PART is the cryptocurrency designed to be the heart of the Particl ecosystem and acts as the fuel that makes it run

It’s a technically advanced privacy coin, a voting ticket, a moderation token, a source of passive income, and much more. It is multi-purpose.

Yes, PART is officially supported by Ledger wallet with cold staking capabilities enabled. You can set up your hardware Particl wallet and start safely earning staking rewards.

Particl is also currently working on a Trezor integration.

The Particl team is in constant discussion with many exchanges, however, the decision to list PART or not is entirely up to the exchanges themselves.

PART is built on the Bitcoin Core codebase and is always kept up-to-date with Bitcoin's latest version within days. Updating the codebase to the most recent version allows the platform to benefit from the latest security, performance and stability development made on the Bitcoin Core codebase as well as stay compatible and easy to integrate with the ever-evolving Bitcoin ecosystem.

The default fee for public transactions is 0.002 PART per kb but you can adjust the limit to your needs (higher fee = better confirmation times).

Privacy transactions (RingCT + Bulletproofs) default to around 0.005 PART per transaction, although that fee varies depending on the number of ring signatures (degree of privacy) used by the user when making a transaction.

Size Without Segwit & Bulletproofs With Segwit With Bulletproofs
Public 255 B 202 B -
Confidential Transaction (CT) 5,485 B 2,865 B ~1,706 B
RingCT (4 ring members) 5,723 B 3,009 B ~1,949 B

Annual inflation of PART tokens is 4% up until the 17th of July 2019, and then drops 1% each year until it levels out at 2%.

Period Staking rewards / inflation rate
July 2017 – July 2018 5 %
July 2018 – July 2019 4 %
July 2019 – July 2020 3 %
July 2020 onwards 2 %

  • Freedom of choice.
  • To keep the process of coin minting transparent and have a fully auditable supply. If a bug or exploit were to occur at the staking level, it would be instantly detected whereas with a 100% private chain, it could go unnoticed for an extended period of time.
  • To raise the probability and lower the technical barrier to get adopted by third-party services (easier to integrate).
  • As fees are higher for privacy transactions, some users might not want to execute private transactions if they do not require it.

While there is currently no whitepaper available as it relates to our own integration onto the Bitcoin Core codebase, there are whitepapers available for the original privacy protocols themselves:

Particl is natively integrated with Segwit, meaning it has been activated since Block 1 and is enabled by default on all transactions. It is not possible to make non-Segwit transactions on Particl.

Atomic swaps are decentralized and trustless trade between two users of different cryptocurrencies. It makes trading cryptocurrencies without any third-party (i.e. trading exchange) and have blockchains directly interact between each other (i.e. cross-chain smart-contracts) possible.

Calculating this metric is pretty hard as greatly depends on the ratio of public, blinded and anonymous transactions. Several other factors can impact the results such as smart-contracts and multisig address transactions.

In the end, a more accurate metric would be to calculate each transaction size. Regardless, it is still possible to calculate a very approximative estimate of Particl's TPS by assuming all transactions are either public or private, and by disregarding smart-contracts and multi-signatures. In reality, this metric is pretty innacurate, but interesting nonetheless if only to observe the purely coin-related theoretical performance of the blockchain:

Bitcoin Particl
Block Size 1 MB 2 MB
Block Time 10 min 2 min
TPS (100% public transactions) ~7 (no Segwit) ~85 (Default Segwit)
TPS (100% RingCT transactions) - ~8.80 (Default Segwit + Bulletproofs)

(The RingCT is calculated with 4 ring members)
