Jednadvacet

That is how Jednadvacet now welcomes visitors to its website, and it neatly explains why the network exists. Bitcoin can be studied alone, but a beginner often needs to ask a simple question of someone sitting opposite: how do I recognise the right address, what should I back up, or why is a transaction waiting? Local groups therefore meet over a beer, at family picnics and during lectures. The informal setting lowers the barrier to a first visit. [1]

Jednadvacet is a common directory and identity, not a headquarters running every evening across the country. A meeting in Brno may feel different from one in a small town, and the programme depends on the people arranging it. The international Twentyone World network follows a similar principle: durable local communities in their own language, rather than a mere list of one-off events. Connection makes groups easier to find but does not remove local responsibility. [1] [2]

As of 22 October 2026, the website lists a presence in 47 towns. The number tells us how many local contacts appear on the map, not how many people attend each month. One group may be thriving, while another is just beginning or waiting for a new organiser. The best check is therefore simple: open the town page, write to the contact and ask when the next meeting is taking place. [1]

A point can be added to a map quickly; relationships take longer. Twentyone World distinguishes a community from a one-off meetup through regular contact, local language and someone willing to take responsibility for what comes next. A new group therefore needs more than a logo and a name. Someone has to find a place, let people know, come back even when turnout is small, and create an atmosphere in which a beginner feels comfortable asking questions. [2]

The shared calendar shows what is happening beyond a visitor’s own town and can be added to a calendar application. The website asks anyone who wants to add events to first write to the contact email provided. Community plans still move: a venue may close, a speaker may become ill or a date may shift. Before travelling across the country, it is sensible to open the event details and confirm the time and place with the organiser. [3]

An in-person meeting often ends with a longer list of questions. The Studuj Bitcoin page therefore organises free resources that do not require registration, including unit converters, charts, statistics and network explorers. It is neither a closed textbook nor a promise that every link will remain the best choice forever. Services change terms and sometimes disappear. The value of the list is that a beginner does not have to wander through search results entirely alone. [4]

The Finance page lets people apply for a contribution to a Bitcoin-related activity. Donations to the community are handled on a separate page, Podpořit, which lists payments through Lightning Network, a network for fast bitcoin payments without recording every individual payment on the blockchain. It also offers a way to donate some mining hash rate through Braiins Pool, a service that brings miners together and distributes rewards for their work; according to the site, the pool sends contributions once a day to the community’s Lightning wallet. Shared funds can therefore help smaller local projects too. Support is still allocated through a specific process; submitting a request does not guarantee money. [5] [6]

Jednadvacet also publishes partners such as Trezor, Firefish, Štosuj.cz, 21energy and BTC Prague. The website explains that purchases through the listed links support the community. Such a partner or affiliate link can bring a service a customer and the community a referral payment. Non-profit partners that do not provide financial support are listed separately. That disclosure is better than a hidden commission, but it is not an independent product test. A wallet purchase, loan or other financial step still requires a separate review of the service and its terms. [6]

A separate project is working toward a Bitcoin monument in Prague. In a vote held from 28 May to 1 June 2026, 30 votes to 3 approved a committee and CZK 100,000 for the design-competition route. The project explicitly describes Jednadvacet as an informal network and uses The Malahar Network, z. s. as a legal home. Community approval for one initiative therefore does not create a permanent government over all local groups. [7]

The fundraiser rules price the work from Satoshi Gallery at 1 BTC and set a maximum target of 1.3 BTC including other costs. At the review date, they still describe negotiations over a permanent location in Prague. Two situations matter here. If the basic target is not reached, the funds are to support preparations for a competition for an original Czech monument; some may go towards education through INEV. If money remains after buying, transporting and installing the statue, the committee decides how to use the surplus and publishes its reasons; its stated plan is to support the design competition. Automatic refunds to every donor are not promised. Before contributing, it is therefore worth understanding these possibilities as well as looking at the proposed statue. [8]
