Full clients verify transactions directly by downloading a full copy of the blockchain (over 150 GB As of January 2018).[101] They are the most secure and reliable way of using the network, as trust in external parties is not required. Full clients check the validity of mined blocks, preventing them from transacting on a chain that breaks or alters network rules.[7]:ch. 1 Because of its size and complexity, downloading and verifying the entire blockchain is not suitable for all computing devices.
In May of 2017, the world’s first ‘Lightning Network’ transaction took place using Litecoin, where 0.00000001 LTC was transferred from Zurich to San Francisco in less than one second. The open-source Litecoin software can be downloaded, used, modified and distributed by individuals without fear of corruption, as the independent verification of source code and binaries makes for a completely transparent process.

Welcome to the 32nd Coin Report. In today’s report, I will be assessing the fundamental and technical strengths and weaknesses of ExchangeCoin. This will be comprised of an analysis of a number of significant metrics, an evaluation of the project’s community and development and an overview of its price-history. The report will conclude with a grading out of 10. ExchangeCoin was launched in November 2017 with an ICO that raised 650 BTC, equating to over $5,000,000 at the time. The token issued, EXCC, has a maximum supply of 32,003,133, with 4mn EXCC sold during the ICO. Further, the project also has a premine of 12.1mn EXCC, equating to 37.95% of the maximum supply (from which the 4mn was sold to the public in the token sale). The token itself operates on the Equihash algorithm, and underwent a hard fork in July 2018, after which the network migrated to a dual Proof-of-Work/Proof-of-Stake consensus mechanism, with 30% of block rewards rewarded to stakers and 70% to miners. The block reward is progressively diminishing, with the current reward at 24.5 EXCC per block, with 2.5-minute block times.
Although there are some similarities between BTC and LTC, you can’t define Litecoin without pointing out some key differences, such as instant and near-zero cost transactions, increased speed of adding a new block into the Blockchain (2.5 minutes against 10 in the Bitcoin network) and a scrypt usage in its Proof-of-Work process to make it easier for regular PC users to mine new blocks against ASIC miners. It is also one of the first cryptocurrencies that adopted SegWit.
Як правило, є верхня межа загального обсягу емісії[2] [4][8] . Однак у деяких криптовалют, таких як PPCoin, Novacoin, Sifcoin та інших відсутня фіксована верхня межа загального обсягу емісії[9] і можлива як емісія за рахунок наявних накопичень[9], так і деміссія шляхом обов'язкового знищення невеликої фіксованої суми в кожній транзакції. Всі існуючі на даний момент криптовалюти використовуються псевдонімно — всі транзакції публічні, але прив'язки до конкретної людини за замовчуванням немає, проте особу користувача може бути встановлено, якщо відома необхідна додаткова інформація. Ведеться розробка Zerocoin, де планується замінити псевдонімність на анонімність[10][11][12][13].
Сфер применения для таких умных контрактов очень много. Самое очевидное, например, использовать криптовалюту Эфир при выдаче займов населению. В таком случае кредитор может сразу прописать в условиях, когда, как и с какими процентами должна вернуться сумма кредита. Таких примеров при желании можно привести огромное количество, так как Ethereum фактически дает возможность создания своей денежной единицы в рамках любой национальной валюты.

In the blockchain, bitcoins are registered to bitcoin addresses. Creating a bitcoin address requires nothing more than picking a random valid private key and computing the corresponding bitcoin address. This computation can be done in a split second. But the reverse, computing the private key of a given bitcoin address, is mathematically unfeasible. Users can tell others or make public a bitcoin address without compromising its corresponding private key. Moreover, the number of valid private keys is so vast that it is extremely unlikely someone will compute a key-pair that is already in use and has funds. The vast number of valid private keys makes it unfeasible that brute force could be used to compromise a private key. To be able to spend their bitcoins, the owner must know the corresponding private key and digitally sign the transaction. The network verifies the signature using the public key; the private key is never revealed.[7]:ch. 5

Physical wallets can also take the form of metal token coins[108] with a private key accessible under a security hologram in a recess struck on the reverse side.[109]:38 The security hologram self-destructs when removed from the token, showing that the private key has been accessed.[110] Originally, these tokens were struck in brass and other base metals, but later used precious metals as bitcoin grew in value and popularity.[109]:80 Coins with stored face value as high as ₿1000 have been struck in gold.[109]:102–104 The British Museum's coin collection includes four specimens from the earliest series[109]:83 of funded bitcoin tokens; one is currently on display in the museum's money gallery.[111] In 2013, a Utahn manufacturer of these tokens was ordered by the Financial Crimes Enforcement Network (FinCEN) to register as a money services business before producing any more funded bitcoin tokens.[108][109]:80
Вместо того чтобы создавать новый блокчейн каждый раз, когда кто-то хочет создать свой дапп, можно использовать существующую инфраструктуру эфириума. Сравните строительство дома своими силами в чистом поле с наймом команды профессионалов, которые всё продумали за вас. Эфириум позволил практически каждому создавать собственные криптовалюты и даппы без особых проблем.
