Signum Development, Roadmap, and History

Signum Development

The main point of contact and official developer for Signum is The Signum Network, an organization consisting of program engineers, marketing professionals, community organizers, technical support, and consultants.  Associated individuals can be contacted on the Signum Discord channel and identified by the designated role of “”.

Signum entered a new period in 2021 with a special emphasis on marketing, starting with a significant and universally popular rebrand.  Marketing was often downplayed in favor of organic growth that well-developed technology would draw. It was felt that it would bring growth that could exceed the ability of the relatively small community to support.  Signum has always had skilled programming engineers and a strong community; The rebranding is a way of tidying up the years of development, moving beyond a few pitfalls in distant memory, and going forward under a new moniker that is more suitable and meaningful for the platform.

In 2019 and 2020, Signum experienced its most significant technological advancements to date.  There were several successful hardforks, many new advanced features, and a stunning amount of progress in overall ease-of-use and accessibility, particularly in the areas of smart contracts, database performance, and network capacity.

2021 is off to a great start; progress and innovation a seemingly daily occurrence.


The Roadmap is a planning document that shows the current development focus for Signum in the context of planned development, current projects, recent accomplishments, ongoing refinements to existing products, ongoing promotional projects, and history.  It helps us to share what we have accomplished, what we are working on next, and the general direction we are taking.  The roadmap is intended to be accessible and clear enough to open and facilitate a practical dialogue with the community.

Signum History

2021 June

  • Burstcoin rebranded as Signum and The Signum Network.  A new logo, based on a celtic knot, was adopted to replace the existing Burstcoin logo which was represented as a stylized letter B within a blue or black circular background.


2020 November

2020 July

  • Released BTDEX, a decentralized exchange system running on the blockchain.  It implements a unique non-custodial exchange method for cryptocurrencies and conventional fiat currencies based on BlockTalk Smart Contracts and on-chain encrypted messages.  The exchange method is serverless.  Fees are distributed among Trade Token (TRT) holders./li>

2020 June

  • On the 20th of June 2020, a successful hardfork at block 765,000 was initiated to implement CIPs 20, 22, 23, 24, and 25. The two main goals of the hard fork were to stabilize the 4 minute average block time and improve the smart contract framework.

2020 March

  • 2020-03-10: Version 2.5.0 updated smart contracts, allowing for 50 times larger complexity with lower fees

2019 November

  • With the release of the mobile version of Phoenix, CIP-18 was implemented.  Phoenix is a Cross-Platform Wallet Application developed to support mobile devices, including iOS and Android.  This wallet feature increased security and a refreshed look and feel.

2019 October

  • Burstcoin listed on the Eterbase exchange with FIAT and stablecoin pairings (EUR, USDT, BTC, ETH, EBASE, XBASE, XBASE-B)

2019 July

  • New pool software released, giving pool operators the freedom to operate pools without license restrictions.
  • Burstcoin listed on the STEX exchange (BURST/BTC)
  • BRS 2.4.0. released with integrated Multi-Out payments giving recipients the ability to see these transactions alongside other transactions.  (CIP-19)

2019 June

  • BlockTalk is an extended smart contract framework that aids in the creation and deployment of contracts.  New contracts are written in Java with a simple interface for testing and deploying to the Burstcoin blockchain.  BlockTalk includes tools and code snippets to assist in the process and helps to manage the minimal fees involved with running the contract on-chain.  As a result of this extensive development, NFTs ( non-fungible tokens ) were introduced.  These smart contracts have the unique feature of ownership.  The first Burstcoin-NFT was Koh-i-Noor.

2019 May

  • Phoenix Wallet powered by BurstJS released.  BurstJS is a powerful JavaScript library for building Burstcoin applications.  ( CIP-18 )
  • Without notice,  Poloniex delisted a large number of cryptocurrencies, including Burstcoin, on May 10th.  The decision to close the order book caused a nearly 50% price drop.

2019 January

  • On January 3rd, 2019, the PoC Consortium stepped back from the role of development.  The Burst Applications Team and the Burst Marketing Fund began as the new lead developers.

2018 June

  • On the 11th of June, Burstcoin initiated a successful hard fork at block 500,000 to implement multi-out payments.  Before the hard fork, Burstcoin was able to support 255 transactions per block (44,880 bytes).  After the hard fork, each block was adjusted to 1020 * 176 bytes (for a total of 179,520 bytes).  This increased supported transactions per second to 80, or a minimum of 367,200 on-chain transactions per day, up to a maximum of 6,912,000 on-chain transactions per day.


  • Burstcoin replaced the minimum fee of 1 BURST ( now Signa ) per transaction with a dynamic fee schedule starting with .007357 during periods of low network activity.  The previous fee of 1 BURST had been set as a disincentive for denial of service attacks on the network.  With the new schedule, transactions can be initiated for the lowest fee even during periods of high network activity, but they are delayed until a slot for the transaction becomes available.
  • POC1 to POC2:  To address a theoretical vulnerability referred to as a grinding attack, Burstcoin preemptively updated the format of its plot files while increasing the read speed by 50%.

2017 December

  • On December 27th, 2017, the PoC Consortium developers released a new white paper titled The Burst Dymaxion.  It described implementing a tangle-based lightning network allowing for arbitrary scalability and anonymous transactions and payment channels using directed acyclic graph (DAG) technology on top of the Burstcoin blockchain.  Although the focus of Burstcoin development shifted away from this white paper’s end goal and toward Burstcoin’s smart contract functionality, many of the required preparatory improvements were made and continue to benefit development.  One example is the development of the PoC2 protocol, which eliminated the theoretical vulnerability of P0C1 to grinding attacks. 
  • December 22nd, 2017:   Coin of the day: Burstcoin — First truly Green coin and most overlooked coin. Uses 400 times less power than Bitcoin. Super secure and private. Includes smart contracts, encrypted messaging, decentralized wallet, libertine blockchain—most undervalued coin.        — John McAfee (@officialmcafee) December 22, 2017

2017 August

  • In the aftermath of the spam attack, the Proof-of-Capacity Consortium (PoCC) was formed to continue developing Burstcoin.  The original announcement was posted on August 11th of 2017, the third anniversary of the Burstcoin blockchain:

2017 July

  • On July 22nd of 2017, a denial of service attack (DoS) was launched against the Burstcoin network, causing many nodes to crash and the network to split into multiple forks.  Poloniex disabled deposits and withdrawals until August 10th while the network stabilized.  In response to the attack, Burstcoin initially implemented a hard cap on the number of unconfirmed transactions that a node could hold in memory.  Subsequently, a configurable limit was made available so that each node could set independently set limits according to their own memory and computational resources.


  • Because of differences within Burst Team, several members started Burstnation by the end of 2016.  The differences continued until leading Burstnation members announced their retirement from the Burstcoin community after the release of the Dymaxion white paper.  Burstnation can be credited with expanding the Burstcoin community through its leader’s prolific and sometimes colorful promotional activities:

2015 August

  • After the original developer of Burstcoin disappeared, a community quickly formed under the name Burst Team in August of 2015. Development of the wallet software continued as a fork of the original project on Github:

2015 May

2015 April

2015 February

2014 December

2014 April

2014 September

2014 August

Burstcoin, rebranded as Signum in June of 2021, was launched in 2014.  It was released to the public on August 10th of that year on by the original developer using the pseudonym “Burstcoin”.  The original developer disappeared without explanation.  Their identity is unknown.
