steemworlds.sk

Steemworlds.sk is a addon to STEEM.CRAFT which allows you to load and save worlds to the Steem Blockchain using a public Steem node without any third party service.

Usage

Advanced details

Comment storage

Comments created by the addon can be modified in the options. But the json metadata of the comments should always look similar to this:

{"app":"STEEM.CRAFT","format":"markdown","world":[{"x":-1,"z":-1,"i":1,"b":"33160294"},{"x":-1,"z":0,"i":1,"b":"33160303"},{"x":-1,"z":-1,"i":2,"b":"33160301"},{"x":0,"z":-1,"i":1,"b":"33160314"},{"x":-1,"z":0,"i":2,"b":"33160308"},{"x":0,"z":0,"i":1,"b":"33160322"},{"x":0,"z":-1,"i":2,"b":"33160316"},{"x":0,"z":0,"i":2,"b":"33160324"}]}

It contains the following data:

app	format	world
STEEM.CRAFT	markdown	[{"x":chunk x-coordinate,"z":chunk z-coordiate,"i":chunk part id,"b":"blockid"}] (this part is compressed and base64 encoded)

The world data can increase the more and bigger chunks the world has. Due to limitations, the json metadata can't be unlimited in size, this is going to limit the size of the world. Referencing all blocks is limit to a maximum of around 16kb. This is why the referencing data is compressed and stored as base64.

Custom JSON transactions

The chunks are not directly stored in the comments, the comments just store a reference to each custom JSON transaction. This allows also bigger worlds to be saved.

A custom JSON transaction from steemworlds is going to look like this:

{"w":"immanuel94","x":0,"z":0,"s":3,"i":3,"data":"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"}
