NXT : 十年源头代码的回溯与展望
链上财经Plus 2023-12-06 07:51 Posted on 广西


11月28日,区块链领域的开山鼻祖之一NXT上线十周年。十年弹指一挥间,从2013年最初基于密码学证明思想构建的NXT,到今日仍在不断拓展与优化的Ardor(NXT 2.0)生态。我们不妨利用这个契机,回溯一下这个源头级公链的创新之路。

NXT: ретроспектива и прогнозы
Chain Finance Plus 2023-12-06 07:51 Posted on Guangxi

28 ноября NXT, один из базовых проектов всей блокчейн-вселенной, отметил десятилетний юбилей. Десять лет пролетели в мгновение ока, от основания NXT в 2013 году, до сегодняшней всё расширяющейся экосистемы Ardor (NXT 2.0). Мы можем воспользоваться этой возможностью и проследить инновационный путь этой публичной цепочки от самого её основания.

В 2013 году, когда блокчейн-проекты представляли собой в основном копирование кода Биткойна и доработку алгоритмов майнинга, NXT стал чем-то невероятным. NXT - это полностью переписанный код, использующий механизм proof-of-stake, выпускающий фиксированное общее количество токенов, не требующий майнинга и смарт-функции, поддерживаемые его блокчейном. NXT имеет встроенные модули для краудфандинга, торговли и голосования, а также расширяемый дизайн, что дает разработчикам основу для дальнейшего расширения его возможностей.

Истоки NXT восходят к сентябрю 2013 года, когда таинственный пользователь BCNext объявил о своем проекте на биткойн-форумах. Изначально встреченная со скепсисом, версия 1.0 была выпущена в ноябре 2013 года и начала работать, вызвав интерес тысяч пользователей. NXT отказывается от "борьбы за власть", характерной для майнинга POW, в пользу алгоритма Proof of Stake (POS). Он прост и эффективен, и за десять лет работы ни разу не подвергался успешным атакам.

Вскоре после запуска платформа продемонстрировала преимущества своей гибкой конструкции. Благодаря встроенным смарт-контрактам можно быстро добавлять новые функциональные модули. Среди запущенных функций: псевдонимы учетных записей, биржи активов, рыночные площадки, валютные системы, голосования и т.д., что демонстрирует высокую способность к расширению, а также обслуживает большое количество проектов. Благодаря плагинам и расширениям сторонние разработчики могут подключать свои собственные приложения к основному программному обеспечению NXT, чтобы получить необходимые им функции.

В 2017 году основная команда разработчиков использовала опыт создания NXT для инкубации и запуска многоцепочечной архитектуры платформы Ardor. Токены Ardor были распространены среди всех держателей NXT посредством airdrop. Сегодня NXT по-прежнему служит сторонним разработчикам в качестве стабильной публичной цепочки. Согласно специальной лицензии, любое программное обеспечение, созданное на ее основе, выпускается с открытым исходным кодом, а токены распространяются по воздуху, позволяя держателям NXT также получать прибыль.

За десять лет NXT пережил взлет и падение многих публичных цепочек. Он олицетворяет дух первопроходцев блокчейна и стал образцом для разработчиков. Теперь, став зрелой платформой с сотнями узлов, NXT продолжит работать под руководством своих сторонников, команды Jelurita, и будет и дальше вдохновлять начинающих разработчиков.

Release 1.12.1

https://www.jelurida.com/nxt/downloads

Change log:

This stable release is a mandatory upgrade for all mainnet Nxt nodes.

A hardfork to activate several new features that have already been enabled on
testnet in 1.12.0e has been scheduled for block 2870000, expected around April
15, 2020. The following new features will be activated on mainnet:

    Asset Dividends payment by asset or currency, allowing paying asset
    dividends not only in NXT, but also in any asset or monetary system
    currency.

    Asset Properties, setting arbitrary name/value metadata on assets.

    Asset Increase transaction, allowing asset issuers to increase the total
    number of asset shares available.

More details about the above features were published in the previous 1.12.0e
changelog.

Optimize checkpoint calculation by using hash of checkpoint block bytes
instead of hashing all intermediate transactions.

Simplified setting up https on a public node without the need for a reverse
proxy. The new pem.to.pkcs12.keystore.certbot.hook.sh script can be used to
convert an SSL certificate issued by Let's Encrypt to a keystore file that
the Nxt node can use. The run.sh script now supports authbind, if started with
the --authbind modified, to allow the Nxt software to listen on port 443
without having to run it as root.

A new managePeersNetworking API has been added, to allow disabling or
enabling the node peer networking at runtime. It takes a single "operation"
parameter, with possible values: "enable", "disable", and "query", and
requires the adminPassword when run on a public node.

Added a new GetEpochTime API, to return the blockchain epoch time given a unix
timestamp.

Added a new property nxt.stopDownloadHeight to allow forcing the blockchain
download to stop once a certain height is reached.

The compact.sh script has been improved to better reduce the database size.
A new property has been added, nxt.disableCompactOnShutdown=false to allow
disabling database compact on shutdown, for faster restarts during development.

A new property has been added, nxt.deleteProcessedVotes=true, to optionally
disable the deletion of votes records when trimming the votes table. Note
that even if votes are not deleted, re-calculation of poll results may require
data that are no longer available (such as account or asset balances at the
time of poll finish), unless a blockchain rescan is done, this is why the
default is still to delete old votes records.

Various UI fixes and improvements.

Release 1.12.0e

https://www.jelurida.com/

Change log:

This is an experimental release, enabling several new features on testnet
only at block height 2500000. All testnet nodes must upgrade to this release
before this block (expected Sept 1, 2019). This release can also be used on
mainnet but upgrade is optional.

New features:

Added Asset Dividends payment by asset or currency. This allows paying asset
dividends not only in NXT, but also in any asset or monetary system currency.

Added Asset Properties feature, to allow setting arbitrary name/value metadata
on assets. Any user can set a property on any asset, only the asset issuer or
the user who sets the property can delete it.

Added Asset Increase transaction, allowing asset issuers to increase the total
number of asset shares available.

The Asset Delete History has been renamed to Quantity Change History and now
shows both asset deletion and new shares issuance transactions.
The getAssetDeletes API has been deprecated and a new getAssetHistory API can
be used to retrieve asset deletions, increases, or both.

Asset Dividends by Holding, Asset Properties and Asset Increase are currently
testnet-only features and will be enabled on mainnet at the next planned
hardfork block, exact height to be announced later.

New APIs related to the above features:

getAssetHistory, increaseAssetShares, getAssetProperties, setAssetProperty,
deleteAssetProperty


Process management add-ons, APIs and UI:

When enabling add-ons using the nxt.addOns property, if a package name is not
specified, the nxt.addons package is assumed, therefore it is no longer needed
to specify the full package name for the default add-ons included in the
release.

Added StartForging and ForgingEncryptedConfig add-ons to facilitate management
of forging processes.

The StartForging add-on reads the passphrases stored in a plain text file, as
defined in the property nxt.startForgingFile, one passphrase per line, and
automatically starts forging with each of these accounts when the server is
started. Since passphrases are stored unencrypted, this add-on should only
be used on well secured servers, or with accounts of insignificant value, or
in test environments.

For a secure way of starting forging with multiple accounts on a remote server
the ForgingEncryptedConfig add-on can be used to store the passphrases of
forging accounts in an encrypted file. This add-on exports two APIs:
saveForgingEncrypted and startForgingEncrypted, used respectively to save the
list of forging passphrases in an encrypted file, and to start forging with
them by only submitting to the server the password necessary to decrypt this
file. Note that at runtime, the forging account passphrases will still be kept
in server memory, but when using these add-ons will never need to be stored on
disk, and will not need to be re-submitted to the server each time forging
needs to be started. These add-ons are useful when forging on a fully trusted
node, and having to restart forging remotely without a risk of exposing the
passphrases in transit.

Added StartFundingMonitors and FundingMonitorsEncryptedConfig add-ons to
facilitate management of funding monitor processes.

The StartFundingMonitors add-on will automatically start all funding monitors
configured in a JSON formatted file, as defined in the property
nxt.startFundingMonitorsFile. The JSON can be generated by manually starting
the funding monitors as desired, and using the GetFundingMonitor API to
retrieve the list of monitors in JSON format. The secretPhrase parameter needs
to be manually added to the JSON for each funding monitor.

The FundingMonitorsEncryptedConfig add-ons allow storing the JSON configuration
of funding monitors in an encrypted instead of plain text file, and starting
the funding monitors by submitting only the decryption password to the server.
It exports two APIs for this purpose, saveFundingMonitorsEncrypted and
startFundingMonitorsEncrypted.

The SaveEncrypted APIs require the admin passphrase when used on a remote node.
To prevent overwriting arbitrary files, they will only overwrite an existing
file located in the conf/processes directory and with a default for the add-on
filename; otherwise the file must not already exist.

An UI for the above ForgingEncryptedConfig and FundingMonitorsEncryptedConfig
add-ons has been added, accessible under the cogwheel/processes menu.

Accounts under account control are no longer allowed to start FundingMonitors.


Java programming API:

As an alternative to programming against the http API, the same API calls are
now accessible from java programs using the so called APICallers. Those are
available in the nxt.http.callers package, and code samples for how to use them
are provided under src/java/com/jelurida/ardor/client/api, demonstrating tasks
such as local signing, message encryption and decryption, waiting for a new
block, etc. When integrating the Nxt functionality in your java programs,
using APICallers is the recommended approach instead of accessing core Nxt
classes directly.


Light client networking improvements:

Bootstrap of API proxy - try to connect to known peers and if this fails,
connect to trusted nodes to get latest open API peers. The purpose is to
either have a node serving the proxy at start, or to know that the network
is down, and also to fix the problems caused by old initial peers.

Default bootstrap node is defined in nxt.properties:
nxt.proxyBootstrapNodes=nxt.jelurida.com;

The new bootstrapAPIProxy API can be used to refresh the latest open API peers
from the bootstrap node.


Performance and stability improvements and bugfixes.

Windows and Mac installations now use by default an embedded Open JDK 12
installation.

The H2 database now uses the newer MV_STORE format by default. Conversion to
this format however takes effect only when running compact.sh on an existing
database, or re-downloading the blockchain from scratch.

Updated Jetty to version 9.3.27, H2 to 1.4.199.

Release 1.11.15

https://www.jelurida.com/

Change log:

This is a critical bugfix release. IMMEDIATE update is mandatory for everyone.

Fixed validation of string fields length in transaction attachments.

Fixed locale issue affecting Turkish users.

Allow setting the Content-Type header of the API responses to application/json
instead of text/plain using the nxt.apiFixResponseContentType property. Default
is still text/plain to preserve compatibility.

Updated libraries to Jetty 9.3.24, Bouncy Castle 1.60, IzPack installer 5.1.3.

Release 2.1.2

https://www.jelurida.com/


Change log:

This is a critical bugfix release. IMMEDIATE update is mandatory for everyone.

Fixed validation of string fields length in transaction attachments.

This is a stable release and should be used for mainnet nodes too, however
lightweight contracts are still available only on testnet.

Changelly exchange integration is now available in the Ardor wallet:

https://nxtwiki.org/wiki/Changelly_Integration

Javadoc is now available for sample contracts and API callers

Release 2.1.1e

https://www.jelurida.com/

Change log:

This is an experimental release. It is a mandatory upgrade only for testnet
nodes, but can also be run on mainnet.

Contract Manager IntelliJ Plugin is now available to enable contract
deployment and management from inside the IntelliJ Java Development IDE.

The Contract Manager utility now supports contract verification which, given
a hash of existing contract deployed as cloud data and a Java source file,
compiles the source file and verifies that the resulting class file is
identical to the contract class file.

API callers are objects which enable simple integration of Java programs with
the Ardor APIs. Multiple code samples are provided under
./addons/src/java/com/jelurida/ardor/client/api to demonstrate tasks such as
local signing, fee calculation, message encryption and decryption, and waiting
for a new block.

Transaction voucher loading is now supported when logging in using remembered
passphrase.

Fixed coin exchange between parent and child chain.

Fixed decimal calculations for MS currency reserve and claim dialogs.

Release 1.11.14

https://www.jelurida.com/

Change log:

Updated the translation resource files.

Updated default peers, added checkpoint at height 1865000.

Интерестно как можно использовать токен nxt в бизнесе?

Не ассет, а монета.

Change log:

This is a feature-freeze release for the Ardor testnet. No more API changes or
feature additions are planned before launch, only bug fixes.

The source code is now included in the package, for a public review, under a
temporary evaluation license only.

Added getExecutedTransactions API. This new API accepts parameters: "chain",
"height", "numberOfConfirmations", "type", "subtype", "sender", "recipient",
"firstIndex", "lastIndex", and returns the transactions from the specified
chain executed at this height, or executed with at least that many number of
confirmations.
Both non-phased and phased transactions are returned. For phased transactions,
only those approved and executed at the specified height, or approved with at
least that many confirmations of the final approval transaction, are returned.
If height is specified, sender or recipient parameters are optional, otherwise
at least one of them is required.

Fixed UI bugs - base target calculation, missing asset control setup, asset
control local signing, calculation of deadline when doing manual transaction
bundling.
