For more complex projects I'd probably run a node myself, but I'll still keep an eye on this thread to see how it evolves.

FYI:

Code:

{"method": "getlatestblock"}

returns invalid JSON Lips sealed

Code:

{u'merkleroot': u'ae60086ad3d9d53c3213a271c1117449f77f70d89ff7536beb194b5009a12543', u'nonce': 1580982470, [...]

(eg. u'merkleroot' should be "merkleroot")

Thanks for notifying me... It's indeed an invalid json, i'll fix it tomorrow morning

EDIT: had some time, fixed it right away! Thanks for the heads up!
BTW: it's perfectly normal to use your own node, even for smaller projects. As a matter of fact, i'd encourage anybody to use their own node. Using my service requires trust... I could easily modify the respons i send to any query, my node can lag, my node can be the victim of an attack...
That being said: i don't offer wallet services, you can't create desposit addresses, sign transactions,... By keeping these sensitive services away, i kind of mitigate the problem (afaik).

This service is just an easy sollution for anybody who wants medium-complex core functions without running core, probably even from a shared server without any functionality (you can create static pages and use javascript to communicate with an open socket, thus add dynamic functionality without any server side scripts).

What stack are your WS implementation ? Do you need help with development ?

I'm actually using websocketd (http://websocketd.com/), so the language of the script itself doesn't really matter Wink

Thanks for your offer to help with the development, but at the moment i can handle it... I'm just gauging intrest to see if i'll only develop the functions i need for myself or if i need to develop the full range of functions.

I'm currently developing websocket access to some of the functions of my full node. For a small fee, a developer, site owner or private person could use a secure websocket connection to execute most of the not-wallet-related node functions. This way, he or she get access to some core functionality without having to maintain a full node, he or she can even use javascript to include functionality on webpages on very limited shared hosting formulas.

In the beginning, i was thinking about creating such a websocket daemon for private use and throw away most of the outdated code on mocacinno.com and use a websocket connection instead... However, i tought by myself: maybe somebody else would be interested in such a websocket connection to?

Without further comments, here's a dev console view of the initial test of my websocket daemon... Be advised, only a very small part of the functionality i want to include is currently included:

https://193.70.78.148:9090/node

~~You'll need a private key in order to complete the handshake and testdrive the websocket... If you're interested in testing it out, send me a PM and i'll give you a testkey~~
I've modified my code for now, anybody connected is now automatically authenticated for the time being

Currently implemented
Authentication to the websocket:

Starting the authentication process
Completing the authentication process
Querying the authentication status

Blockchain queries:

Query the current best block hash
Find a block using a blockhash
Get the latest block
Get blockchain info
Get the current block count
Query the blockhash for height x

Todo
Blockchain queries:

get getblockheader for blockhash
get chaintxstats
get current difficulty
get all the mempool info for a certain tx (ancestors, descendants, entry)
list all tx's in the mempool

Mining:

get block template (for whatever you'd use it)
get mining info
get network hash ps
submit block

Network:

get connection count
get net totals
get network info

Raw transactions:

decode raw transaction
decode script
get raw transaction
send raw transaction

Util:

estimate fee
estimate smart fee
validate address
verify message

Custom:

analyse unconfirmed transaction
Have a timestamped message signed by me (an independant partie)
Calculate optimal fee at this point in time
