|
|
|
- - Third party apps/implementations of hard coded operations need to pay attention of an extra byte added on each operation using Payload
|
|
|
- - TODO: Explain "in core" changes
|
|
|
-- Partial implementation of PIP-0012 (Recover Accounts option after 4 years) -> https://github.com/PascalCoin/PascalCoin/blob/master/PIP/PIP-0012.md
|
|
|
- - Accounts updated counter will only update when executing operations in active mode (sender or signer)

|
|
-### Build 3.0.0 - 2018-05-02
|
|
|

|
|
|
- - New target calc on protocol V3 in order to reduce the sinusoidal effect
|
|
|
- - Harmonization of the sinusoidal effect modifying the rise / fall by 50% calculating over the last 10 blocks only when increase/decrease is high
|
|
|
-- New Safebox Snapshoting
|
|
|
- - This allow quickly rollback/commit directly to Safebox instead of create a separate Safebox on memory (read from disk... use more ram...)
|
|
|
- - Is usefull when detecting posible orphan blocks in order to check which chain is the highest chain without duplicating a safebox to compare
|
|
|
-- New Node network operations
|
|
|

|
|
|
- - This call will allow a simple third party app communicate directly to a node to get account info (balance, n_operation, name, public key... )
|
|
|
- - Reserverd codes from $1000 to $1FFF
|
|
|
- - A node will not break connection if those codes are used, but will response with ERRORCODE_NOT_IMPLEMENTED ($00FF)

|
|
|
- - OpHash of a multioperation will allow to include n_operation and account of each signer account, but md160hash chunk will be the same for all
|
|
|
-- JSON-RPC changes:
|
|
|
- - Added param "startblock" to "getaccountoperations" in order to start searching backwards on a specific block. Note: Balance will not be returned on each operation due cannot be calculated. Default value "0" means start searching on current block as usual
|
|
|
- - Operation Object changes:
|

- - Anti-spam measures
|
|
|
- - New Consensus Rule: A block can only contain 1 zero fee operation per sender account. If a sender account issues 2 or more zero-fee operations, that block is invalid.
|
|
|
- - SafeBox now stored in chunks to facilitate checkpoint distribution
|
|
|
- - Reintroduce orphan blocks operations on main blockchain
|
|
|
- - Added Checkpointing:

|
|
|
- - All changes are backwards-compatible for current 3rd-party infrastructure providers (exchanges, wallets).
|
|
|
- - However, use of param "ophash" has been changed in V2, see "Operation Object changes" section to know how to use "old_ophash" param value
|
|
|
- - JSON changes:
|
|
|
- - Account Object changes:
|
|
|
- - Added param "state" (values can be "normal" or "listed". When listed then account is for sale)

|
|
- - New param "signer_account" : Will return the account that signed (and payed fee) for this operation
|
|
|
- - Param "enc_pubkey": Will return both change key and the private sale public key value
|
|
|

|
|
|
- - Due to changed "ophash" param value calculation, method "findoperation" will find old "ophash" values too

- - Note: High depth search is slow because it search always starting from current state, going backwards, in order to return past balance. This can be a slow method on some account with high transactions volume.

-### Build 1.5.4.0 - 2017-03-14
|
|
|
|
|
|
-- Added Network Timestamp Adjustment (NAT) to calc valid timestamps
|
|
|
- - Minimum 4 active connections to calc median used for NAT, otherwise use local timestamp
|
|
|
- - Based on IP's (to prevent a malicious IP timejacking, each IP is only used once)
|
|
|
- - Removed IP's and recalculated after disconnecting (to prevent malicious node connecting/disconnecting for timejacking)
|
|
|
-- New blocks will not be accepted if using future timestamp greater than NAT timestamp + 15 seconds (also, mantaining current protocol rule >= lastBlock.timestamp)
|
|
|
-- Network protocol fixed to 5-5 (Nodes with version prior to 1.5 will not be allowed)
|
|
|
-- Added protection for non included operations on a block, to prevent continuous sending. Only will resend operations once.
|
|
|
-- Bug #27 fixed: Invalid timestamp on FPC (https://github.com/PascalCoin/PascalCoin/issues/27)
|
|
|
-- JSON-RPC
|
|
|
- - Method "getconnections" added "timediff" to know timestamp diff of node
|
|
|
- - Method "payloaddecrypt" added "unenc_hexpayload" result value with HEXASTRING of unencrypted payload
|
|
|
-- Fixed some "Random Memory access violation errors" bugs found caused by multithreading and disconnected nodes

|
|
|
+Please use at your own risk.
|
|
|
|
|
|
-- Fixed issue #23: RPC findoperation fails to find operation by opHash
|
|
|
-- Miners best practices: Sending new job with new timestamp every 30 seconds
|
|
|
-- Buffering last 10 sent jobs to miners
|
|
|
-- Small delay prior to destroy a connection to prevent exception handling
|
|
|
-- Minor logs changes

+# Pascal - A One of a kind Cryptocurrency
|
|
|
|
|
|
+**Pascal is an instant, zero-fee, infinitely scalable, and decentralized cryptocurrency with advanced privacy and smart contract capabilities. It's the world's first blockchain independent of historical operations.**
|
|
|
|
|
|
-### Build 1.5.2.0 - 2017-03-03
|
|
|
+**Pascal possesses unlimited potential.**
|
|
|
|
|
|
-- Added a jobs buffer for miners. This will allow to submit old job solutions (limited buffer). (Fix the "tx" issue)
|
|
|
-- Miner jobs will not be sent every time a transaction is received, thet will be buffered and sent every few seconds (Fix the "tx" issue)
|
|
|
-- Better network performance, allowing more operations and nodes thanks to buffering before relaying
|
|
|
-- Daemon: Allow select on ini file how many connections can handle
|
|
|
-- Fixed a locking when deleting connections

|
|
|
-- Improved network connection
|
|
|
-- Added JSON-RPC port 4003 protection Whitelist (only allowed IP's can use JSON-RPC)

|
|
|
-
|
|
|
-- JSON-RPC modifications:
|
|
|
- - New param "b58_pubkey", can be used instead of "enc_pubkey": b58_pubkey is a Base58 encoded public key with checksum, is the value that Wallet exports/imports public key
|
|
|
- - New JSON object type Public Key: "name","can_use","enc_pubkey","b58_pubkey","ec_nid","x" and "y" for each public key
|
|
|
- - Added params "start" and "max" to "getaccountoperations". By default deep=100, max=100 and start=0, so will return last 100 operations made to an account
|
|
|
- - Added params "start" and "max" to "getblockoperations". By default max=100 and start=0, so will return last 100 operations made to a block
|
|
|
- - Added params "start" and "max" to "getwalletaccounts". By default max=100 and start=0, so will return first 100 accounts of the wallet
|
|
|
- - Added params "start" and "max" to "getwalletpubkeys". By default max=100 and start=0, so will return first 100 public keys of the wallet
|
|
|
- - Will return a Public key JSON object
|
|
|
- - Method "decodepubkey" allows params "enc_pubkey" or "b58_pubkey" (if used together, returns error if not match)
|
|
|
- - Will return a Public key JSON object
|
|
|
- - Method "changekey" allows params "new_enc_pubkey" or "new_b58_pubkey" (if used together, returns error if not match)
|
|
|
- - Method "getwalletaccounts" allows params "enc_pubkey" or "b58_pubkey" (if used together, returns error if not match)
|
|
|
- - Method "getwalletaccountscount" allows params "enc_pubkey" or "b58_pubkey" (if used together, returns error if not match)
|
|
|
- - Method "getwalletcoins" allows params "enc_pubkey" or "b58_pubkey" (if used together, returns error if not match)
|
|
|
- - Method "payloadencrypt" allows params "enc_pubkey" or "b58_pubkey" when payload_method="pubkey" (if used together, returns error if not match)
|
|
|
- - Method "addnewkey" changed. Does not return an HEXASTRING with enc_pubkey, now returns a public key JSON object
|
|
|
- - New methods:
|
|
|
- - Method "changekeys". Similar to "changekey" but for multiple accounts at param "accounts" as a coma separated string (ex: "accounts"="1248,1753,85056"). Returns a JSON object with result information
|
|
|
- - Method "lock" to lock wallet. Returns true if locked, returns false if wallet has no password (an empty string, must put a new password prior to lock)
|
|
|
- - New method "getwalletpubkey". Search for "enc_pubkey" or "b58_pubkey" and returns a Public key JSON object
