The Pascal Developers fundamentally improved the SafeBox design by providing the “missing piece of the puzzle” – the ability to make 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 Pascal V2 by Albert. In addition, nodes will be able to earn fees by offering their latent PASC and PASA for these tumbling operations whilst simultaneously providing a rich set of decentralized PASC/PASA to participate in the tumbling. This would result in a fast, cheap, seamless and genuine anonymity for Pascal users.

  1. The verification throughput of Pascal and a traditional blockchain are also similar.
  2. Unlike traditional UTXO-based cryptocurrencies, the blockchain in Pascal is only used to mutate the SafeBox.
  3. After the initial V1 release, new developers joined the project forming what is known as the Pascal Developers.
  4. The difference between the time needed to search in a saved database on disk (UTXO) versus searching in memory (SafeBox) is significant, leading to a nearly instant transaction speed in Pascal.
  5. Thanks to how the SafeBox in its entirety is stored compactly in memory, this process is almost instantaneous in Pascal.

Each block header makes a hash commitment to the previous SafeBox state (i.e. the state of all accounts at that point in time) and also the previous block header. In this manner, the state and its evolution are preserved by using the difficulties in the block headers; the total work used to evolve that state can then be calculated. This website is using a security service to protect itself from online attacks. There are several actions that could trigger this block including submitting a certain word or phrase, a SQL command or malformed data. Operations in Pascal are the equivalent to “transactions” in traditional cryptocurrencies.

• If one falls to a state-attack, the worst case is that he would simply need to re-download a longer segment of the Pascal blockchain history and recover his balance(s). The state-attacker would be stuck with invalid balances unless he continues to fool others. Since only the ledger balance is required for consensus and not the full ledger, Pascal attains exponentially higher transaction throughput per unit of storage than UTXO-based cryptocurrencies. Unlike traditional UTXO-based cryptocurrencies, the blockchain in Pascal is only used to mutate the SafeBox. Whilst a Proof-of-Work blockchain is still required to facilitate Byzantine consensus (up to a checkpoint), it is not permanently required. As a result, the blockchain in Pascal is capable of being deleted without any security compromise.

After the exchange of public keys; the new owner (with the private key) obtains full rights over the PASA, the public key and private key held by the previous owner becomes invalid as regards the sold PASA. The new owner can now use the PASA for transactions on the Pascal blockchain and can also sell-on this account or give it out when he/she wishes using the same procedure. The double spend protection mechanism entails searching a given blockchain’s database (usually based on UTXO) for whether the previous transaction has been spent or not. With the SafeBox, this process is as quick as simply viewing the signer’s account state. Thanks to how the SafeBox in its entirety is stored compactly in memory, this process is almost instantaneous in Pascal.

What is Pascal Coin?

Due to Pascal’s design, transactions to and from accounts can be easily audited by anyone. For many use cases, this is an excellent feature since it makes auditing, reconciliation and accounting very simple. However, Pascal is also committed to providing equally anonymizing features for those use cases where privacy is important. As a result, Pascal has a strong privacy roadmap that has already been partially rolled out. • The amount of difficulty required to re-mine a history grows exponentially. This means it’s exponentially harder to re-mine the last 3 blocks than it is the last 2, and so on.

For example, the default setting for nodes who opt for checkpointing instead of continuous history is to download a checkpoint per 2016 blocks or 7 days. As another example, one upcoming implementation involves downloading a checkpoint and then some preceding history; if invalid blocks are found in history, then the compromised checkpoint is eschewed altogether. A distinction should be made between cryptographic integrity, the proof that the SafeBox is hashed correctly from block 0, and cryptographic security, the number of blocks that need to be re-mined in an attack.

Every time a new block is minted, the transactions or operations contained within that block are eventually applied to the SafeBox which results in a mutated state. The resultant hash of the mutated SafeBox must then be referenced by the subsequent block in order to qualify as the next block. Secondly, Pascal solves the long-term blockchain “storage issue” by introducing deletable blockchain technology. This technology allows Pascal nodes to securely delete the blockchain beyond the last 100 blocks. It should be emphasized that Pascal’s blockchain throughput is technically unbounded.

The difference is that Pascal has many different types of operations, not just for transferring funds. For example, there are operations to change an account’s key or to change an account’s name. As a result, an operation in Pascal should be considered as an abstract and generalised form of a cryptocurrency “transaction”.

Technically, no blockchain data in Pascal is ever deleted even in the presence of the SafeBox. Since the SafeBox is cryptographically equivalent to a node with the entire history, Pascal nodes are not expected to contain infinite history. But for any reason(s) one may have, one could still keep all or some of the Pascal blockchain history as an option. If a state-attacker naively alters an account balance then it becomes corrupt since the tip block has an invalid SafeBox hash. Pascal is a fast, zero-fee, scalable and totally decentralized multi-purpose blockchain designed for payments, data operations and layer-2 applications.

Horizontal scaling also exists in this paradigm as there is no interdependence between smart contracts and states are not managed by side-chains. One would be able to run the entire global financial system on Pascal’s smart contract platform and it would scale infinitely and securely. The maximum block size of 5.62 GB is assumed and the average operation size is 262 bytes. The expression is then divided by 300, the number of seconds in a 5-minute block. The SafeBox security model actually offers an advantage compared to the full blockchain model in terms of security because it places far less dependence on the full blockchain history (i.e. archival nodes).

Implementing this infinitely scalable smart contract platform as a Layer-2 architecture is the focus of version 5 and a whitepaper add-on for this development will be released shortly. • Running a smart contract engine like the Ethereum Virtual Machine (EVM) over Pascal would be possible by maintaining a side-chain pinned to a PASA account. Each PASA has infinite address space for its sub-addresses (unlike PASAs, infinite sub-addresses do not affect the SafeBox), meaning that side-chain users do not need to own a PASA.

This would translate in many more users trying to sell their dormant, inactive PASAs. • The total maximum number of possible PASAs in existence is 4.2 billion, and this could easily be pascal coin value increased if needed. With a layer-2 implementation, Pascal’s scalability will be enhanced even further. More information on Pascal’s layer-2 specifications will be released shortly.
