451PCBcom (PCB) whitepaper v2.1 released.

2 min readDec 10, 2021


451PCBcom (PCB) is a TRC-20 token created on the TRON blockchain by our non-profit association to promote, develop, make, reward, share and exchange open source hardware.

The PCB token is not an simple speculative token, it has a lot of utility functions in the real world for the members of our open source hardware community of supporters.

TRC-20 is the basic code standard for a token in the TRON blockchain to implement some minimal token functions using a smart contract. So PCB token is a coupon, similar to a privately issued digital currency, which is the unit of value that the association creates to self-govern, and empower open source hardware users to interact with us, facilitating the open source hardware exchange, share and distribution, with rewards, utility and benefits to all the token holders.

The PCB token is distributed to our association members to use it as a tool to exchange open source hardware, rank and reward the community who support open source hardware and promote it in collaboration with us. It is utilized to obtain some external services necessary for the project development too.

When you hold PCB tokens, you are a member of our community of supporters, so you are collaborating to develop and make open source hardware, empowering our community to do it. Your support reputation rank depends on how many PCB tokens you hold.

When we send rewards to our community it is based on their PCB holder rank, knowledge and collaboration to make and promote open source hardware, and never by lucky or competitive games.

We don’t know any other project of a tokenized open source hardware design at this moment. We will be happy to know about other open source hardware makers with blockchain projects.

The future and our community is open. Join us.
