History and Team

In 2018, Marvin Tong and Hang Yin founded the Phala Network, marking a significant juncture in the blockchain realm. Tong, with his extensive background as a senior product manager at industry giants Tencent and Didi, and Yin, known for his pivotal role in developing Bitcoin Gold and his decade-long programming expertise, brought a wealth of knowledge and innovation to the table.

The journey of Phala began to materialize with the launch of its first testnet, PoC-1, in March 2020. This initial phase enabled the issuance and transfer of confidential tokens, showcasing the network’s potential. Progressing to July 2020, Phala introduced PoC-2, the second testnet phase, which set the stage for Vendetta, or PoC-3. This phase was notable for its integration of decentralized TEE nodes, paving the way for the ultimate launch of Phala’s mainnet as a parachain within the Polkadot ecosystem.

As 2020 came to a close, Phala Network successfully secured over $10 million in funding, with contributions from notable entities such as Candaq Group, InfiChain, Blue Mountain Labs, Incuba Alpha Group, and Exoplanet Capital. This financial endorsement not only validated the network’s potential but also positioned Phala as a formidable player in the evolving landscape of blockchain technology.

How Does Phala Network Work?

Phala Network harnesses the power of Trusted Execution Environment (TEE) technology to revolutionize the way smart contracts operate, ensuring unparalleled privacy and security. TEE, a sophisticated feature embedded in modern CPUs, provides a secure enclave for data processing, safeguarding sensitive information from potential breaches.

For instance, Intel’s CPUs incorporate the Intel SGX solution, an embodiment of TEE that offers a fortified execution space within the processor. Similarly, AMD’s SVE and ARM’s Trusted Zone are counterparts in their respective ecosystems, extending this secure functionality to a wider range of devices, including smartphones.

Through these technological innovations, Phala Network establishes a fortified execution realm for smart contracts. This is not just about preventing information leakage; it’s about creating a foundation of trust and security in the digital landscape. By integrating these secure elements into its blockchain architecture, Phala Network sets a new standard for privacy and reliability in the world of smart contracts.

Roles in the Network

Within the Phala Network, a structured protocol delineates distinct roles, each pivotal to the ecosystem’s functionality:

1. Users are the linchpin, engaging directly with smart contracts to invoke, query, and deploy them. Their interaction is facilitated through blockchain and worker nodes, with the capability to authenticate data and cryptographic proofs via either a thin client or a full node. Remarkably, this interaction doesn’t necessitate specialized hardware, as it’s compatible with most modern CPUs (from 2015 onwards).

2. Worker Nodes are tasked with executing confidential contracts within TEE-compliant hardware, operating predominantly off-chain. Each node harbors a unique program, pRuntime, within the TEE’s secure enclave, ensuring the execution’s integrity.

  • The Genesis Node is the inaugural node that orchestrates network initialization and cryptographic configurations. Singular in existence, it’s decommissioned post the network’s initiation.
  • Gatekeepers are the custodians of network secrets, pivotal for maintaining operational continuity and security. Their election is dynamic, predicated on blockchain consensus and necessitating a stake within the network. Their role is rewarded for uptime and penalized for malfeasance to ensure a consistent number of operational gatekeepers.
  • Miners provide computational resources, executing confidential contracts. They’re compensated for their contributions, with entry and exit from the network at their discretion. Miners are required to stake a modest amount of Phala tokens proportional to the CPU cores they employ for mining.

3. Remote Attestation Service stands as a verifier, ensuring the accurate deployment of pRuntime on worker nodes. Its cryptographic validations affirm that outputs are genuinely derived from TEE-executed pRuntime.

4. Blockchain, the cornerstone of Phala Network, chronicles worker node identities, smart contracts, and the state of encrypted contracts, alongside user and inter-blockchain transactions. Its integration with a Polkadot parachain slot facilitates seamless interoperability across diverse blockchains within the Polkadot ecosystem.

What is PHA Token?

The intrinsic value of PHA, the core utility token of Phala Network, is rooted in its integral role within the network’s cloud-based economy. With a finite issuance capped at 1 billion tokens, PHA is pivotal for both securing the network and facilitating its governance processes.

Participants across the spectrum, from external blockchains augmenting their capabilities to individuals seeking private data storage, leverage PHA to access the network’s computing resources and services. This token economy not only incentivizes the provision of resources but also ensures the network’s robustness and security through remuneration in PHA.

Moreover, key network participants like gatekeeper and miner nodes engage in staking their PHA as a commitment to their roles. This staking mechanism serves as a safeguard, imposing penalties through slashing of the staked PHA for any nefarious activities. Beyond this, holding PHA empowers individuals to be active participants in the network’s governance, granting them the right to vote on proposed modifications within the Phala ecosystem. Thus, PHA is not just a currency within the Phala Network; it’s a fundamental element that underpins the network’s operational integrity, governance, and community engagement.
