A completely original cryptocurrency with groundbreaking new technology called Safebox

PascalCoin is an innovative cryptocurrency that extends the blockchain-paradigm

Based on a groundbreaking and unique new idea in crypto, PascalCoin pioneers a new tier of scalability suitable for planetary-scale adoption. It is the first and only cryptocurrency to have broken the 100 transactions per second barrier!

By offering simple account numbers that can be associated to emails, company names and domain names, payments have never been easier.

PascalCoin’s powerful architecture lays the strong foundation for large-scale smart contracts in the form of Layer-2 protocols.

PascalCoin achieves all this by introducing a new cryptographic data-structure known as the SafeBox. The SafeBox compliments the Blockchain in a way that allows the Blockchain to be deleted whilst retaining its full cryptographic security.

Frequently Asked Questions

  • The SafeBox is composed of many account segments
  • Each account segment contains a set of N accounts (N is 5 for now)
  • Each account contains a user’s public key, current balance, etc
  • Blocks are mined using Proof-of-Work, with 5 minutes confirmation time
  • Every new block appends an account segment to the SafeBox
    • These accounts are awarded to the miner
    • 1 of these accounts contains the mining reward with PASC
    • Copy of the block header is kept in the account segment (V2)
  • Blocks contain signed transactions (operations) which update balances/keys of existing accounts
  • New blocks reference the hash of the SafeBox, not last the block.
  • Only 100 blocks are kept for difficulty calculation, rest can be deleted freely.
  • Nodes process and update their SafeBox’s independently, ensuring P2P decentralisation
    • Nodes only accept the SafeBox with “most-work”. The work for each block is determined from the proof-of-work payloads inside the block headers maintained in account segments.
  • Nodes distribute SafeBox’s to themselves in a torrent-like manner

PascalCoin uses 5 minute block-time. However, 0-confirmation transactions are more reliable than in other cryptocurrencies. Additionally, once the double-spend-detection-serivice is rolled out, merchants will be able to accept 0-confirmation transactions with high degree of confidence, suitable for small purchases like Coffee.

For transactions of significant value, we commend a reasonable number of confirmations before considering payment as cleared.

PascalCoin is Proof-of-Work (PoW).

The SafeBox model does not work with Proof-of-Stake (PoS) since stake-proofs cannot be aggregated to secure the SafeBox..

PascalCoin is currently as anonymous as Bitcoin. Whilst accounts and balances are publicly visible, the knowledge of who controls those accounts is not.

PascalCoin does provide an extra level of anonymity through PASA Exchange. Instead of Bob paying Alice 100 PASC, Bob transfers an account containing 100 PASC to Alice. So long as Alice uses a new key and communicates that key to Bob through secure channels, there is no way to link Bob and Alice.

In the Roadmap, there are plans to add Private Balances and Private Payments into PascalCoin using the ZK-SNARKs approach pioneered by ZCash. This will provide comprehensive anonymity. Receiver will not know who sender is, and 3rd parties will not know sender, receiver or amount being sent. Public balances and public transactions will be retained as it is useful for many use-cases.

PascalCoin was invented and designed by Albert Molina in May 2016. By July 2016, the the first beta version was released. On August 11, 2016, the PascalCoin genesis block was generated and Albert published the source code and wallet installer on GitHub and SourceForge, and explained it at Bitcoin freenode forum. A few hours later he started a thread at BitCoinTalk explaining it.

After the initial V1 release, new developers joined the project forming what is known as the PascalCoin Developers. The PascalCoin Developers fundamentally improved the SafeBox design by providing the “missing piece of the puzzle” – the ability of making the SafeBox independently verifiable without the need for blocks, even for new nodes. This innovation was initially proposed by Herman Schoenfeld, and after discussion with Albert, was implemented in PascalCoin V2 by Albert.

PascalCoin Improvement Proposals (PIPs) are the standard way for changes to be introduced into PascalCoin. PIPs are intended to be the primary mechanisms for proposing new features into PascalCoin and documenting design decisions. Anyone can submit a PIP and all PIPs are evaluated through the PIP Workflow. Click here to see the current list of PIPs.

Development is organised via the Trello board using Agile development methodology. PascalCoin currently has several full-time developers including Albert Molina and Herman Schoenfeld. Sphere 10, a company directed by Herman, also allocates developers to this project from time to time. Currently there are 5 full-time developers actively working on PascalCoin. PascalCoin also has a growing community of infrastructure developers including Jason Knapp, developer of PascWallet.com PASA exchange. Various other developers have contributed to the PascalCoin project (web, documentation, code, etc).

Operations in PascalCoin are the equivalent to “transactions” in traditional cryptocurrencies. The difference is that PascalCoin has many different types of operations, not just for transferring funds. For example, there are operations to change an accounts key or to change an accounts name. As a result, an operation in PascalCoin should be considered as an abstracted and generalised form of a cryptocurrency “transaction”.

A “Transaction” in PascalCoin is a type of Operation that transfers funds between accounts.

PascalCoin currently supports the following operations:

  • Transaction: moves funds from one account to another
  • Change Account Key:changes owner of an account
  • List Account For Sale: lists account for public or private sale
  • Delist account:delists an account from sale
  • Buy Account: purchase & settlement for an account listed for sale
  • Change Info: changes an account name and type
  • Recover Account: reap zombie account to a new owner (account must not have made an operation for at least 4 years)

When operations are sent, they are visible to all nodes after a few seconds. However, they live in the “Pending Operations” pool until a miner mints them in a block. After 5 minutes (average), a block will be minted and will likely contain all the Pending Operations. As with other blockchain-based cryptocurrencies, it is best to wait a reasonable number of block confirmations before considering the payment as cleared. The more block confirmations that operation receives, the less likely it is ever to be rolled back.

For large transfers, waiting for 2-4 confirmations is acceptable. For small micro-transactions, many accept 0-confirmation transaction since they are still quite safe. In future, there will be a Double-Spend-Detection-Service to further verify 0-confirmation transactions for reliability. Good enough for Coffee.

PascalCoin can be purchased from cryptocurrency exchanges using Bitcoin and/or other major coins.

See next question for list of exchanges.

There are many options to mine PacalCoin from solo-mining to pool-mining. Check out this mining guide.

Visit our Discord channel #mining and discuss with community to get started.

How to Dual Mine ETH and PASC using Coinotron

  • Create account at Coinotron
  • Click activation link in your mail
  • Login
  • Create a worker under “My Account” > “Workers”
  • Download Claymore Dual Miner from bitcointalk.
  • Add “-dcoin pasc -dpool coinotron.com:3348 -dwal username.workername” to your start.bat where username is your Coinotron username, and workername is the name of the worker you created in step 4.

Do you still have questions? Take a look at the long, thorough PDF guide.

Source code is maintained in GitHub.

PascalCoin offers a JSON RPC API available on both the Daemon and the GUI.

There is a full C# implementation of PascalCoin being developed by Sphere 10 Software called NPascalCoin. It currently supports the JSON-RPC API with plans for network protocol.

Proof Of Work Summary

Proof of Work = SHA256(SHA256(WorkPayload))

WorkPayload := Digest1 ++ Digest2 ++ Digest3

Digest1 := BlockNumber ++ AccountKey ++ Reward ++ ProtocolVersion ++ ProtocolAvailable ++ CompactTarget

Digest2 := miner payload (raw bytes, ASCII string used as convention)

Digest3 := CurrentSafeBoxHash ++ OperationsHash ++ Fee

The OperationsHash is similar in concept to the merkle-root of transactions except is calculated as follows:

OperationsHash := OperationHash(N) where N is number of operations in the block where

OperationHash(x) := SHA256(OperationHash(x-1) ++ Operation[x].Hash)
