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.

#17851 added std::to_string to the list of locale dependent functions, along with a large number of usage exceptions. It was pointed out that some of these usages are actually likely bugs, and should be fixed rather than hidden as exceptions.

Clients that are built around the API need some additional information to work effectively. This is the following:

  1. 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.

  2. Status information: Similarly, the minimum amount of info the stat

Background

When dynamically rejecting an inbound channel, the connecting peer should receive an indication of why their request was rejected.

Examples of existing messages:

  1. Minimum channel size not reached
  2. Multiple channels not supported

Steps to reproduce

  1. Open a channel that will get dynamically rejected
  2. Get generic rejection message

Expected behaviour

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
confirmation within conf_target blocks if possible

I'd like to see an Ethereum address added to the custom property of the FUNDING.yml file for GitHub Sponsors. This would allow a canonical address to send funds to. For example, I'm building a project that allows developers to setup one recurring donation that is split between all of their dependencies with an Ethereum address: https://sustainus.io

Hi!

I was using get_batch_stock_quotes on regular basis and suddenly it stopped working (without updating av or any other python libraries). Calling the function for some list of stocks produces the error:

raise ValueError(json_response["Error Message"])

Hi all and Carles,

I think we should forget about the ping and pongs and pong width etc... It's too confusing and useless (especially for newcomers).

Ping width = width
Pong width = target

So using Boomerang or PingPong, you set up a width and a target, and it's more clear for everyone.

So when you do PingPong you buy at a price and want to sell at price + target (width pong). Once yo

Hi,

I the documentation here it says: "Support for accessing multiple exchanges per algorithm, which opens the door to cross-exchange arbitrage opportunities."

Does catalyst really support multiple exchanges using the same algorithm? If so - how this can be done? (no documentation for it)

Thanks!
