  • Setting up NANO test network?

    Setting up NANO test network?

    Hello,

    I'm new to NANO and am interested in setting up a "test" network with just a couple of docker nodes that I can use the CLI or web interface to connect to and explore to get a feel for how things work. I want to learn how to setup the TEST network, configure it, and then interact with it as some initial steps.

    I am trying to determine how NANO compares to STEEM, BITSHARES, and EOS as far as transactions-per-second and scalability.

    Is there any documentation on this?

    Also, I am seeking a NANO forum or other place to discuss NANO core code development as well.

    Any assistance or input would be greatly appreciated Thanks and have a great day,

  • Can't start the wallet on Ubuntu 17.04

    Can't start the wallet on Ubuntu 17.04

    I was using rai_wallet a few months ago without any problem, but now I get: $ ./rai_wallet Aborted (core dumped)

    I think it's caused by Ubuntu upgrade to 17.04 My current kernel is: Linux 4.10.0-21-generic #23-Ubuntu SMP Fri Apr 28 16:14:22 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

    Any thoughts how to fix it?

  • Would Raiblocks applications (malicious or not) be vulnerable to private key leaking?

    Would Raiblocks applications (malicious or not) be vulnerable to private key leaking?

    I was looking about the sign algorithm Ed25519 and found this issue: https://github.com/jedisct1/libsodium/issues/170

    Lets imagine the flow below:

    1. Origin wallet sign a transaction and broadcast it
    2. Some bit(s) could flip during the signing
    3. Destination wallet receives the transaction and invalidates it because of wrong signature
    4. Origin wallet creates the same transaction again and re-broadcasts it
    5. Destination wallet receives the transaction ok. And as a prize, it could extract the origin wallet's private key

    Having some bits changed during the signing happens, a lot. And happens more on mobile devices, mostly on iOS for example.

    It could expose the private key, not just to the destination, but for all network.

  • Change storage technology

    Change storage technology

    Why

    Currently one of the largest costs of running a Raiblocks node is due to the large amount of IO needed just to keep up with the current write rate.

    General Info

    Disks can do ~75 to 100 iops per second, or 120 Megabytes per second (sequential io). Consumer SSD's can do ~10K iops, or 375 Megabytes per second of IO.

    Problem Description

    Bootstrapping currently requires ~1k iops and 3 megabytes/s. So LMDB is generating a lot of very small writes for every block, but it's not actually writing much data. The write rate would be easily done on a single spinning disk if the IO's were structured differently.

    That's not ideal for this usecase where we are more concerned with being able to sustain a large write rate. There's a very large temporal distribution of data; newer data is more likely to be read while old data is less likely to be read. So we should choose a data-storage technology that allows for very cheap writes, has relatively cheap reads on recent data, and can scale to large amounts of data.

    LMDB is a memory mapped B-Tree. It makes for some very very fast random reads; however it's expensive for writes.

    Log Structured Merge Trees however have the exact properties that we're looking for. See: The advantages of an LSM vs a B-Tree

    Log structured merge trees allow writes to come in at a fantastic rate, and only generate a small amount of larger IO's. So we should think about replacing LMDB with a log structured merge tree. The best in breed currently is RocksDB. It also has the added advantage that it can compress blocks.

    Suggested Solution

    1. Add RocksDB
    2. Add ZSTD
    3. Configure RocksDB with universal compaction,
    4. Add a flag to allow using RockDB.
    5. After it's all tested and shown to be working remove the LMDB code.

    Steps to reproduce the issue:

    1. Start a new rai node
    2. Run iostat -dxt 5
    3. Notice the very very small IO's being issued.

  • Add a new message type

    Add a new message type "bulk_pull_blocks"

    This patchset adds a new message type "bulk_pull_blocks" (0x09) which allows one to request from a node a range of blocks (min_hash to max_hash). Alternatively, the checksum for a range of blocks can be requested to determine if it is likely that there are new blocks in that range that need to be pulled.

    Further, a limited number of blocks can be requested by specifying a non-zero "max_count" argument.

  • Remove PoW requirement on RECEIVE tx

    Remove PoW requirement on RECEIVE tx

    Discussed in Issue 360

    Requiring PoW on RECEIVE txs puts a large burden on services that accept XRB deposits, and if a user were spammed with penny-sends then it is difficult for them to clean it up.

    Having a min PoW on RECEIVE txs makes it pretty efficient to identify and discard spam quickly, however it does not prevent spammers from broadcasting underworked RECEIVE txs. Because RECEIVE txs must match 1:1 with SEND txs there is no risk of ledger spam on the RECEIVE side. Only SEND can be the source of ledger spam. PoW does not prevent network spam.

    Instead of using PoW as one of the first criteria to validate RECEIVE txs, a bloom filter can be used first to confirm that the SEND being claimed is still pending. The bloom filter will have to match for all pending SEND's. If the bloom filter check returns "this RECEIVE's SEND is definitely not still pending" then this spam RECEIVE is discarded. If the filter says it may still be pending then this spam check is passed.

    There may be slightly better ways to implement this, or maybe it already is implemented, but the gist of it is that PoW on RECEIVE txs is hurting a whole lot more than it is helping so it should be disabled.

  • Unable to receive pending funds

    Unable to receive pending funds

    Hello,

    Installed RAI Desktop Wallet, created password and backed up seed. Got account address and sent some XRB to it. It was very far out of sync and even after days of running non-stop it did not catch up even though it's installed on SSD and fast network. I downloaded latest ldb and replaced. I then imported my wallet using seed. After import my previous account address is no longer shown in the wallet. The accounts page does however show my pending deposit in the Wallet Pending section. The use of the more recent ldb allowed my local wallet to finish syncing with the blocks, still no change in accepting my funds and again I still cannot see the original account address in the GUI wallet.

    As a troubleshooting step I started using RPC commands. Account list shows the original account address, it shows the pending funds but attempting to run a receive command on the transcation returns this: { "block": "0000000000000000000000000000000000000000000000000000000000000000" }

    Any ideas?

  • Improve polymorphism in `rep_crawler::cleanup_reps()`

    Improve polymorphism in `rep_crawler::cleanup_reps()`

    Broken Polymorphism

    The method rep_crawler::cleanup_reps() is responsible for removing representatives that have inactive channels. The problem is that a channel cannot be asked whether it is closed, so rep_crawler checks for the concrete type of the channel and asks for example tcp_channels whether that channel still exists. Checking the concrete type of the channel breaks polymorphism!

    Here is the relevant code snippet:

    void nano::rep_crawler::cleanup_reps ()
    {
    	std::vector<std::shared_ptr<nano::transport::channel>> channels;
    	{
    		// Check known rep channels
    		nano::lock_guard<nano::mutex> lock (probable_reps_mutex);
    		auto iterator (probable_reps.get<tag_last_request> ().begin ());
    		while (iterator != probable_reps.get<tag_last_request> ().end ())
    		{
    			if (iterator->channel->get_tcp_endpoint ().address () != boost::asio::ip::address_v6::any ())
    			{
    				channels.push_back (iterator->channel);
    				++iterator;
    			}
    			else
    			{
    				// Remove reps with closed channels
    				iterator = probable_reps.get<tag_last_request> ().erase (iterator);
    			}

    			probable_reps.get<tag_channel_ref> ().erase (*i);
    		}
    	}
    }
    

    Possible Solution

    A possible fix for this design issue could be the following: tcp_channels currently removes inactive channels in its purge (...) method. It however does not change the state of the channel.

    A better design would be, if tcp_channels::purge() would actually close the channel and if there was a channel::is_closed() method. rep_crawler could then just ask the channel whether it is closed and it would not need to know the channel type. The resulting cleanup_reps() method could look like this:

    void nano::rep_crawler::cleanup_reps ()
    {
    		// Check known rep channels
    		nano::lock_guard<nano::mutex> lock (probable_reps_mutex);
    		auto iterator (probable_reps.get<tag_last_request> ().begin ());
    		while (iterator != probable_reps.get<tag_last_request> ().end ())
    		{
    			if (iterator->channel->is_closed ())
    			{
    				// Remove reps with closed channels
    				iterator = probable_reps.get<tag_last_request> ().erase (iterator);
    			}
    		}
    }

  • Add

    Add "threshold" option to representatives RPC command, and a new "representative_count" command

    Summary

    The representatives RPC command currently only has count and sorting options. While sorting does move very small / 0-weight reps to the bottom of the list, it does not preserve the original ordering of the list, and still returns very-small-weight reps if count is set high enough. The threshold option would only return representatives with weight greater than or equal to x.

    representative_count would, as the name implies, return the total number of representatives. Currently this is only possible using representatives with count=-1, and manually counting up the total.

    What problem would be solved by this feature?

    These additions would benefit any software which needs to access data regarding network representatives beyond a superficial level. Besides being much more convenient for developers, this would also majorly decrease bandwidth requirements for any software using this data which does not have access to a local node.

    Are there any previous requests for this feature?

    As far as I'm aware, there has been no discussion of adding these particular features.

    Do you have a suggested solution?

    Yes, add threshold as an option for the representatives RPC, and implement representative_count functionality.

    If this feature is approved, would you be willing to submit a pull request with the solution?

    I am willing to collaborate

  • Bidirectional channel communication

    Bidirectional channel communication

    Due to a peculiar design / bug, we currently open two connections (sockets) per one peer for realtime communication. One socket is used for sending messages and the second one is used for receiving. This complication is needless and it degrades communication in situations where one of the peers is behind NAT. This PR aims to solve this issue.
