Blockchain Explorers

My wallet balance does not match the explorer balance for my address, why?

A wallet can have multiple addresses, and you can have so-called "change addresses" (see https://en.bitcoin.it/wiki/Change) which will be generated automatically whenever you spend less than you have.
Those "change addresses" are part of the Bitcoin (and alt-coins) anonymity features, are known only to your wallet and can hold more than small change.
They are not displayed in the usual wallet UI, but you can typically view them by going to the debug console and typing "listunspent".

Our explorers can sometime guess those addresses, but not all the time, and only ofter after the fact. When that happens an address will be aggregated in a "guesstimated wallet".

What are "guesstimated wallets"?

Guesstimated wallets are a unique and experimental feature of our explorers.
The "guesstimation" involves a taint analysis on the blockchain transactions, and tries to guess which addresses are (or were) part of a given user wallet, to provide a more accurate rich list.

The way taint is accumulated by a blockchain is quite random, and usually is not significant for individual's wallets, however Exchanges and major processors can naturally accumulate a lot of taint over time, so their guesstimated wallets can be meaningful.

Even in the best of cases, guesstimated wallets are an underestimation of a wallet balance, the actual balance of a wallet is at least what was guesstimated, and usually higher.

How are outstanding coins computed? You are showing less/more than there are!

Outstanding coins are computed from the transaction outputs, with sometimes burn addresses being zero'ed (by request, and for publicly documented burns).

The differences usually come from two sources:

  • miner errors, that forget to account for a fee, can lead to an outstanding coin count being slightly lower than it should theoretically be
  • not notified burns, for ICO/ITO/IPO sometimes unpurchased coins are burned, but if we were not notified of the burn address, we did not zero it (yet)

How often are Rich List rankings and balances updated?

Currently they are updated every 6 hours, there is no set time at which the updates happen, it is different for every explorer to spread the workload.

What are those weird wsh_ and wkh_ addresses?

Those addresses are the temporary naming scheme we use for segregated witness outputs, as no standard has yet been established (most advanced proposal seems to be BIP-0173, but it is still a draft.

  • wkh_ prefix is for witness_v0_keyhash (followed by base32 of commitment)
  • wsh_ prefix is for witness_v0_scripthash (followed by base32 of commitment)

We hope that this situation will be resolved soon, and the chosen name scheme will be implemented in the respective RPC APIs, so that how segwit "stuff" is named becomes an unambiguous standard for each blockchain.

API & Integration

Is there a public API?

Yes, all the explorers come with a public API, see the API documentation for more details.

To unlock certain APIs or "live" data, you can request a free API Key.

How can I integrate with MPOS pool software?

There are three MPOS parameters to configure, for chain xyz the parameters will be:

  1. Blockexplorer URL: URL to the blockexplorer website for your blockchain. Will append the blockhash to the URL.
    https://chainz.cryptoid.info/xyz/block.dws?
  2. Transactionexplorer URL: URL to the transactionexplorer website for your blockchain. Will append the transactionid to the URL
    https://chainz.cryptoid.info/xyz/tx.dws?
  3. Chaininfo URL: URL to the chaininfo website for your blockchain.
    https://chainz.cryptoid.info/xyz/

Service & Technology

What is required to host an Explorer here?

Note: Explorer additions are currently suspended
After a hectic early 2017, we are reaching the limits of our current infrastructure, back-office tools especially. So rather than jeopardizing stability of current explorers, we are suspending addition of new explorer for Summer 2017, and we will use that time to upgrade our back-office and automation tools.

We require a client wallet with a Bitcoin-compatible RPC API, that can be compiled from source code (preferably on github or similar) and that will run under Debian 7

We may also currently ask for a contribution to hosting costs, as servers hosting the wallet daemons are our major source of expenses.
Currently, we prefer to host the daemon ourselves for reliability reason, both so we know what code the daemon is running and to ensure good uptime.

Preferred contact method is currently through bitcointalk.

Note that due to unclear BitLicense requirements, requesting an explorer is not possible for New York state residents or citizens. If you happen to live or be a New York state citizen, please contact the NY DFS for further inquiries.

Great, what is included in an Explorer?

All Explorers come with the standard feature set:

  • One full node, with "as high as possible" connection limits
  • Rich List, wealth distritibution/li>
  • Exchange wallet detection and Large Wallets ranking
  • Public API
  • Extraction & network health stats
  • Ticker, market cap, SSL encryption, etc.
Explorers will also automatically get all future features.

Explorers and nodes are also monitored, and a backup server is maintained ready.

What technology are you using?

The explorers are built on alternative tech, not related to abe, insight or other existing explorers.

The server-side code is powered by DWScript and SQLite databases, and was initially built as a tech demonstrator.
The client-side makes use of jQuery, Bootstrap, Google Charts and jqGeoChart
Wallets are hosted on Debian 7 & Ubuntu 14 servers.
