+# Decentralization
+
+In the default setup, the ZKsync node will fetch data from the ZKsync API endpoint maintained by Matter Labs. To reduce
+the reliance on this centralized endpoint we have developed a decentralized p2p networking stack (aka gossipnet) which
+will eventually be used instead of ZKsync API for synchronizing data.
+
+On the gossipnet, the data integrity will be protected by the BFT (byzantine fault-tolerant) consensus algorithm
+(currently data is signed just by the main node though).
+
+## Enabling gossipnet on your node
+
+> [!NOTE]
+>
+> Because the data transmitted over the gossipnet is signed by the main node (and eventually by the consensus quorum),
+> the signatures need to be backfilled to the node's local storage the first time you switch from centralized (ZKsync
+> API based) synchronization to the decentralized (gossipnet based) synchronization (this is a one-time thing). With the
+> current implementation it may take a couple of hours and gets faster the more nodes you add to the
+> `gossip_static_outbound` list (see below). We are working to remove this inconvenience.
+
+> [!NOTE]
+>
+> The minimal supported server version for this is
+> [24.11.0](https://github.com/matter-labs/zksync-era/releases/tag/core-v24.11.0)
+
+### Generating secrets
+
+Each participant node of the gossipnet has to have an identity (a public/secret key pair). When running your node for
+the first time, generate the secrets by running:
+
+```
+docker run --entrypoint /usr/bin/zksync_external_node "matterlabs/external-node:2.0-v24.12.0" generate-secrets > consensus_secrets.yaml
+chmod 600 consensus_secrets.yaml
+```
+
+> [!NOTE]
+>
+> NEVER reveal the secret keys used by your node. Otherwise, someone can impersonate your node on the gossipnet. If you
+> suspect that your secret key has been leaked, you can generate fresh keys using the same tool.
+>
+> If you want someone else to connect to your node, give them your PUBLIC key instead. Both public and secret keys are
+> present in the `consensus_secrets.yaml` (public keys are in comments).
+
+### Preparing configuration file
+
+Copy the template of the consensus configuration file (for
+[mainnet](https://github.com/matter-labs/zksync-era/blob/main/docs/guides/external-node/prepared_configs/mainnet_consensus_config.yaml)
+or
+[testnet](https://github.com/matter-labs/zksync-era/blob/main/docs/guides/external-node/prepared_configs/testnet_consensus_config.yaml)
+).
+
+> [!NOTE]
+>
+> You need to fill in the `public_addr` field. This is the address that will (not implemented yet) be advertised over
+> gossipnet to other nodes, so that they can establish connections to your node. If you don't want to expose your node
+> to the public internet, you can use IP in your local network.
+
+Currently the config contains the following fields (refer to config
+[schema](https://github.com/matter-labs/zksync-era/blob/990676c5f84afd2ff8cd337f495c82e8d1f305a4/core/lib/protobuf_config/src/proto/core/consensus.proto#L66)
+for more details):
+
+- `server_addr` - local TCP socket address that the node should listen on for incoming connections. Note that this is an
+  additional TCP port that will be opened by the node.
+- `public_addr` - the public address of your node that will be advertised over the gossipnet.
+- `max_payload_size` - limit (in bytes) on the sized of the ZKsync ERA block received from the gossipnet. This protects
+  your node from getting DoS`ed by too large network messages. Use the value from the template.
+- `gossip_dynamic_inbound_limit` - maximal number of unauthenticated concurrent inbound connections that can be
+  established to your node. This is a DDoS protection measure.
+- `gossip_static_outbound` - list of trusted peers that your node should always try to connect to. The template contains
+  the nodes maintained by Matterlabs, but you can add more if you know any. Note that the list contains both the network
+  address AND the public key of the node - this prevents spoofing attacks.
+
+### Setting environment variables
+
+Uncomment (or add) the following lines in your `.env` config:
+
+```
+EN_CONSENSUS_CONFIG_PATH=...
+EN_CONSENSUS_SECRETS_PATH=...
+```
+
+These variables should point to your consensus config and secrets files that we have just created. Tweak the paths to
+the files if you have placed them differently.
+
+### Add `--enable-consensus` flag to your entry point command
+
+For the consensus configuration to take effect you have to add `--enable-consensus` flag to the command line when
+running the node, for example:
+
+```
+docker run "matterlabs/external-node:2.0-v24.12.0" <all the other flags> --enable-consensus
+```
