Codex Decentralized Durability Engine
The Codex project aims to create a decentralized durability engine that allows persisting data in p2p networks. In other words, it allows storing files and data with predictable durability guarantees for later retrieval.
WARNING: This project is under active development and is considered pre-alpha.
Build and Run
For detailed instructions on preparing to build nim-codex see Building Codex.
To build the project, clone it and run:
make update && make exec
The executable will be placed under the build
directory under the project root.
Run the client with:
build/codex
CLI Options
build/codex --help
Usage:
codex [OPTIONS]... command
The following options are available:
--log-level Sets the log level [=INFO].
--metrics Enable the metrics server [=false].
--metrics-address Listening address of the metrics server [=127.0.0.1].
--metrics-port Listening HTTP port of the metrics server [=8008].
-d, --data-dir The directory where codex will store configuration and data..
-i, --listen-addrs Multi Addresses to listen on [=/ip4/0.0.0.0/tcp/0].
-a, --nat IP Addresses to announce behind a NAT [=127.0.0.1].
-e, --disc-ip Discovery listen address [=0.0.0.0].
-u, --disc-port Discovery (UDP) port [=8090].
--net-privkey Source of network (secp256k1) private key file path or name [=key].
-b, --bootstrap-node Specifies one or more bootstrap nodes to use when connecting to the network..
--max-peers The maximum number of peers to connect to [=160].
--agent-string Node agent string which is used as identifier in network [=Codex].
-p, --api-port The REST Api port [=8080].
-q, --storage-quota The size of the total storage quota dedicated to the node [=8589934592].
-t, --block-ttl Default block timeout in seconds - 0 disables the ttl [=86400].
-c, --cache-size The size in MiB of the block cache, 0 disables the cache - might help on slow
hardrives [=0].
--persistence Enables persistence mechanism, requires an Ethereum node [=false].
--eth-provider The URL of the JSON-RPC API of the Ethereum node [=ws://localhost:8545].
--eth-account The Ethereum account that is used for storage contracts [=EthAddress.none].
--eth-deployment The json file describing the contract deployment [=string.none].
Available sub-commands:
codex initNode
Example: running two Codex clients
To get acquainted with Codex, consider running the manual two-client test described HERE.
Interacting with the client
The client exposes a REST API that can be used to interact with the clients. These commands could be invoked with any HTTP client, however the following endpoints assume the use of the curl
command.
/api/codex/v1/connect/{peerId}
Connect to a peer identified by its peer id. Takes an optional addrs
parameter with a list of valid multiaddresses. If addrs
is absent, the peer will be discovered over the DHT.
Example:
curl "127.0.0.1:8080/api/codex/v1/connect/<peer id>?addrs=<multiaddress>"
/api/codex/v1/download/{id}
Download data identified by a Cid
.
Example:
curl -vvv "127.0.0.1:8080/api/codex/v1/download/<Cid of the content>" --output <name of output file>
/api/codex/v1/upload
Upload a file, upon success returns the Cid
of the uploaded file.
Example:
curl -vvv -H "content-type: application/octet-stream" -H Expect: -T "<path to file>" "127.0.0.1:8080/api/codex/v1/upload" -X POST
/api/codex/v1/debug/info
Get useful node info such as its peer id, address and SPR.
Example:
curl -vvv "127.0.0.1:8080/api/codex/v1/info"
/api/codex/v1/debug/chronicles/loglevel
Set chronicles log level and topic filtering at runtime. The request format is ?level=<MAIN LEVEL>;<FILTER LEVEL>:<TOPIC>
- e.g. ?level=DEBUG;TRACE:codex
Example:
curl -X POST -H 'Content-Type: text/plain' -vvv "127.0.0.1:8080/api/codex/v1/debug/chronicles/loglevel?level=DEBUG;TRACE:codex" -d ""
