Testnet 0.7.4

Testnet 0.7.4

This release fixes a regression introduced in 0.7.3 which caused transactions to be always rebroadcasted to peers, even when the transaction had already been added to the UTX before, which caused network load to increase exponentially and in the end resulted in an OutOfMemoryError.

Other notable changes:

• Pending balance for an address, which pessimistically includes all balance decreases caused by transactions in UTX
• Numerous Matcher improvements
• Increased max transaction length to accommodate Issue Transactions
• Bumped dependencies to newer versions

If you are updating from 0.7.3, it should be safe to keep blockchain data. Otherwise, please remove blockchain.dat and state.dat upon update.

Testnet v0.7.3

Testnet 0.7.3

• MakeAssetNameUnique transaction was removed
• New validation rules for CreateAliasTransaction

We've removed MakeAssetNameUnique transaction because it's considered useless. Also we've hardened alias string constraints, now it's limited to lower case ASCII letters, numbers and 4 special symbols ('.', '_', '-', '@').
Because of this we are going to restart Testnet from last valid block. Please, remove blockchain.dat and state.dat upon update.

Testnet v0.7.2

Testnet 0.7.2

• New network layer
• Data storage optimizations

Internal data structures in blockchain.dat, state.dat and peers.dat were changed, please, remove those files before starting this version.
Default file locations were changed.
Some configuration parameters were removed and few were added. Please refer to Whats new in version 0.7.2 document to change your existing configuration file accordingly.

MAINNET Version 0.6.5

INFO

This is a bug fix release.
This version will work on existing blockchain.dat.
You don't have to drop the blockchain.dat if you are not on a fork. But it's always better to download the blockchain from the scratch to ensure the correctness of the state.

• Rollback issue that leads to forks was fixed.
• Few DEX Matcher fixes.
• Nodes connectivity issue was fixed.

You can download the latest blockchain snapshot (496600 blocks).

Testnet v0.7.0

Testnet v0.7.0

WARNING

Please, remove existing blockchain.dat file and download blocks from the network.

NOTE 1
Probably, this is the last time we ask you for removing the blockchain file. Starting from this release we have separated files for storing blocks and state. This allows rebuilding node's state from the existing blocks. So, in future, we will be able to update state structure without spending time on downloading blocks from the network.

NOTE 2
We have joined two DEBs into one and completely rewrote scripts in it. Now, the package detects the kind of init system used and installs accordingly. We've changed the location of node's data. We will update documentation shortly.

• State storage was completely reimplemented from scratch
• Block storage and state storage in separate files
• New Alias Transaction allows to create an alias to the account (will be activated on Testnet on Mon, 1 May 2017 00:00:00 GMT)
• New DEB package

v0.6.4

Version 0.6.4

WARNING

You have to remove existing blockchain.dat file before installation.
To speed up update of the node you can download blockchain-mainnet-457000.zip file. Please, extract blockchain.dat file from the archive and replace existing file.
You can verify integrity of downloaded blockchain by checking it's signature in file blockchain.dat.sha1.

WARNING

Leasing balances will be RESET to actual Waves balances on MAINNET in block #462000 and on Testnet in block #51500.

New consensus rules will be activated on MAINNET on Fri, 21 Apr 2017 10:00:00 GMT and on Testnet on Wed, 19 Apr 2017 00:00:00 GMT.
