Securely Connecting to a Peer2Peer Network means you need to choose a client...

Verification DB-Size
Bandwidth MultiChain Used in
FullNode all Blockheaders and each transaction and all full state ~400GB
all devp2p-messages sync with only one chain on servers, where full access is needed
Pruned Node all Blockheaders and each transaction, but keeps the most recent state ~40GB
all devp2p-messages sync with only one chain on servers
Light Client only Blockheaders ~50MB
all blockheader and status-messages + asking for proof and state when needed sync with only one chain on any pc, laptop or at stringer IOT-Devices
Remote Client none - just trusted 0
only when asked one chain per url browser and apps on mobile devices
slock.it Client verification of single result (Merkle-Proof) based on deposit backed signed blockhash 0
only when asked connect to multiple chains browser and apps on mobile devices and even small IOT-Devices


The Client uses the Incubed-Network to connect to any chain. This Network of Remote Clients offers the features needed in order to run on small IOT-devices.


The client does not need to sync, which means you can turn on the device and start using it.

Easy Integration

The JS-Client can be used as HTTP-Provider in Web. No changes in the dapp needed.

No Single Point of Failure

Based on a Decentralized Network means zero down time.

No login

No central server. All permissions are managed by cryptographic keys.


One client can connect to any chain, where registered nodes exist. This includes any EVM-based, even private chains, but eventually also Bitcoin and more.


Each request to the network can be verified with a cryptographic proof which includes a signature of the nodes that would lead to losing its deposit of a node if this is wrong.

How does it work?

Incubed connects devices to the Blockchain in order to control access.

  • Nodes
  • Client
  • Proof
  • Watchdogs
The Incubed-Network is a decentralized permissionless network where anybody can setup a node and register this node in a smart contract, called the registry. Nodes store a deposit, which they will lose, if they sign wrong blockhashes. This will lead to more trust and more requests will lead to more payments.

Each node may register for multiple chains. The client then can simply define per request which chain should be asked.
The client acts stateless. The only information it needs to store and update is the list of nodes in the network. This list is taken from the registry contract on the blockchain.
Depending on the stored deposit of the nodes and a random seed, the client will choose one or more nodes from the list and send the json-rpc-requests.

The client itself is a very small library easily included in an IOT-device, even if this runs on very low specs. This is possible since the device only needs to be able to send HTTP-Request when needed and doesn’t synchronize each blockheader.
There are 2 versions available:
  • JS-Library, which can be fetched using npm and is included in any browser app.
  • A bare metal version written in C, ready to be included in even a microcontroller.
The client sends a JSON-RPC-Request to a randomly chosen node including an optional list of validator-nodes. The node execute the request and prepares all data needed in order to verify the result. In most cases this means
  • the full blockheader
  • in case of an eth_call, the call is analyzed and all needed values from the state are added, including the complete Merkle-Proof.
  • the signatures of all validators sign the same blocknumber and blockhash. By doing so, these validators risk their previously stored deposit in case they give a wrong hash, because these signed blockhashes can be used to convict the signer directly in the registry-contract.
The client can then verify the response by replaying this transaction in a local evm and validate all values by using the Merkle-Proofs.
Watchdogs are nodes that constantly test other nodes with requests and ask for the blockhash. If they give a false hash, they lose their deposit.
