Chisel will implement a decentralized add-only set.

It is intended to provide a censorship-resistant highly-available system for storage and retrieval of both confidential and public data.

Potential uses

• email hosting

• web publishing

• reliably logging anomalous events

• auditable distribution of software updates

Glossary

• Pool: a content-addressable data store

• Scroll: an ordered set of hashes

• ChiselSet: the decentralized writable resource. Combines a Pool, a Scroll, a write policy, and a collection of notaries

• Notary: maintains ChiselSets and services read and write operations on them

Hacking

These instructions are not entirely tested, but might get chisel running in a virtualenv. You should use virtualenv 1.9.1 or later.

virtualenv chisel
cd chisel
venv=$(pwd)
echo "export LD_LIBRARY_PATH=$venv" >> ./bin/activate
. ./bin/activate
mkdir src && cd src

tgz=$(basename $tgz_url)
curl $tgz_url > $tgz
[ "`sha256sum $tgz`" == "$h  $tgz" ] &&
tar xf libsodium-win32-0.4.2.tar.gz &&
