Blue Helix is dedicated to provide the secure custody and clearing platform for digital assets with high performance. Throughout the history of finance and trading market, custodian and clearing services play the fundamental role in supplying more and more trustable and tradable assets. Our goal is to become the fundamental player who provide such services that match the finance and regulation requirements in cryptocurrency world. In Blockchain technology, We believe in code rather than human.

The mission in Bluehelix is to bring safety and trust into digital asset market. Therefore, our top priority is always SAFETY and TRUST. Such priority can be found from our key concepts. As illustrated as follows, the fundamental module is the decentralized key management which employs state-of-art multi-signature technology to securely store and manage private keys that hold the digital assets. It is the key to the safety and trust of Bluehelix. On top of that, we build secure custody module, and high-performing clearing/settlement module.


The security guideline of Bluehelix is defined as:

Not a single party or minority of parties can manipulate users' digital assets

To depict this guideline, people can image that in Bluehelix network, we bring onboard all kinds of institutions, companies, projects, and funds to become our nodes. The guideline ensure that not a single malicious node, or less than 1/3 malicious nodes can trade, transfer, or manipulate any user's digital assets without the owners' consent.


Here we deep dive a bit into our decentralized key management to see how it can achieve our mission of safety and trust. The following figure gives a visualization of a general decentralized key management task. To manage keys and the assets associated to addresses, there are two common tasks: key generation and sign. In our scenario, the tasks become 

  • Decentralized key generation: multiple block producers (BP) generate a decentralized key together but without knowing each other's private key share, and the final private key, but the final public key and address is known to public.

  • Decentralized signature: multiple block producers (BP) sign a transaction using the decentralized private key without leaking its or each other's private key share's information.


Both tasks can be divided into 3 steps in computation. The above figure takes 3 block producers as example, but in practice the number of BP can be much larger.

  1. In the first step, all BP either generate or load data from their private data store, for example, their own private key shares.

  2. In the second step, all BP mutually comminucate and/or broadcast to perform secure multi-party computation (MPC).

  3. In the third and final step, all BP verifies the computation results. For example, they verifiy their own calulation of final public key is identical in key generation tasks, or they verify the signature against the public key in key sign tasks. Finally they produce multi-sign addresses and signed transaction results in key generation and sign tasks respectively.

With the secure decentralized key management, the Bluehelix platform that carries Bluehelix technology builds a decentralized custody with safety and trust. As shown below, all Bluehelix block producers (BHBP, 5 in the example below) store their private key shares for all supported blockchain digital assets. The platform acts as a cross-chain layer 2 custody solution to other blockchains including Bitcoin, Ethereum, EOS, etc. Whenever there is an asset transfer request on these blockchains, all BP will sign together the transaction, providing a secure and high efficient cross chain solution.
