Cryptocurrency
A cryptocurrency is a digital currency that only has value dependent on those who back it. For security, cryptocurrencies rely on blockchaining: a database organized in such a way that records are kept secure through peer-to-peer networks. Each record is kept within a block, and each block holds a timestamp and link to the block before it. The first cryptocurrency was Bitcoin, implemented in 2009 by Satoshi Nakamoto.

While ccxt does a great job unifying most functions / settings, not everything is or can be unified.
I think it would be good to provide a separate wiki/documentation page which documents exchange-specific properties.
The behavior is there now and all is working well - but to find it users need to search through issues (which are not easy to navigate) to find certain exchange-specifics - and o

The underlying exploit to tamper with a blockchain is described there

The fix should be fairly simple:

Clients that are built around the API need some additional information to work effectively. This is the following:
-
Peer list API: show more information about connected peers including the block height / cumulative difficulty of the peer. Basically, so the API provides at least as much information as the server TUI does.
-
Status information: Similarly, the minimum amount of info the stat
As is, it is challenging to account for push amounts in LND. This money should be accounted for in some way.
Changes required:
- Persist push amount on open channel
- Expose push amounts on ListChannels

The wallet is currently configured as defined originally in ElectrumX, there are some docs for it already in there.
Keep in mind that we added new configuration keys and should clean up the unused ones at some point, so we need something easy
Actual docs (https://www.getmonero.org/resources/developer-guides/wallet-rpc.html#get_transfer_by_txid) tells us what get_transfer_by_txid return only transfer object, and did not mention what it return a transfers array too.

The blockchain v2 reactor utilizes concurrency to saturate the bottleneck of writing blocks to disk. This concurrency is internal to the reactor where the reactor itself will launch and manage internal state machines running as go-routines. This configuration makes testing difficult as we don't know when messages processed by internal state machines will be processed and when we can assert that th

I would love to add some new exchanges in there for you (and me) and would be happy to do so with just a little guidance as to which objects you're using for it without me doing a full code dig.
Assuming this is easily extensible. If not, I guess that would be my feature request... lol. Extensible exchange objects with documentation.
For a university school project I will be making some edits to your documentation which will aim to make writing more technical
Please add edits if you would like :)
There are lots of configurable settings in the config.json file.

Where can I find detailed documentation on what the settings do?

Bug Report
Problem
The amount is the first field in a transaction. When you fill this out, and then add recipient by scanning their QR code, the amount is reset.
Expected behavior
Amount is maintained unless user cancels the Tx.
Actual behavior
Set Tx amount.
Scan recipient QR code.
Amount is cleared and must be re-entered.

Is there a way to cancel an order before the unfilledtimeout expires, in a way that the local sqlite database remains consistent with the exchage?
Please note that the RPC command /forcesell or /forcebuy do not help with this. In the case of a SELL, one would like to cancel the SELL order in Order Book before the sale is actually executed. It seems a bit different from forcing a SELL with the RPC

A user asked me on slack if estimatefee returns BTC per Byte or BTC per Kilobyte... honestly I don't know and it's a bit hard to tell. I compared mainnet full nodes bcoin vs Bitcoin Core and observed a wild divergence (outputs below).
From Bitcoin Core help:
Estimates the approximate fee per kilobyte needed for a transaction to begin

Stats Plot Rounding
It look like some currencies have more precision in the mouseover display on the plot than others. For example, EOS shows many digits past the decimal while ETH only shows two. Adding a few more digits would make interpreting the charts much easier. The left plot shows the rounding I'm describing and the right shows the higher precision that EOS displays.

Thanks!
Client.get_historical_klines returns a list of 12 elements,. What do all of them represent and where is this documented?
Documentation only mentions the 5 OHLCV values, unless I am missing something.

Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.

Regarding that Bitcoin Core switched to bech32 as the default format for addresses recently (with release 0.19.0.1), this should also be reflected in the RPC help texts. The change was already done for the RPCs
