor * Add: Filtering updates. DB Config fix. * Add: Missing Staker methods for ROI and earnings. * Added fix to enabled timescale extension * Fix: Added build config for rpc_host * Add: Support to Calculate USD price of an asset. * Added: Health check for mainnet to test that we still have a db connection… * Add: Tests for the recent endpoints work. * jq syntax fix. * Additional jq fixes. * [ADD] Manage docker image on gitlab
Threshold Signature Scheme
The Binance Go TSS library is now fully implemented and deploys in a four-node chain. integrate with new go-tss * 212-issue export private key thus we can use it to start tss * 214-issue consolidate tss keygen and tss keysign config, with our new go-tss… * [ADD] Setup go-tss in genesis docker * [ADD] Have CI run smoke tests on a four node chain with TSS
The frontend makes some final tweaks on the interface, before integrating the Midgard APIs. * Resolve “Update stake page share panel” * Resolve “UPDATE: Network Dropdown Titles” * Resolve “ADD: Sorting of columns in pool list” * Resolve “ADD: Sorting of columns in pool list” * Resolve “FIX: Close token selection drop down when clicking outside” * Resolve “Add redux saga for midgard apis” * Resolve “Update protect price UI” * Resolve “Update wallet drawer”
The next milestone is: ChaosNet: 03 January 2020 on-time
Groestlcoin September 2019 Development Release/Update!
For a more interactive view of changes, click here In our current world; bordering on financial chaos, with tariff wars, Brexit and hyperinflation rife, you can count on Groestlcoin to consistently produce innovation that strikes to take the power away from the few and into the many, even after a full five and a half years of solid development. Here is what the team has already announced in the last 3 months since the last development update:
Groestl Nodes aims to map out and compare the status of the Groestlcoin mainnet and testnet networks. Even though these networks share the same protocol, there is currently no way to directly compare these coins in a single location. These statistics are essential to evaluate the relative health of both networks.
Shows Onion (Tor) nodes
Shows IPv6 nodes
Supports both main net and test net
Node Checker – Check the status of a remote node
Ability to download node data by CSV, JSON or TXT format
Ability to download unique address data by CSV, JSON or TXT format
This is a tool for creating unsigned raw Groestlcoin transactions and also to verify existing transactions by entering in the transaction hex and converting this to a human-readable format to verify that a transaction is correct before it is signed.
Create Raw Unsigned Groestlcoin transactions
Generates a QR code for the transaction
Compatible with most Groestlcoin wallets including but not restricted to Groestlcoin Core and Electrum-GRS
Estimates final signed transaction size
Taking a raw transaction format and shows its Transaction ID, Transaction Inputs and Outputs
AGCore is an Android app designed to make it easier to run a Groestlcoin Core node on always-on Android appliances such as set-top boxes, Android TVs and repurposed tablets/phones. If you are a non-technical user of Groestlcoin and want an Android app that makes it easy to run a Groestlcoin Core node by acting as a wrapper, then AG Core is the right choice for you.
Update to Groestlcoin Core 2.17.2
Switched to native builds via NDK for Groestlcoin Core resulting in a smaller footprint.
Added embedded tor
Added tor pairing support
TOR upgrade bug fixes
Improved blockchain Sync progress using getblockchaininfo verificationprogress
Improved package download progress bar
Added support for external storage access > Android M
Added support for Android Oreo, including new notification mechanism
Bump Fee (RBF) improvements – Implemented a new fee-bump strategy that can add new inputs, so now any transaction can be fee-bumped. The old strategy was to decrease the value of outputs (starting with change). We will now try the new strategy first, and only use the old as a fallback.
Coin Choser improvements
More likely to construct transactions without change (where possible)
Less likely to construct transactions with really small change
Only spend negative effective value coins when beneficial for privacy
Fix long-standing bug that broke wallets with >65k addresses
Windows binaries: Now build the PyInstaller bootloader ourselves, as this seems to reduce anti-virus false positives
Fix performance regression for large wallets
Fix high-DPI issues related to text fields
Trezor – Allow bypassing 'too old firmware' error
Trezor – Use only the Bridge to scan devices if it is available
Hardware wallets – On Win10-1903, some hardware devices with U2F functionality can only be detected with Administrator privileges. A workaround is to run as Admin, or for Trezor to install the Bridge.
The AppImage Linux x86_64 binary and the Windows setup.exe are now built reproducibly.
Fix watch-only wallets that could not bump fee in some scenarios
Faster transaction signing for segwit inputs or really large transactions.
Groestlwallet is designed to protect you from malware, browser security holes, even physical theft. With AES hardware encryption, app sandboxing, keychain and code signatures, groestlwallet represents a significant security advance over web and desktop wallets, and other mobile platforms. Simplicity is groestlwallet's core design principle. Because groestlwallet is "deterministic", your balance and entire transaction history can be restored from just your recovery phrase.
