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

In the past the node and the wallet were in the same repo. When the wallet was extracted into a separate repo, integration tests were moved to -
It would be beneficial to provide a simple way to run integration suits as part of node tests too.
There are several possible options (there are some other for sure):

  • Move part of th

The binaries are built with most of the build flags already set, but when building from source you must specify which tags are desired. This is an important step to building a usable binary from source.

These flags should be listed in the docs, with what their use is for the entire system, and whether or not excluding it would break the normal function of the system.

When given a wrong argument, some daemon commands fail with "unknown command" error, instead of a meaningful error message.

Examples of useless error messages:

hard_fork_info abc
unknown command: hard_fork_info abc
Monero 'Carbon Chamaeleon' (v0.15.0.0-57854a3e2)

in_peers abcd
unknown command: in_peers abcd
Monero 'Carbon Chamaeleon' (v0.15.0.0-57854a3e2)

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

As we see:

cardano-sl repo contains how-to doc, how to build daedalus - why isn't this doc in daedalus repo?

It not only makes it harder to find for one looking for how to build daedalus, but also :

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.

In order to better propagate only live blocks to peers, we need to be able to classify blocks as either "new"/"active" or "existing" from the perspective of the network, but from our node.

One way we could accomplish this is to have representatives periodically emit a signed message that gives a fuzzy view into their complete ledger.

One way to construct this fuzzy view is to XOR the hash of

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

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.

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)
