v1.5.14

Summary

UPDATE: The 1.5.13 release had a bug in reading transactions. Please upgrade to version 1.5.14. If you are running a node which relies on archival transactions, please re-sync from scratch.

This release is an optional upgrade but is highly recommended.

This will likely be the last release before a hard fork upgrade to change the Proof of Work algorithm detailed in UIP 1.

Changes:

• Update Bootnodes
• Fix Ledger hardware wallet support. Further usage details below.
• Remove redundant storage of transactions and receipts. This will perform a one time "Deduplicating database entries" routine on start up of this version.
• Various removals of unused code and general clean ups
• Fix building with Go >= 1.7

All of the provided binaries are also built using the latest Go 1.10.1+.

Ledger Nano S With Gubiq 1.5.13

• Select the Ubiq app
• Set Settings -> Contract data Yes
• Set Settings -> Browser Support No
• Will show first unused account only
• When the first unused account is used, the next unused account will be displayed

v1.5.12 - Backport security fix from Geth v1.6.5

This is a security release to address an attack vector seen on the Ethereum network. It contains the fix released in Geth v1.6.5.

Change:

• Use a bitmap instead of a hashmap to store the results of jumpdest analysis, and optimise analysis process.

This release is highly recommended as it is a security fix that could potentially take nodes offline if the network is attacked.

v1.5.10 - Flux Difficulty Algorithm - Hard fork required

This is a hard fork release so you will need to upgrade before block 8000.

The previous hard fork was activated without any issue but the Digishield difficulty algorithm is proving to be inadequate. We have coded up a new solution called the Flux Difficulty Algorithm. This is a minor adjustment to Digishield so that it implements throttling which will eliminate the peaks and troughs of the difficulty chart. This works by making an extra comparison with the previous block time and throttling the rate of change. The current Ethereum difficulty algorithm works using the approach of looking at the time of the previous block.

We have been testing this for a few days in our local Testnet and the results look good. We do not anticipate any issues and we are in close conversation with our pool operators.

Thank you for your support and understanding.

v1.5.9 - Adjustments to Difficulty calculation - Hard fork required

This is a hard fork release so you will need to upgrade before block 4088.

We have been monitoring the Ubiq network since launch and have found that the default Digibyte Digishield settings are overly sensitive to the Dagger Hashimoto algorithm so block times are not as consistent as we would like them long term. This issue did not show up in our earlier Testnet testing as this issue does not show up for smaller hash rates.

Since we are a new network, we felt it was right to make the necessary changes to address this issue early on. The network is working fine but we can do better.

The technical details are that we will increase the number of past blocks that we will sample for calculations (up from 30 minutes) and we will decrease the % adjustment.

We have been testing this for a few days in our local Testnet and the results look good. We do not anticipate any issues and we are in close conversation with our pool operators.

Thank you for your support and understanding.

v1.5.4-BETA Testnet

This is also planned to be the final Testnet release so consider it a final Beta release as well

Main changes are:

• Based on the latest geth 1.5.x
• Some minor code clean up and changes.
• Now known as gubiq (instead of gjbsee). Repo link: https://github.com/ubiq/go-ubiq/
• Live testing of monetary policy block rewards (this is opposed to Ethereum and other forks which have a fixed block reward). For now this steps down from 8 to 5 in increments of 1000 blocks. This will be modified in the main network. so in Testnet:
  • blocks 1-1000 = 8 UBQ
  • blocks 1001-2000 = 7 UBQ
  • blocks 2001-3000 = 6 UBQ
  • blocks 3001 onwards = 5 UBQ
