  • Schnorr signatures have been proposed as a scaling solution by long-time developer and Blockstream co-founder Pieter Wuille.
  • Merkelized Abstract Syntax Trees (MAST) is a proposal by Johnson Lau which reduces the size of smart contracts (complex scripts), and increases their privacy.
  • A 2006 paper by Mihir Bellare enables signature aggregation in O(1) size, which means that it will not take more space to have multiple signers. Bellare-Neven reduces to Schnorr for a single key.[7] Bellare-Neven has been implemented.[8][9][better source needed]

  • In 2015, BIP100 by Jeff Garzik and BIP101 by Gavin Andresen were introduced.
  • Bitcoin XT was proposed in 2015 to increase the transaction processing capacity of bitcoin by increasing the block size limit.[11]
  • Bitcoin Classic was proposed in 2016 to increase the transaction processing capacity of bitcoin by increasing the block size limit.
  • “The Hong Kong Agreement” was a 2016 agreement of some miners and developers that contained a timetable that would see both the activation of the Segregated Witness (SegWit) proposal established in December 2015 by Bitcoin Core developers, and the development of a block size limit increased to 2 MB. However, both timelines were missed.
  • SegWit2x was a proposed hard fork of the cryptocurrency bitcoin. The implementation of Segregated Witness in August 2017 was only the first half of the so-called “New York Agreement” by which those who wanted to increase effective block size by SegWit compromised with those who wanted to increase block size by a hard fork to a larger block size.[12] The second half of SegWit2x involved a hard fork in November 2017 to increase the blocksize to 2 megabytes. On 8 November 2017 the developers of SegWit2x announced that the hard fork planned for around 16 November 2017 was canceled for the time being due to a lack of consensus.
  • Bitcoin Unlimited advocated for miner flexibility to increase the block size limit and is supported by mining pools ViaBTC, AntPool and investor Roger Ver.

    As you know, the world of cryptocurrency is extremely large, full of possibilities, and it is certainly very difficult to keep up with all the changes in the sector, especially given the multitude of players that appear with each innovation. However, in 2020, one platform is particularly talked about. This is and here we will detail why this platform has made such noise. Let’s go ! claims to be a versatile online platform which tends to encompass in a sprawling way all activities related to cryptocurrencies and associated tokens. Thus, you will absolutely not be surprised to learn that at the foundations of the platform is the coin, or CRO, who is the official platform token ! This same token is also very far from being figurative as it plays a central role in the functionality of the platform. As of this writing, CRO is the 14th largest crypto in the world according to

    As a reminder, a token is a digital asset based on a blockchain, most of the time the Ethereum blockchain. However, the CRO relies on’s own blockchain which is a public and opensource blockchain.

    So, all of’s functionalities are based in part on the possibility of staking the CRO in order to obtain many advantages. Staker a token designates the fact of blocking this token for a given period, thus preventing the transfer to another wallet of this token or the sale of it. In fact, the token is as if frozen and is immobilized for the duration of the staking. is a centralized trading platform, or CEX. The exchange claims to offer lower fees compared to the competition and have the best execution prices.

    Within this particular exchange, we find the Syndicate, which is a marketplace where you can buy tokens from projects that the teams have found to be interesting. These tokens are then offered at reduced prices, if certain conditions are met, particularly temporal (being there at the right time, when the offer is in progress) and cash (having a certain amount of staked CROs). Thus, the tokens at reduced prices are exchanged for…. CRO !

    The mobile application provides access to almost all the features of the platform. It also allows you to manage your wallets and what they contain, but also to monitor changes in cryptocurrency prices. The application also provides access to the various services that we will list below.

    This system called Crypto Earn is based on the fact that many cryptocurrencies, different from the CRO can be staked and actually bring interest. Thus, via you can stake cryptocurrencies and receive interest that is proportionally boosted by the CROs you hold. The more CROs you store on the platform, the more interest will be generated by staking all your cryptocurrencies. However, this system requires a minimum investment, that is to say that there is a minimum of capital that one must have to benefit from the functionalities Crypto Earn. These amounts vary depending on the different cryptocurrencies.

    In addition, there are several staking formulas: flexible, 1 month and 3 months. The longer you store, the more interest you will earn. Awesome isn’t it?

    Interest earned goes directly to your wallet every week. This changes somewhat from the wonderful world of DeFi where it is sometimes necessary to claim your tokens manually!

    The platform also offers to entrust your crypto to trading bots or algorithms that will take care of moving your funds for you. No need to have any trading knowledge to take advantage of opportunities linked to the volatility of cryptocurrencies. There are several bot profiles depending on the level of risk taking you want for your investment. The lower the risks, the more interest you will earn from trading. Conversely, big risk is easily associated with big potential gain but also big potential loss. There are therefore three levels of risk on, from the most aggressive to the safest: growth, balanced and conservative..

    On the model of what is currently done in the world of DeFi, it is possible to obtain loans thanks to collaterals which guarantee the borrower’s solvency. Of course for, the interest rate goes down with a large number of staked CROs. It is important to note here that although in appearance very similar to loan DeFi products, this is a fully centralized service.. This is not necessarily without advantage, because it allows, for example, to completely remove the notion of repayment period for these loans. offers to deploy VISA payment cards connected to your crypto wallet ! Convert your cryptos directly into euros by drawing at an ATM! cards offer many benefits which largely depend on how many CROs are staked and for how long. Staking is not completely necessary for the use of the CRO card but however absolutely vital to enjoying the many associated benefits : cashback of up to 8% each time the card is used, reimbursements for subscriptions such as Netflix or Spotify, reimbursement of up to 10% on platforms such as AirBnB and Expedia. To take advantage of these advantages, you just need to use the card as a means of payment.

    These cards also have other advantages, such asno annual fees and withdrawal fees (capped according to the card).

    There are naturally several card ranges whose particularity is that they are made of metallic material. I’ll let you see the benefits of these different cards in the image below.

    Here is one of the great strengths of Indeed, the platform allows online stores to accept cryptocurrencies as a means of payment. This payment method allows merchants to save a great deal on fees associated with the payment process (with each purchase you make online, the merchant pays a variable tax to their payment provider). Thus, traders accept cryptos as a means of payment and automatically receive fiat currencies according to preference. This payment module is compatible with several CMS including WooCommerce.

    Finally, now offers a decentralized wallet service in order to fully exploit DeFi and its growth. then deploys a swap service, similar to UniSwap, a farming service, but also another mobile application, DeFi wallet, which plays a role similar to that of a MetaMask for example.

    Today, and after the brief description about the platform, it is obvious that this is a serious titan in the field of cryptocurrencies. Its expansion is extremely impressive, especially considering that its development only started in 2016! This platform has a significant strength which lies in its versatility. Indeed, the blockchain and cryptocurrency environment being particularly fertile in terms of innovation, we are witnessing a rapid proliferation of tools and platforms.

    Where the platform hits hard is that the more its development progresses over time, the more the platform resembles a new kind of bank: possibility of subscribing to a loan, possibility of investing, possibility of obtaining a card. VISA payment, etc … It is then particularly relevant to be interested in the birth of such a structure and to observe its evolution in particular what it does with the initial values ​​of the cryptocurrency in the long term but also what the legislators to him will do. In any case, we will not fail to keep you informed of the significant developments of!

    Coming from the medical world, I am passionate about cryptocurrencies and blockchain technologies. I am firmly convinced that these technologies will be a real pivotal point in the years to come with regard to the various ethical uprisings relating to data, and more particularly to transparency. I am also a big fan of DeFi. In addition, I am attached to the University of Paris.
