PengolinCoin v3

PengolinCoin Core version v3.0.0 is now available from Github
This is a new major version release, including various bug fixes and performance improvements, as well as updated translations. Please report bugs using the issue tracker at Github

Staking note
You should only upgrade your wallet after near 700,001 block height. If you upgrade before 700,001 you may have no more staking rewards.
The SPORK_15_NEW_PROTOCOL_ENFORCEMENT_2 spork will be activated at near 700,001 block. After enabling the spork, v2.0 wallet will be disconnected from the blockchain. So v3.0 upgrade is necessary for everyone.

Mandatory Update

PengolinCoin Core v3.0.0 is a mandatory update for all users. This release contains a protocol upgrade (to 30101), new consensus rules and improvements that are not backwards compatible with older versions. Users will need to update their clients before enforcement of this update goes into effect.

Update enforcement is currently scheduled to go into effect at the following block height 700,001

Masternodes will need to be restarted once both the masternode daemon and the controller wallet have been upgraded.

Note 1: In preparation for the enforcement, upgraded peers will start rejecting non-upgraded peers few hours before the enforcement block height, we recommend everyone to be updated at max a day before the final time.

Please read the full V3 documentation on Github.

More details...

PengolinCoin 3.0 will now not only provide secure, inexpensive, and fast transactions, but it will also offer users the option to make their transactions and balances completely private or shielded.
Private or shielded transactions are accomplished through PengolinCoin’s zk-SNARKs and Sapling Privacy Protocols. The acronym zk-SNARK stands for “Zero-Knowledge Succinct Non-Interactive Argument of Knowledge.” A user can prove possession of certain information, for example, a secret key, without revealing that information and without any interaction between the prover and verifier.
The Sapling Protocol uses zk-SNARKs proofs to allow both shielded and unshielded transactions on the blockchain. This is accomplished by utilizing a Spending Key and a Viewing Key. The spending key is synonymous with a private or secret key. The Viewing Key is what is called a user’s public key. The holder of this key can view sent and received transactions. A single Viewing Key enables a user to create new addresses that aren’t related to the ones before it, thereby maintaining privacy of the user.
A user can choose to make a transaction public to public (transparent to transparent), public to private (transparent to shielded), private to public (shielded to transparent), or private to private (shielded to shielded). Transparent transactions (addresses and amounts) are completely public on the blockchain. Private transactions can’t be viewed by the public eye, but the transaction can still be verified on the PengolinCoin blockchain.

The PengolinCoin block rewards will also change. The new block rewards will be 60% for masternode holders and 40% for hot stakers. The developer fee of 5% has been removed. Masternodes are very important for blockchain validation, and transaction speed. Also, masternodes enhance the functionality and security of the PengolinCoin blockchain. We hope this will incentivize users to accumulate and, in the end, increase the number of PengolinCoin masternodes.
The cold staking feature will undergo further testing and will not be activated right away.

PengolinCoin already offers Proof of Stake, fast, inexpensive, and secure transactions. But now, PengolinCoin will offer private/shielded transactions. Privacy is a right and these are all important features for PengolinCoin users to have in today’s intrusive world.
