What is ARPA Chain (ARPA)?
ARPA Chain is a layer-2 solution that focuses on security and privacy. Besides the use of already-existing security methods such as Homomorphic Encryption, Zero-Knowledge Proofs, and Trusted Execution Environments, it deploys its own Multiparty Computation (MPC) model that enables different parties to work on the same task without revealing their inputs to one another. These together with sharding allows the network to achieve both security and scalability.
ARPA Chain offers data renting and secure private smart contract services for both individuals and enterprises. Its partners include AlibabaCloud, Sinochem, JD.com, IOST, and Zhejiang University, to name a few.
How ARPA Chain (ARPA) Works
ARPA Chain consists of two layers:
- Protocol layer, where nodes contribute computational power to receive ARPA tokens, node activities are recorded, and MPC is prepared for the computation layer.
- Computation layer, where MPC is executed and data is verified.
Unlike most other networks, ARPA Chain uses three mechanisms for consensus:
- Proof of Correctness (PoC), which is a consensus mechanism quite similar to PoW. But with PoC, only a few nodes are assigned work instead of all nodes in PoW.
- Proof of Computation, which records the amount of computation completed by nodes and releases rewards accordingly.
- Proof of Secureness, which verifies off-chain computation done in Trusted Execution Environments.
How Many ARPA Chain (ARPA) Tokens Are in Circulation?
ARPA is the native governance and utility token of the ARPA chain. There are 2 billion tokens in total supply, and 1.24 billion in circulation.

Moldova, officially the Republic of Moldova, is a country in Eastern Europe. It is bordered by Ukraine to the north, east, and south and Romania to the west. Moldova covers an area of 33,851 square kilometres, with a population of around 2.6 million. Even though a landlocked country, Moldova is only three kilometres from the Black Sea at its closest point, separated only by Dniester Liman. The Danube flows very closely near Moldova’s southern border, but Moldova only has access to it for about 480 metres.
Situated at the crossroads of several distinct, influential cultures such as Latin, Slavic, and Byzantine, Moldova has drawn from them to enrich its own culture. Its cultural heritage was marked by a considerable number of churches and monasteries from the 15th century, as well as its deep influence on modern Romanian culture. Moldova and Romania share their national poet and writer, Mihai Eminescu and Ion Creangă, both considered the most influential Romanian language artists.
With Moldova’s national currency – the Moldovan leu (MDL) – you can purchase cryptos in just a few minutes, whether you’re in Chișinău, Tiraspol, or Bălți, or anywhere else in the country. Bitget employs numerous secure methods, including crypto deposits, P2P trading, and other third-party merchants, such as Apple Pay, Google Pay, and various credit cards, to offer you a wide range of payment options and solutions to meet any of your cryptocurrency needs.
